| 摘要 |
An improved process for the preparation of primary terpenoid alcohols, e.g. 6,7-dihydrogeraniol and phytol, and of their esters with formic acid. The terpenoid formates are obtained very advantageously by reacting the corresponding tert.-vinylcarbinols with more than 2 moles, per mole of vinylcarbinol, of aqueous formic acid of more than 70 percent strength by weight, or with anhydrous formic acid, at from 5 DEG to 100 DEG C. The primary terpenoid alcohols themselves are obtained from their formates by trans-esterification with a low-boiling alcohol in the presence of a catalytic amount of a strong base. The products are valuable compounds. For example, 6,7-dihydrogeraniol is used as a scent and phytol is used as a perfume fixative and as a starting material for the synthesis of naturally occurring materials. |
