These amidino compounds are prepared by usual esterification of carboxylic acid compounds represented by the formula (II)R.sub.1 --COOH (II)with amidinophenol compound (III) and, if necessary, can be transformed into pharmaceutically acceptable acid addition salts thereof.Type: GrantFiled: October 24, 1984Date of Patent: February 11, 1986Assignee: Torii & Co. Ltd.Inventors: Setsuro Fujii, Takashi Yaegashi, Toyoo Nakayama, Yojiro Sakurai, Shigeki Nunomura, Toshiyuki Okutome

Patent number: 4482733Abstract: An improved process for preparing diaryl esters of dicarboxylic acids is disclosed, in which the esterification reaction is optimized by gradually increasing the temperature at which the reaction is being conducted according to a predetermined pattern. The temperature increase should be a function of the degree of esterification. The diaryl esters so prepared are useful in making linear polyesters.Type: GrantFiled: September 24, 1982Date of Patent: November 13, 1984Assignee: Occidental Chemical CorporationInventor: Gautam R. Ranade

Patent number: 4482732Abstract: An improved process for preparing diaryl esters of dicarboxylic acids is disclosed, in which the esterification reaction is optimized by removing water and other by-products of the reaction according to a predetermined pattern. The removal of water and other by-products of the esterification reaction is most easily carried out by a distillation means, and the rate of removal is controlled by varying the reflux ratio in the distillation means during the course of the esterification reaction. The diaryl esters so prepared are useful in making linear polyesters.Type: GrantFiled: September 24, 1982Date of Patent: November 13, 1984Assignee: Occidental Chemical CorporationInventor: Gautam R.
