In the phosphonium salt and the production manner, and the portable catalytic converter between the magnetic particulate support phases which consist of the said phosphonium salt and on the portable reaction null magnetic substance particulate between the phases which use

摘要

PROBLEM TO BE SOLVED: To provide a phase-transfer catalyst separable and recoverable by magnetic force and enabling the reuse of the catalyst.;SOLUTION: A phosphonium salt supported on a magnetic fine particle, expressed by the figure and separable and recoverable by a magnet is used as a phase-transfer catalyst. In the formula, M is the magnetic fine particle; R¹ is a hydrocarbon group; R², R³ and R⁴ are each a hydrocarbon group and these groups may be bonded together to form a ring; R⁵ is a 1-3C alkyl; and X^- is an anion of an acid.;COPYRIGHT: (C)2008,JPO&INPIT
