TRIBUTYL PHOSPHITE Usage And Synthesis

Chemical Properties

Clear colorless liquid

Uses

Tributyl phosphite may be employed as model lubricant additive and its surface chemistry on Fe3O4 in ultrahigh vacuum is investigated.

Uses

Tributyl Phosphite inhibits fluoroacetanilide poisoning in mammals.

Uses

Tributyl phosphite may be employed as model lubricant additive and its surface chemistry on Fe₃O₄ in ultrahigh vacuum is investigated.

General Description

Tributyl phosphite is an alkylphosphite and is reported to inhibit carboxylesterase activity.

Purification Methods

Fractionate the phosphite with an efficient column. It is stable in air but is slowly hydrolysed by H2O. [Gerrard J Chem Soc 1464 1940, Fertig et al. J Chem Soc 1488 1957, Fields J Am Chem Soc 80 2358 1958, Gillis et al. J Am Chem Soc 80 2999 1958, Beilstein 1 IV 1527.]
