Patent number: 7884251Abstract: It is an object of the present invention to provide a specific industrial separation process that enables an alcohol to be separated out efficiently and stably for a prolonged period of time from a large amount of a low boiling point reaction mixture containing a by-produced alcohol when mass-producing aromatic carbonates on an industrial scale by subjecting a dialkyl carbonate and an aromatic monohydroxy compound to transesterification reaction in a reactive distillation column in which a catalyst is present. Although there have been various proposals regarding processes for the production of aromatic carbonates by means of a reactive distillation method, these have all been on a small scale and short operating time laboratory level, and there have been no disclosures whatsoever on a specific process or apparatus enabling mass production on an industrial scale to be carried out stably for a prolonged period of time.Type: GrantFiled: September 12, 2005Date of Patent: February 8, 2011Assignee: Asahi Kasei Chemicals CorporationInventors: Shinsuke Fukuoka, Hironori Miyaji, Hiroshi Hachiya, Kazuhiko Matsuzaki

Patent number: 4469900Abstract: A process is disclosed for separating closely-boiling chlorinated phenolic compounds from other chlorinated and unchlorinated phenolics by treating a mixture of the phenolics with a metal halide salt. The metal halide salt preferentially forms a complex with one of the phenolics over other related closely-boiling phenolics in the mixture. The preferentially-formed complex of one of the phenolics may then be isolated from the mixture and the complex decomposed to provide a product substantially enriched in, or substantially entirely composed of, one phenolic. The process is particularly suitable for resolving a mixture comprising phenol or cresol from their closely-boiling ortho-chlorinated derivatives, or a mixture of two isomeric chlorinated phenols or cresols or a mixture of closely-boiling mono- and dichlorinated phenols or cresols.Type: GrantFiled: January 4, 1984Date of Patent: September 4, 1984Assignee: Koppers Company, Inc.Inventor: Gerd Leston

Patent number: 4394526Abstract: Para-cresol is separated from a mixture comprising meta-cresol and various other methylated and ethylated phenols by preferentially complexing the para-cresol with one or more anhydrous or dehydrated inorganic salts selected from the group consisting of calcium bromide, lithium bromide, manganese bromide and magnesium chloride. The anhydrous inorganic salt is added to the phenolic mixture in an amount to give a mole ratio of salt to para-cresol in the mixture in the range of about 0.5 mole to one to about 1.5 mole to one. The para-cresol and salt form a complex and the complex is removed from the mixture of methylated and ethylated phenols. Then the complex is decomposed to recover the para-cresol and salt; the recovered salt may be recycled to complex with more para-cresol.Type: GrantFiled: September 26, 1980Date of Patent: July 19, 1983Assignee: Koppers Company, Inc.Inventor: Gerd Leston
