摘要 |
<p>Process for preparing HCFC-123 with a content of olefins lower than 10 ppm and very small amounts of HCFC-123a and 123b by dismutation of HCFC-124 in gaseous phase by contact with a catalyst which essentially consists of three valence chromium oxide supported on aluminum fluoride, at temperatures in the range 150 DEG -260 DEG C, and with contact times between 5-25 sec.</p> |
