  • Process for halogenation of conjugated dienes to dihalogenated butene products
    Patent number: 3932543
    Abstract: In the process for halogenation of conjugated dienes with elemental halogen under halogenation conditions, the improvement for obtaining increased yield of dihalogenated butene products comprising forming the reaction mixture with a dipolar aprotic solvent vehicle resistant to halogenation under such conditions in the proportion of about 0.05-10 moles per mole of said diene. The invention has particular application in the chlorination of isoprene to 1,4-dichloro-2-methyl-2-butene and 1,2-dichloro-2-methyl-3-butene.

  • Process for preparing unsaturated terpene alcohols
    Patent number: 3932539
    Abstract: An improved process for the preparation of unsaturated terpene alcohols such as myrcenol and cis and trans ocimenol is described. Acyclic terpene allylic halides are reacted with a tertiary amine of the formula hereinafter described to form the corresponding quaternary ammonium salt which is then acidified to remove the ethylenic unsaturation between the 6th and 7th carbon atom and adding a hydroxy substituent on the 7th carbon atom of the terpene halide salt. The hydrated terpene ammonium halide salt is made neutral and thermally decomposed into the unsaturated terpene alcohols. Myrcenol and ocimenol cis and trans are useful for their fragrance and aroma in perfumery and cosmetic manufacture.
