Abstract
Linalool oxide is prepared by epoxidation of citral to citral diepoxid, reacting the diepoxide with hydrazine and treating the reaction product with acid and/or distilling the reaction product. The epoxidation can be effected in one stage, using an organic per-acid, or by first forming citral a ,b -monoepoxide by treatment with an alkaline solution of hydrogen peroxide in an alcohol and converting the monoepoxide to the diepoxide by treatment with an organic peracid. The reaction of the diepoxide and hydrazine is preferably carried out using a solution of hydrazine hydrate in an organic solvent and in the presence of an acid catalyst, which may be an organic or mineral acid or a cation exchange resin. The same acids may be used in the after treatment of the reaction product. Some linalool may be obtained as a by-product.
