Title: Bromination of methyl group bonded to aromatic nucleus
Inventor: KOIKE KENGO
IPC: C07B39/00
Filed: 1989-02-23
Abstract: PURPOSE:To readily brominate a methyl group bonded to an aromatic nucleus, especially the methyl group bonded to an aromatic nucleus having an electron attracting group, at a low temperature in a good yield by reacting the methyl group bonded to the aromatic nucleus with a brominating agent in the presence of hydrogen peroxide when the raw material is brominated. CONSTITUTION:An aromatic compound having a methyl group bonded to the aromatic nucleus, preferably an aromatic compound having the methyl group and further at least one electron attracting group selected from NO2, halogen, CN, COOH and alkoxycarbonyl groups which are bonded to the aromatic nucleus, especially methyl benzene, is reacted with a brominating agent preferably bromine or hydrobromic acid, in the presence of hydrogen peroxide, if necessary, in an inert solvent to profitably brominate the methyl group. Since a by-product produced by the method is only water and the bromine atom of the brominating agent can be wholly reacted with the methyl group, the method does not require to capture hydrogen brominate by-produced by conventional methods and requires to use only a half of the brominating agent.

IPC: F01K25/10
Filed: 1983-03-18
Abstract: PURPOSE:To prevent intermediate medium charged in a Rankine cycle system from being discharged to the atmosphere upon periodical inspection, and as well to aim at recovering the medium, by recovering the medium, outside of the system by the pressure differential and the liquid head, and as well by charging the recovered medium in the system by the pressure differential. CONSTITUTION:During periodical inspection, when the evaporation of liquefied medium in a medium evaporator 12 is completed after a generator 14 is stopped, the supply of heat source to a heat exchange pipe 41 is ceased. When the condensation and liquefaction of evaporated medium in an LNG evaporator 10 are completed, a valve 57 is closed while a valve 58 is opened to allow LNG to pass through a heat exchange pipe 42 so that a medium recovering unit 16 and a tank 15 are cooled down, resulting in pressure drop. Therefore, liquid medium in the evaporator 10 is recovered to the tank 15 by the pressure differential between the evaporator 10 and the tank 15 and the liquid head. Meanwhile evaporated medium in another Rankine cycle system is extracted by closing a valve 61 and opening a valve 59 into a recovering unit 16, and is condensated and liquefied, being stored in a tank 15. Further, after completion of the inspection the liquefied medium in the tank 15 is charged into the evaporators by the pressure differential, and when the pressure is made uniform, the valve 57 is opened to recharge liquefied medium. After a limited liquid level is established, the valve 61 is closed.
