CHEMICAL PROPERTIES of Hostapur SAS 60:
Hostapur SAS has good foaming power, which is very pronounced, especially in soft water.
Flash foam is a characteristic property of the secondary alkane sulphonates.
An increase in foaming properties, especially in hard water, can be achieved, for example, by a combination of Hostapur SAS with an alkyl ether sulphate in the ratio 4 : 1.
The good foaming properties of the Hostapur SAS/alkyl ether sulphate mixtures are clearly discernible.
Rheological properties of Hostapur SAS 60:
The viscosity of the aqueous Hostapur SAS solutions rises only slightly up to about 30 % active detergent.
Above 30 %, however, a rapid rise in the inhomogeneous paste region can be observed.

Storage of Hostapur SAS 60:
Hostapur SAS 60 separates out in storage into two phases, one containing more surfactant than the other.
In addition, sodium sulphate can separate out at fairly low temperatures.
Hostapur SAS 60 is, therefore, necessary to stir or pump round the tank contents constantly and at the same time to maintain a storage temperature of 65–90 °C.
If a circulating pump is used, entrainment of air must be prevented by suitable design of the return pipe.
The demands imposed on surfactants have changed in the last few decades.
Not only is an optimum price-performance ratio expected, but safety and impact on the environment are also prime considerations.
The secondary alkane sulphonate Hostapur SAS 60 meets these requirements in every respect.
Hostapur SAS 60 has been highly successful on the market for many years.
To date, over one million metric tonnes of Hostapur SAS have been produced in our European facilities.
One of the reasons for this great success is the enhanced environmental properties as shown by the life cycle assessment.
We are convinced that over the coming decades Hostapur SAS 60 will continue to maintain and expand its position as one of the leading principal surfactants.

The demands imposed on surfactants have changed in the last few decades.
Not only is an optimum price-performance ratio expected, but high safety and environmental compatibility are also prime considerations.
The secondary alkane sulphonate Hostapur SAS meets these requirements in every respect.
This surfactant has been highly successful on the market for many years.
To date, over one million metric tonnes of Hostapur SAS have been produced in our european facilities.
One of the reasons for this great success is the optimum environmental properties as shown by the life cycle assessment.
Environmentally friendly anionic surfactants for the detergent, chemical-technical and cosmetic industries, based on secondary alkane sulphonate sodium salt, starting product: n-paraffins.
m + n = 10 – 14; the sulphonate group is distributed over the carbon chain in such a way that it is mainly the secondary carbon atoms that are substituted.
Sulphoxidation, a basic reaction in aliphatic organic chemistry, was discovered as early as 1940 by C.
Platz at the Hchst site of the former IG Farben AG 7, when n-paraffins were treated with sulphur dioxide and oxygen and simultaneously exposed to ultraviolet light.
Since then the process has been developed into the present Hoechst light/water process 8 – 11, which can be described summarily by the following equation:
R-H + 2SO2 + O2 + H2O ? RSO3H + H2SO4
Substitution is done largely at the methylene groups; the terminal methyl groups are considerably less reactive. 12 – 14
The industrial-scale sulphoxidation of the n-paraffins by the Hoechst light/water process is carried out in a multi-lamp reactor.
The gas mixture of SO2 and O2 is introduced by means of gas injection equipment and on exposure to UV light produced in high-pressure mercury lamps made of quartz glass, sulphoxidation of the n-paraffins takes place in the presence of water.
The reaction gas is circulated.
A compressor is needed for maintaining gas circulation, as is a cooling system for adjusting the required temperature.
The reaction liquid is removed at the bottom of the reactor and the product phase the lower phase is separated in a separating system.
The upper phase – paraffin phase is cooled and replenished with water and n-paraffin and then returned to the reactor.
After concentration of the product phase in a vacuum, separation of the sulphuric acid and neutralization of the concentrate with sodium hydroxide solution, the remaining paraffin is driven off with superheated steam.
The distillate is again separated in a separator and the paraffin phase is returned to the reaction.
One characteristic of the process described is that no other chemical auxiliaries, for example, solid catalysts or solvents, are required.
The n-paraffins used for synthesis are obtained as a matter of course in the production of kerosene, and so Hostapur SAS manufacture offers a useful outlet for this material.
