NEW MATERIAL:The titled compound of formula I (R is 2-10C alkyl, 2-10C alkenyl, aryl). EXAMPLE:3-Methyl-3-butenyl acetate. USE:A durable perfumery or scent modifier for soap, detergent, cosmetic or sanitary goods. PREPARATION:The reaction of 3-methyl-3-buten-1-ol of formula I with a carboxylic acid or its reactive derivative of (RCO)nX (X is hydroxyl, halogen, oxygen atom, where when X is hydroxyl or halogen atom, n is 1 and, when X is oxygen atom, n is 2), preferably in an amount of 1-3 times the molar quantity of the butenol is conducted, when necessary, in the presence of a catalyst such as sulfuric acid, e.g., at -10-150 deg.C. |
