QUATERNARY AMMONIUM PHOSPHITE COMPOUND AND ITS SYNTHESIS

摘要

PURPOSE: To obtain the compound effective for improving the hydrolysis resistance of a resin and useful as a resin stabilizer, flame-retardant, etc., by reacting a specific phosphite compound with an ammonium compound in the presence of an alkali. ;CONSTITUTION: The compound of the formula Ican be produced by reacting a secondary phosphite compound of the formula II (R is 1-18C alkyl, phenyl or methylphenyl) with a quaternary ammonium compound of the formula III (R₁ to R₄ are 1-18C alkyl or benzyl; X is halogen) in the presence of an alkali. The reaction is preferably carried out at room temperature to 100°C for 30min to 3hr using sodium hydroxide, etc., as the alkali.;COPYRIGHT: (C)1995,JPO
