  • Catalyst prepared from tungsten hexafluoride and water
    Patent number: 4339350
    Abstract: A catalyst is prepared by reacting tungsten hexafluoride with water in a molar ratio of 2:1 to 20:1. This catalyst can be used to oligomerize 1-butene to produce synthetic hydrocarbon oils.

  • Synthetic hydrocarbon oligomers
    Patent number: 4334113
    Abstract: A synthetic hydrocarbon fluid is prepared by oligomerizing an olefin reactant in the presence of a catalyst prepared by reacting tungsten hexafluoride and water at a moderate temperature. For example, 1-butene is oligomerized at a temperature of about 40.degree. C. in the presence of a catalyst obtained by reacting tungsten hexafluoride and water in a four to one mol ratio. The liquid oligomer product is then hydrogenated to remove residual unsaturation.
    Type: Grant

  • Method for preparing synthetic hydrocarbon fluids
    Patent number: 4319065
    Abstract: A synthetic hydrocarbon fluid is prepared by oligomerizing an olefin reactant in the presence of a catalyst prepared by reacting tungsten hexafluoride and a branched-chain aliphatic alcohol at a moderate temperature. For example, 1-butene is oligomerized at a temperature of about 40.degree. C. in the presence of a catalyst obtained by reacting tungsten hexafluoride and isopropanol in a four to one mol ratio. The liquid oligomer product is then hydrogenated to remove residual unsaturation.

  • High fire point alkylaromatic insulating fluid
    Patent number: 4238343
    Abstract: A synthetic oil useful as an insulating fluid in electrical apparatus is prepared by reacting an aromatic compound with the oligomers of four to 12 carbon alpha-olefins containing predominantly at least about 30 carbon atoms up to about 60 carbon atoms. A synthetic insulating oil for electrical power transformers is prepared by reacting benzene in a 1:1 molar ratio with a tetramerpentamer mixture obtained by the oligomerization of 1-decene.
