METHOD FOR PREPARING TRIALKYLARSENITES UNDER CONDITION OF INTERPHASE TRANSFER Russian patent published in 2003 - IPC

Abstract RU 2215745 C2

FIELD: chemical technology, organic chemistry. SUBSTANCE: invention relates to technology for preparing arsenous acid alkyl esters (trialkylarsenites). Method involves effect of 18-crown-6 as catalyst of interphase transfer on process of interaction of arsine oxide with alcohol in removal of formed water by boiling in the presence of azeotrope- forming agent. Invention provides increasing yield of the end product, intensification of process in preparing trialkylarsenites due to elevation of reaction rate and enhancement of selectivity of process using the proposed catalyst. EFFECT: improved preparing method. 2 cl, 1 tbl, 2 ex
