专利号:US-5493054-A 优先权日:1992-01-29 标题:Process for the synthesis of acid halides and reactants useful for its implementation 发明人:FORAT GERARD; GILBERT LAURENT 权利人:RHONE POULENC CHIMIE 摘要:The subject of the present invention is a new catalytic system and a process for the synthesis of acid halides, especially from haloforms. This process for halogenating by means of a haloform is characterized by the use of a metal chloride, advantageously trivalent, as a catalyst, the solubility of which in the reaction mixture is at least equal to one millimole, preferably 1/100 mole per liter, and the metal chloride also being at least half, advantageously two-thirds and preferably three-quarters in the dissolved state.
