Title: Production of bisphenol a
Inventor: OOKUBO HIDEKAZU
IPC: C07B61/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To produce bisphenol A while improving the catalyst life by condensing acetone with phenol through dehydration in the presence of an organic high-molecular siloxane having both of a sulfone group-containing hydrocarbon group and mercaptomethyl group. SOLUTION: Acetone and phenol are condensed through dehydration in the presence of an organic high-molecular siloxane having both of a sulfone group- containing hydrocarbon group (preferably phenylsulfonic acid group) and mercaptomethyl group to provide the objective bisphenol A. The organic high- molecular siloxane catalyst can be prepared, for example, by a so-called sol-gel method of an alkoxysilane, a so-called preparation method by silylation, or the like. The condensation through dehydration of the acetone and the phenol is preferably carried out by using a fixed bed flow reactor with the packed organic high-molecular siloxane catalyst, which is a reactor for producing the bisphenol A. Preferably, the retention time in the case is ordinary 1 min to 15 hr, preferably 10 min to 5 hr, the molar ratio of the phenol to the acetone is 2-50, and the reaction time is 40-200 deg.C.

Abstract: PURPOSE:To prevent lowering of refrigerating capacity and occurrence of trouble of a compressor by surely detecting leakage of refrigerant. CONSTITUTION:A refrigeration device 10 is basically constituted of a compressor 12, a condenser 14, an expansion valve 16, and an evaporator. A high pressure switch 30 for sensing high pressure is inserted into a refrigerant delivery pipe 28 of the compressor 12.
