摘要： In a method for acetylene hydrochlorination to vinyl chloride catalyzed by ultra-low content aurum-based material, a nitrogen-modified activated carbon support is obtained by using 1,10-phenanthroline as a modifier. A trace amount of aurum is used as a main active component and an organic solvent with a low polarity and a low boiling point, isopropanol, is used as a solvent. An ultra-low content of aurum-based catalyst with the aurum loading amount of 0.01 wt % using the above nitrogen-modified activated carbon as a support is prepared by improving the synthesis procedure, and the efficiency of the catalyst is significantly improved. The catalyst has high activity and vinyl chloride selectivity for acetylene hydrochlorination to vinyl chloride, which is low cost, no mercury pollution, simple in preparation process and expansibility, and has great industrial application value.

摘要： The invention relates to a process to produce HCFC-244bb from HCFO-1233xf wherein, in one embodiment, co-feed species HFC-245cb is added to the reaction at a pressure of at least about 100 psig; and in another embodiment it is added to maintain a mole ratio of HFC-245cb to HCFO-1233xf of between about 0.005:1 to about 1:1. The HFC-245cb may be added as recycled by-product of the reaction and/or added as fresh feed. The HFC-245cb provides elevated pressures to the reaction thereby facilitating reactor operation, mixing and HCFC-244bb product removal. Other co-feed species are also disclosed.