Because of their pronounced surface activity and specific properties, they have a very wide range of uses.
Their major use is in dishwashing liquids, in which Hostapur SAS has proved highly successful for over thirty years.
The Hostapur SAS †grades are used as principal surfactants in combination with other surfactants for the manufacture of virtually all types of detergents and cleaners for household and industrial use.
Hostapur SAS 60, by contrast, is a paste that flows at +20C but that separates out into two phases of different composition if left to stand for a lengthy period of time.
For this reason Hostapur SAS 60 must be homogenized before use by stirring and, if necessary, by heating.
This measure is not necessary if full drums are completely processed.
Fire extinguishing foams :
The pronounced flash foaming power of Hostapur SAS can be used in combination with other surfactants very effectively to formulate fire extinguishing agents.
Emulsion polymerization
Secondary alkane sulphonates have been used successfully for decades in the emulsion polymerization of vinyl chloride.
Hostapur SAS has proved successful both as an emulsifier in continuous and discontinuous processes and for the stabilization of the latex following polymerization by the nucleation process; in the latter process polymerization is carried out with only a low emulsifier concentration and the dispersion is stabilized subsequently by adding suitable emulsifiers.
Hostapur SAS is noted for its good dispersibility, which is evidenced by good stability of the latex to mechanical stress and good process control (little tendency for deposits to form in the reaction vessel).
Owing to the absence of double bonds, the emulsifier does not act as a radical interceptor.
This ensures a readily reproducible reaction course and results in end products with good heat stability because of the lower demand for persulphate (radical forming agent) and the lower tendency to block polymerization (no reaction between the emulsifier and the reaction partners).
The low salt content of Hostapur SAS also has a positive influence on the heat stability of the end product.
In the manufacture of butadiene copolymers, butadienestyrene and butadiene-acrylonitrile latices, soaps (fatty soaps, resin soaps) are generally used.
The soaps have the advantage over the synthetic anionic emulsifiers that the polymer can be precipitated by acidification or addition of salt and the fatty or resin acid remaining in the product serves as a plasticizer at the same time.
One evident disadvantage of the soaps is the instability of the latex (coagulation on slight change in pH and contamination, low resistance to fillers) and poorer chemical and heat stability.
For these reasons the synthetic emulsifiers are increasingly gaining ground, particularly for special products, for example, the carboxylated butadiene copolymers (for carpet backcoating, for papermaking, adhesives etc).
Because of Hostapur SAS 60s constant quality and low salt content, Hostapur SAS is highly suitable for this application.
Textile and leather auxiliaries:
Owing to Hostapur SAS 60s chemical stability and very good wetting action, Hostapur SAS can be used in the manufacture of synthetic fibres and in the finishing of textile fibres, for example, as an antistatic agent.
Other uses for the secondary alkane sulphonate are cotton scouring, mercerizing and carbonization and the preparation of leather fatliquors.
Hostapur SAS is also used successfully in the tertiary recovery of oil.
The Hostapur SAS grades are stable in the acid and in the alkaline pH range.
Detergent action of Hostapur SAS 60:
The good soil removal power of Hostapur SAS is not appreciably reduced by water hardness salts.
The builders used in practice increase the cleaning effect.
Solubilization of Hostapur SAS 60:
The good solubilizing power of Hostapur SAS towards hydrophobic oils and fats is characteristic of this type of surfactant.
In practical use in cleaners, this means increased degreasing and often a saving of solubilizers, for example, for perfumes.
The solubilizing effect rises with the surfactant concentration, the temperature and often also with the electrolyte content of the solution.
Solubilization in the Hostapur SAS solution can also be increased and speeded up by mechanical means and lengthy stirring
Emulsifying action of Hostapur SAS 60:
Secondary alkane sulphonates also display good emulsifying action.
As co-emulsifiers, they are suitable for the manufacture of liquid and cream oil-in-water emulsions.
Concentrations as low as under 1 % bring spontaneous emulsion formation in manufacture and an improvement in emulsion stability.
Moreover, finer distribution of the emulsified droplets is possible
Electrolyte stability of Hostapur SAS 60:
Hostapur SAS has only slight sensitivity to electrolytes.
The viscosity of the aqueous solutions is increased only slightly by additions of electrolyte such as sodium chloride or sodium sulphate.
