More Information
Summary:The invention discloses a preparation method of bis-terpane-3,8-diol. According to the preparation method, eucalyptus citriodora oil and/or citronellal are/is taken as raw materials, immobilized quaternary ammonium salt is taken as a catalyst, and a cyclization hydration reaction is conducted in an acidic aqueous solution to prepare the bis-terpane-3,8-diol. The preparation method has the advantages of mild reaction conditions, short reaction time, and easy operation. The purity of prepared PMD can reach 80-98%; reaction products are easy in oil-water separation; the acidic aqueous solution can be recycled, so that the quantity of discharged waste water is small; the used raw materials are wide in source; the use amount of the catalyst is small; the raw materials are cheap and easy to obtain.
