| titleOfInvention | Catalyst and the application thereof of difluoroethanol is prepared for vapor phase method |
| abstract | The present invention relates to catalyst and the application thereof of preparing difluoroethanol for vapor phase method, is there is the higher problem of selective lower, contaminated environment and catalyst reduction and reaction temperature to solve the existing catalyst for the preparation of difluoroethanol.The feature of involved catalyst is, the presoma of this catalyst is the mixture of the soluble-salt of copper, the soluble-salt of lanthanum, ZSM-5 molecular sieve and Ludox, and described presoma must be used for the catalyst that vapor phase method prepares difluoroethanol after roasting.Involved application comprises: under hydrogen catalyst pre-reduction and normal pressure, 180 ~ 200 DEG C of conditions, gas phase difluoro acetate and the hydrogen stream catalyst reaction after prereduction prepares difluoroethanol.Catalyst of the present invention is not containing Cr element, for environmentally friendly catalyst and selective height, and when utilizing catalyst preparing difluoroethanol of the present invention, the pre-reduction temperature of catalyst and reaction temperature are all lower, wherein the reduction temperature of catalyst only needs 210 DEG C ~ 240 DEG C, and reaction temperature is 180-200 DEG C. |
