Title: Desulfurizing method for waste gas
Inventor: OGURI HARUO
IPC: C01F11/46
Filed: 1981-12-01
Abstract: PURPOSE:To increase the rate of dissolution of CaCO3 and to obtain a high rate of desulfurization in the case of circulating absorbing liquid dissolved therein with absorbents contg. CaCO3 and desulfurizing waste gases by bringing said liquid into contact with said gases by contg. gases in the absorbing liquid and aerating the same.

Title: Production of diacetylbiphenyl
Inventor: OGAWA YASUHITO
IPC: B01J31/04
Filed: 1993-07-07
Abstract: PURPOSE:To produce diacetylbiphenyl in high yield, as the formation of carboxylic acids is suppressed, by oxidizing an ethylbiphenyl with O2 in the presence of Co and Br in a solvent containing a lower aliphatic monocarboxylic acid. CONSTITUTION:In a solvent containing a lower aliphatic monocarboxylic acid (optimally using acetic acid in the single form), an ethylbiphenyl of the formula I (R is ethyl, acetyl) is oxidized with molecular oxygen in the presence of a catalyst containing cobalt and bromine to give diacetylbiphenyl of the formula II. As a catalyst, is preferably used cobalt acetate and sodium bromide. The process facilitates the post-treatments such as removal of the catalyst after the reaction. The diacetylbiphenyl of the formula II is useful as an intermediate for liquid-crystal compounds or a synthetic intermediate for high performance polymers.
