| Abstract: | Pinonic acid was prepared by ozonolysis of a-pinene obtained from turpentine. Ozonidation was carried out in inert solvent. The experimental results showed that acetic acid is a better solvent than others, m(α-pinene) : m(acetic acid) = 1 : 1; the temperature of ozonidation is below 10℃; the oxygenolysis temperature is 95℃; the oxygenolysis time is 2. 5 h; the oxygenolysis catalyst is a composite of manganese acetate and cobalt acetate, its dosage is 0.1% of α-pinene; the yield is >80%. |
