Abstract
PURPOSE: To prepare a formic acid ester useful as perfumery and its intermediate, without producing terpene alcohols having undesirable effect to the perfume of the product, by reducing terpene formic acid esters in the presence of an organic acid, thereby preventing the hydrolysis during the reduction.
CONSTITUTION: A terpene formic acid ester such as a compound of formula I or II (R1 is H or methyl; R2 is group III or alkyl having the group III), especially dehydrolinalyl formate, linalyl formate, etc. is reduced under neutral or weakly acidic conditions. The control of pH is carried out by adding an organic aicd, pref. an aliphatic monobasic acid, especially acetic acid, to the system. The amount of the organic acid is 0.1W10wt%, pref. 0.2W3wt% of the terpene formic acid ester. If the organic acid is not present, the formic acid ester is hydrolyzed with formic acid produced by the reducing reaction of the terpene formic acid ester. The addition of the organic acid prevents the hydrolysis, and accordingly the by-production of terpene alcohol.
