METHOD OF PREPARING HYDROGEN HALIDE SALT OF HEXAALKYLTRIAMIDOPHOSPHAZOHYDRIDE Russian patent published in 2000 - IPC

Abstract RU 2157376 C1

FIELD: chemical industry. SUBSTANCE: described is method of preparing hydrogen halide salt of hexaalkyltriamidophosphazohydride which comprises reacting corresponding amine with trivalent phosphorus halide and halogen and subsequently aminating the resulting hexaalkyltriamido halogenphosphonium halide. Reaction is carried out in nonpolar organic solvent at temperatures from minus 40 C to plus 80 C. Method makes it possible to simplify process, increase yield of the final product and are readily available agents. EFFECT: more efficient preparation method. 5 cl, 5 ex
