  • Process for the manufacture of high molecular weight aliphatic monocarboxylic acids
    Patent number: 3988331
    Abstract: By oxidation of straight-chained alpha-olefins having 16 to 70 carbon atoms with chromosulfuric acid, the corresponding aliphatic monocarboxylic acids are prepared without noteworthy degradation. The compounds obtained are suitable, inter alia, for making waxy esters or metal soaps which can be worked up into floor polishes or lubricants for plastic materials.
    Type: Grant
    Filed: April 4, 1975
    Date of Patent: October 26, 1976
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Helmut Korbanka, Werner Strassberger
  • Isomerization of C.sub.10 -C.sub.70 olefins of vinylidene structure to olefins of vinyl structure
    Patent number: 3940452
    Abstract: Olefins with vinyl groups are prepared by isomerization of olefins having vinylidene groups in the presence of a silicate having sheet structure, pumice or titanium dioxide as catalyst. The isomerization is carried out at a temperature of from 80 to 350.degree.C and the starting long chain vinylidene olefins have 10 to 70 carbon atoms. The olefins with vinyl groups obtained can be used to manufacture waxy carboxylic acids, sulfonic acids and epoxides.
