Patent number: 7781618Abstract: The present invention relates to a method for producing an unsaturated aliphatic primary amine including subjecting an unsaturated aliphatic nitrile having 16 to 22 carbon atoms to hydrogen reduction in the presence of ammonia using a hydrogenation catalyst to produce an unsaturated aliphatic primary amine, wherein 0.01 parts by weight to 1.0 part by weight of aromatic carboxylic acid amide is added based on 100 parts by weight of the unsaturated aliphatic nitrile, and a partial pressure ratio of ammonia to hydrogen is adjusted to 8/2 to 6/4. The present invention also relates to an unsaturated aliphatic primary amine, which is produced by the production method.Type: GrantFiled: March 5, 2008Date of Patent: August 24, 2010Assignee: Lion Akzo Co., Ltd.Inventors: Michito Makimura, Hiroyuki Izumoto

Patent number: 7718816Abstract: To provide: a carboxamide derivative having reduced content of amide ester; a method for producing thereof; and a detergent composition containing the carboxamide derivative and having excellent low-temperature stability. One method for producing a carboxamide derivative is to react carboxamide, produced with a manufacturing method of carboxamide including 0.02% by weight to 0.18% by weight of amide ester, with hydrogen peroxide, wherein the method includes a carboxamide synthesis process to synthesize carboxamide by reacting diamine with fatty acid ester at a molar rate of 1.20 to 1.60. Another method for producing a carboxamide derivative is to react the carboxamide with monohaloalkylcarboxylic acid or a salt thereof. A carboxamide derivative is produced by the method for producing a carboxamide derivative. A detergent composition includes the carboxamide derivative. The carboxamide derivative is preferably amidoamine oxide or amide betaine.Type: GrantFiled: June 26, 2006Date of Patent: May 18, 2010Assignee: Lion Akzo Co., Ltd.Inventors: Toshio Yajima, Akiko Kawashima
