Paragraph 0018; 0019; 0020; 0021; 0022, (2017/08/25)
The invention relates to the field of fine chemistry, and concretely relates to a thiogeraniol preparation method. The method comprises the following steps: carrying out a reaction on a raw material thiogeraniol with triphenyl phosphine in a solvent carbon tetrachloride, carrying out a reaction on the above obtained reaction product 1 with thiourea in a solvent anhydrous ethanol, carrying out a reaction on the above obtained reaction product 2 and p-toluenesulfonic acid to form a salt, and decomposing the salt to obtain a final product. The method has the advantages of avoiding of generation of isomers due to prevention of high-temperature distillation purification in a key purification step, easiness in obtaining of the raw material, low cost, short synthesis short, easiness in realization of reaction conditions, convenient and easy purification process, high yield, and realization of obtaining of highly-pure thiogeraniol.
