Title:
脂環式テトラカルボン酸二無水物の製造方法
Document Type and Number:
Japanese Patent JP7052723
Kind Code:
B2
Abstract:
The present invention relates to a method for producing an acid dianhydride, which is characterized in that at least one of the two operations (A) and (B) described below is performed when an olefin compound is reacted with carbon monoxide. (A) After mixing a palladium compound, a copper compound and an alcohol compound in a reaction container, the resulting mixture is mixed with the olefin compound by sequentially performing the substitution operation (C-2) described below and the agitation operation (C-1) described below. (B) After mixing a palladium compound, a copper compound, an alcohol compound and an orthoester compound in a reaction container, the resulting mixture is mixed with the olefin compound by performing the substitution operation (C-2) described below. (C-1) To agitate in a carbon monoxide atmosphere. (C-2) After reducing the pressure of the reaction container, an operation of sealing a carbon monoxide gas therein is performed once or more times.
