    摘要： Compounds of the structure ##STR1## wherein X is --F or Cl and each R is independently --H, --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3, --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 or M where M is an alkali metal, an alkaline earth metal, ammonium or a quaternary ammonium are disclosed. The above compounds are prepared by treating a compound of the structure ##STR2## where each R.sup.1 is independently --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3 or --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 ; or ##STR3## with a strong protic acid, followed, as desired, by base hydrolysis to form carboxylate salts (R.dbd.M).

    摘要翻译： 其中X是-F或Cl并且每个R独立地是-H，-CH 3，-C 2 H 5，-CH 2 CH 2 CH 3，-CH 2 CH 2 CH 2 CH 3或M的结构化合物，其中M是碱金属，碱土金属，铵或 公开季铵。 上述化合物通过处理结构的化合物制备，其中每个R 1独立地是-CH 3，-C 2 H 5，-CH 2 CH 2 CH 3或-CH 2 CH 2 CH 2 CH 3; 或与强质子酸反应，然后根据需要通过碱水解形成羧酸盐（R = M）。

    摘要： CHLOROSULFATES OF THE FORMULA:

    R(OSO2CL)N

    WHEREIN N IS 1 OR 2; R MAY BE AN OPEN CHAIN YZ-PERHALOALKYL GROUP WHEN N IS 1 OR AN OPEN-CHAIN YZ-PERHALOALKYLENE GROUP CONTAINING AT LEAST THREE CARBON ATOMS WHEN N IS 2, WHEREIN Y AND Z ARE SUBSTITUENTS ON THE R MOIETY AND ARE THE SAME OR DIFFERENT ELECTRONEGATIVE GROUPS; MAY BE PREPARED BY REACTING HYPOCHLORITES OF THE FORMULA R-(OCI)N WHEREIN R AND N ARE AS DEFINED ABOVE, WITH SULFUR DIOXIDE AT A TEMPERATURE BELOW ABOUT 0*C. THE CHLOROSULFATE PRODUCTS ARE A KNOWN CLASS OF COMPOUNDS AND ARE USEFUL AS INTERMEDIATES FOR THE PREPARATION OF HALOGENATED KETONES, CARBOXYLIC ACIDS, ESTERS, THIOLESTERS, AMIDES, ALDEHYDES AND POLYESTERS.
