Purification Methods
TEHP, in an equal volume of diethyl ether, is shaken with aqueous 5% HCl, and the organic phase is filtered to remove traces of pyridine (used as a solvent during manufacture) as its hydrochloride. This layer is shaken with aqueous Na2CO3, then water, and the ether is distilled off at room temperature. The ester is then filtered, dried for 12hours at 100o/15mm, and again filtered, then shaken intermittently for 2days with activated alumina (100g/L). It is decanted through a fine sintered-glass disc (with exclusion of moisture), and distilled under vacuum.

Phosphate Esters as Flame Retardants
ATAMAN KIMYA Product News
The need for flame retardancy in consumer goods is apparent.
Each year there are over a million fires in the U.S. alone, resulting in thousands of deaths and injuries and billions of dollars in damage.
Addition of a flame retardant to items found within building structures or vehicles can help to both slow the rate of burning and suppress the smoke created from the fire.
Phosphate esters are a halogen-free alternative flame retardant and also have the added bonus of acting as a plasticizer in plastic formulations.
As a flame retardant, organophosphate flame retardants (OPFRs) bring the advantage of low smoke, low toxicity, low corrosion and no molten dripping during fire
1. Phosphate esters, such as Tributyl Phosphate (TBP), Tris-(2-Ethylhexyl) phosphate (TOF), and tris (2-butoxyethyl) phosphate (TBEP), are idea for applications such as artificial leather for applications such as motorcyclist jackets, flight or automotive upholstery leathers where both flame retardance and halogen-free formulation are preferred.
But these OPFRs are also used to plasticizer various other material and are compatible with unsaturated polyester resins, cellulose acetate, polyvinylchloride, acrylonitrile-butadienestyrene, synthetic rubber, floor wax, and rubber.
