Abstract: Terpinolene was synthesized from pinene by the catalysis of p-tolueresulfonic acid.The final content of terpinolene in product could be maintained 38.8 % and the yield of terpinolene was 39.9 %. Under the condition of 90 ℃,7 h,12.7 % catalyst, 36 % water,1.3 % emulsifier.The synthesis technigue and yield of product are all superior than those at home and abroad.
Key words: pinene;toluene-p-sulfonic acid;terpinolene
