IN A PROCESS OF MAKING A LOWER FATTY ACID ESTER OF A NONADIENE CARBINOL SELECTED FROM THE GROUP CONSISTING OF GERANIOL, NEROL AND LINALOOL WHEREIN A HALIDE SELECTED FROM THE GROUP CONSISTING OF GERANYL, NERYL AND LINALYL CHLORIDES AND BROMIDES IS HEATED WITH AN ALKALI METAL SALT OF A LOWER FATTY ACID AT AN ELEVATED TEMPERATURE WHEREBY THE FATTY ACID ACYLOXY GROUP IS CAUSED TO REPLACE THE HALOGEN, THE STEP WHICH COMPRISES MAKING SAID HALIDE BY TREATING MYRCENE WITH A SUBSTANTIALLY ANHYDROUS HYDROGEN HALIDE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN CHLORIDE AND HYDROGEN BROMIDE AT A TEMPERATURE OF FROM 0* TO 50* C. AND THEREBY EFFECTING PREFERENTIAL ADDITION REACTION OF SAID HYDROGEN HALIDE WITH SAID MYCRENE AT ONLY ONE DOUBLE BOND LOCATED IN THE CONJUGATED DIENE PORTION OF THE MYRCENE, THE AMOUNT OF SIAD HYDROGEN HALIDE COMBINING WITH SAID MYRCENE RANGING FROM 0.75 TO 1.25 MOLS PER MOL OF MYRCENE.
