摘要

A method is claimed for determining tributyl phosphate in a mixture of tributyl phosphate-kerosene mixture. The method is based on the formation of a complex upon addition of perchloric acid. The complex has the following composition, HClO sub 4 .1.5(C sub 4 H sub 9 O) sub 3 PO, and is insoluble in kerosene and in excess perchloric acid. The amount of tributyl phosphate is established by the volume of the middle layer formed under pressure of 1 part by volume of 9N perchloric acid to four volumes of mixture being analyzed.
