| titleOfInvention | Method for producing α, α′-dichloroadipic acid diester |
| abstract | (57) [Summary] (Modified) [Structure] Polyadipic acid polyanhydride is reacted with chlorine in the presence of a solvent to produce α, α'-dichloropolyadipic acid polyanhydride, which is then obtained. Α, α ′ of the formula (IV) characterized by reacting an anhydride with an alcohol in the presence of a solvent, and performing a series of steps in one pot -Method for producing dichloroadipic acid diester. (In the formula, R represents a linear or branched alkyl alcohol having 1 to 12 carbon atoms, an aryl alcohol, or an aralkyl alcohol.) [Effect] Using this production method, polyadipic acid polyanhydride and chlorine are used in a solvent. By reacting with and, by-products are significantly reduced, and as a result, α, α′-dichloroadipic acid polyanhydride can be obtained with high selectivity and in good yield. Furthermore, by continuously reacting with alcohol in a solvent and esterifying, α, α′-dichloroadipic acid diester can be obtained with a high selectivity and a high yield, and can be obtained in one pot, which has an extremely high industrial value. large. |
