| titleOfInvention | Process for the production of hexachloroacetone |
| abstract | The present invention relates to a process for the preparation of hexachloroacetone by the stepwise chlorination of acetone with chlorine gas. In the process according to the invention, a mixture of low-chlorinated acetones, which have 2 to 2.4 chlorine atoms per molecule on average, is first produced in a state that is absorbed in an organic liquid. The lower chlorinated acetones are further chlorinated to hexachloroacetone by adding chlorine gas to the liquid, which is heated up to about 150 ° C, using either a phosphine or a combination of a phosphine and an amine as the chlorination catalyst. Preferably, the acetone is chlorinated in the process according to the invention at the beginning by means of vapor phase contact reaction with excess chlorine at 70 to 100 ° C to an extent of 1,6- to 1,8-chloro ace ton, this in the organic liquid together with unreacted Chlorine is absorbed and undergoes further chlorination at 25 to 80 ° C to the extent of 2- to 2,5-chloroacetone. The process according to the invention gives hexachloroacetone in very good yield with very low levels of low-chlorinated acetones. |
