PRODUCTION OF NAPHTHALENE POLYBASIC CARBOXYLIC ACID IMIDE

摘要

PURPOSE:To obtain an imide compound having excellent color tone and high purity in high yield. CONSTITUTION:A naphthalene polybasic carboxylic acid imide is produced by reacting a naphthalene polybasic carboxylic acid with a primary amino compound in an aliphatic monocarboxylic acid in the presence of 5-80wt.% of water in the reactional system.
