| 摘要 |
Myrcene is reacted with hydrogen chloride or bromide to obtain geranyl, neryl and linalyl halides at from -30 DEG to +50 DEG C. from sub-atmospheric pressure to 100 p.s.i.g. in the presence of the corresponding cupric halide or a cupric compound which forms the halide by reaction with HC1 or HBr, the hydrogen halide being charged at an average rate of 0.01-30 moles per hour per mole of myrcene originally charged, said rate being adjusted so as to maintain a 0-10% concentration of 2-methyl-2-halo-6-methylene-octane-7. Specified cupric compounds are the chloride, bromide, carbonate, oxide, formate, acetate, sulphate, nitrate, oleate, resinate and naphthenate. Specifications 896,262 and 919,321 are referred to. |
