    摘要： A method for synthesis of lactic acid and its derivatives is provided. First, a mixture is prepared, which includes: at least one carbohydrate-containing raw material, at least one alcohol, at least one composite catalyst containing metal chloride(s) (MCln) and tin-containing compound(s), and at least one solvent, wherein M is selected from a group consisting of Li+, Na+ K+, Mg2+, Ca2+, Sr2+, Ga3+, In3+, Sb3+, Bi3+, Cr3+, Mn2+, Fe2+, Co2+, Ni2+, Zn2+, and n represents 1, 2 or 3. Then, the mixture is heated to obtain lactic acid and its derivatives. By using the above catalyst and method, it is capable of converting carbohydrate-containing raw material to lactic acid and its derivatives directly in a more efficient and economical way.

    摘要： A method of preparing antimony pentafluoride comprising converting antimony compounds to hydroxonium fluoroantimonates by reaction of the antimony compounds with fluorinating material, such as hydrogen fluoride, in the presence of an oxidizing agent, such as hydrogen peroxide, removing water from the reaction product to concentrate the hydroxonium fluoroantimonates and reacting the hydroxonium fluoroantimonates with carbonyl difluoride to produce antimony pentafluoride. In one embodiment the hydroxonium fluoroantimonates are prepared by recovering the antimony from spent alkylation catalyst comprising SbF.sub.5 deposited on silica. The silica can also be recovered and recycled to produce a remanufactured alkylation catalyst.

    摘要： Spent antimony halide catalysts resulting from the fluorination of chlorinated hydrocarbons and containing in the spent condition a mixture of antimony (III)- and antimony (V)-halides are regenerated by A. DISSOLVING THE SPENT CATALYST IN WATER TO FORM AN AQUEOUS ACIDIC SOLUTION THEREOF; B. ADDING A CONCENTRATED SOLUTION OF AMMONIA TO SAID AQUEOUS SOLUTION UNTIL THE SOLUTION IS SLIGHTLY ALKALINE AND MAINTAINING THE SOLUTION AT THE RESULTING INCREASED TEMPERATURE UNTIL THE ANTIMONY OXIDES ARE PRECIPITATED FROM THE SOLUTION, FORMING A SUSPENSION THEREIN; C. FILTERING OFF THE PRECIPITATE; D. DISSOLVING THE PRECIPITATE IN CONCENTRATED HYDROCHLORIC ACID; E. INTRODUCING SULFUROUS ACID, A SALT THEREOF OR SODIUM THIOSULFATE INTO THE SAID SOLUTION, WHILE ADDING A REDOX CATALYST IN CASE OF SULFUROUS ACID OR SALT THEREOF, SO AS TO CAUSE REDUCTION OF THE ANTIMONY (V)-chloride present in said mixture of antimony chlorides to antimony (III)-chloride; F. ADDING A CONCENTRATED AQUEOUS AMMONIA SOLUTION TO THE HYDROCHLORIC ACID SOLUTION TO PRECIPITATE THE ANTIMONY COMPOUND IN THE FORM OF ANTIMONY (III)-oxide or antimony (III)oxychloride; G. SEPARATING THE WEB PRECIPITATE FROM THE SOLUTION; H. DISSOLVING IT IN CONCENTRATED HYDROCHLORIC ACID, AND I. SUBJECTING THE HYDROCHLORIC ACID SOLUTION TO FRACTIONAL DISTILLATION TO OBTAIN ANTIMONY (III)-chloride which can be used as fresh catalyst in the above fluorination reaction. If the fluorine ion contents of the spent catalyst is not in excess of 1 percent, the reduction may be performed directly with the aqueous acidic solution of the catalyst without alkalizing the solution with ammonia solution and dissolving the precipitate in hydrochloric acid.
