    摘要: The present invention provides a silicone polymer production method that can achieve a significantly improved yield due to the needlessness of a rinsing step and can produce a stable a silicone polymer. The production method for a silicone polymer includes a step for preparing at least one silane compound selected from the compounds represented by the general formula (1); R a Si(OR 1 ) 4-a (1) (wherein R is a hydrogen atom or a monovalent organic group, R 1 is a monovalent organic group, and a is an integer of 1 or 2) and the compounds represented by the general formula (2); Si(OR 2 ) 4 (2) (wherein R 2 is a monovalent organic group), a step for hydrolyzing it with a quaternary ammonium compound in the presence of water, and a step for bringing it into contact with a cation exchange resin.

    摘要: When a salt of an amine and an optically active diacyltartaric acid, or a diastereomer salt of an optically active amine and an optically active diacyltartaric acid, obtained by optically resolving a racemic amine using the optically active diacyltartaric acid, is salt-exchanged with an acid aqueous solution, the optically active diacyltartaric acid is added in the acid aqueous solution beforehand.
    Furthermore, a raw material containing a racemic amine and an optically active diacyltartaric acid is optically resolved, and the diastereomer salt of the optically active amine and the optically active diacyltartaric acid respectively of one isomer type, is separated. The obtained diastereomer salt is dissociated using an acid aqueous solution containing the optically active diacyltartaric acid, for recovering the optically active diacyltartaric acid, and the obtained' optically active diacyltartaric acid is recycled into an optical resolution step as a raw material of the optical resolution step.
