Abstract

Ethers of hydroxydihydrocitronellal, and its homologues, of formula RO-C(CH3)2-CH2-CH2-CH2-CH(CH3)-CH2-CHO (I) (where R is 1-4C alkyl, esp. Me or Et) are prepd. in good yield and sufficient purity for direct use in perfumery, by reacting citronellal or its homologues with a prim. or sec. amine or NH3, esp. at -10 to +40 degrees C; contacting the prod. with an alcohol ROH in the presence of a strong acid, esp. in at least equimolar concns.; neutralising the reaction compsn. with an alkaline reagent and sepg. (I) and pref. any acetal by-prod., pref. of formula RO-C(CH3)2-CH2-CH2-CH2-CH(CH3)-CH2-CH)OR)2 (II), esp. where R is Me. (II), which have a pleasant smell, are useful in perfumery or in insecticidal compsns.
