Patent number: 6730806Abstract: A process for preparing carboxylic esters. A catalytic distillation column filled with acidic catalyst in solid phase is utilized. Alcohol is fed from the bottom of the catalytic distillation column, and carboxylic acid or carboxylic anhydride is fed from the top of the catalytic distillation column in such a manner that the carboxylic acid or carboxylic anhydride can remain in the catalytic distillation column for a sufficient time to cause the esterification to produce the carboxylic ester and water. An esterification pre-reactor can be connected in series with the catalytic distillation column to facilitate the esterification.Type: GrantFiled: July 9, 2002Date of Patent: May 4, 2004Assignee: Industrial Technology Research InstituteInventors: Kuo-Ching Wu, Wen-Tzong Liu, Rey-Yue Chang, Chin-Shu Tsai

Patent number: 6630595Abstract: A method for producing maleimides. The method comprises reacting maleic anhydride and a primary amine at 100-180° C. in an organic solvent using a solid acidic catalyst, and purifying the maleimide produced therefrom by extraction and crystallization. The molar ratio of the primary amine to maleic anhydride is about 0.8-1.6. With the present invention, high production yield with high purity of maleimides can be achieved. In addition, the solid acidic catalyst can be easily separated and recycled for subsequent use. Thus, the present invention provides a number of distinct advantages, including substantially improved yield, conveniently reusable catalyst, reduced waste disposal and lower costs.Type: GrantFiled: June 4, 2002Date of Patent: October 7, 2003Assignee: Industrial Technology Research InstituteInventors: Kuo-Ching Wu, Yu-Lan Tung, Chiou-Hwang Lee, Jyh-Chang Dai, Chiung-Hui Huang
