用途
使用
Tributyl phosphite may be employed as model lubricant additive and its surface chemistry on Fe3O4 in ultrahigh vacuum is investigated.
一般的な説明
Tributyl phosphite is an alkylphosphite and is reported to inhibit carboxylesterase activity.
製法・合成法
純化方法
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.]
