Title: Production of aromatic carboxylic acid
Inventor: MORI KOJI
IPC: C07C51/255
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce the production cost of an aromatic carboxylic acid such as terephthalic acid by setting the oxidation reaction temperature to a relatively low level, i.e., 140-190 deg.C to prevent the combustion or decomposition loss of acetic acid used as a reaction solvent, recovering the heat generated by the oxidation reaction in the form of steam in the distillation separation of water generated by the reaction from acetic acid for recycling the acetic acid solvent used in the reaction and using a part of the recovered heat as a heat-source for the distillation separation process. SOLUTION: An alkylaromatic hydrocarbon is oxidized in liquid phase with a gas containing molecular oxygen in the presence of a catalyst in a lower aliphatic carboxylic acid, the mixture of water generated by the oxidation and the lower aliphatic carboxylic acid is separated into the components by distillation and the separated lower aliphatic carboxylic acid is reused in the reaction. In the above aromatic carboxylic acid production process, the oxidation reaction is carried out at 140-190 deg.C, the heat generated by the reaction is recovered and reused as a heat source of the distillation separation process and azeotropic distillation is used as the distillation separation process.

Filed: 1987-12-28
Abstract: PURPOSE:To improve the operability of spinning and to contrive enhancement of water permeability while maintaining fractionation performance by utilizing triethylene glycol dimethyl ether as the solvent of spinning raw liquid consisting of a polysulfone-base polymer, spinning and discharging the mixture into an aq. soln.
