Abstract
A method of making a synthetic lime mix having the fragrance of steam distilled lime oil comprising the steps of refluxing a mixture of citral or a citral containing oil and water in the presence of an acid catalyst, distilling the refluxed mixture and recovering a reaction product containing 1-methyl-1,3-cyclohexadiene.
Claims4
A method of making a synthetic lime mix having the fragrance of steam distilled natural lime oil comprising the steps of refluxing a mixture of (A) citral or a citral-containing oil selected from the group consisting of lemongrass oil, Eucalyptus staigeriana and Litsea cubeba and (B) an acid selected from the group consisting of mineral acids and organic carboxylic acids and water for a period of from 1 to 3 hours, said acid being a catalyst and being present in a weight ratio of citral to acid of from about 1:1 to 20:1 which is effective to adjust the pH of said mixture to between 1.0 and 2.0;
- distilling the refluxed mixture and recovering from the distilled mixture a reaction-product consisting essentially of a major amount of terpene hydrocarbons and minor amounts of oxygen-containing compounds and 1-methyl-1,3-cyclohexadiene.
