Study on Oxirane Cleavage Oxirane Ring Opening of Epoxidized Cardanol by Methanol and Characterization of Polyols

The impact of the main process variables temperature, catalyst concentration, agitation, ratio of content, time of reaction on the degration of the oxirane ring of epoxidizedcardanol by hydrogen active compound methanol when a homogeneous acid catalyst used, is analyzed in detail. Cashew Nut Shell Liquid CNSL , an agricultural by product abundantly available in tropical countries such as Vietnam, India, is one of the major and economical resources of naturally occurring phenols. Cardanol a by product of CNSL could be epoxidized by reacting carbon carbon double bonds of long unsaturated chain with peracids via the Prileshajev epoxidation process or the conventional process. This paper presents a simple and convenient method to oxirane ring opening of epoxidizedcardanol by methanol with preservation of p toluenesulfonic acid catalyst. The method uses mild reaction conditions low temperature of 400C – 500C and low pressure air pressure . The results shown that the oxirane ring opening of epoxidizedcardanol efficiency reacheres 76 at 500C, stirring rates 1500 rpm, 6 p toluenesulfonic acid catalyst and time of reaction 3h. The product of polyolcardanol is also characterized by FT IR, 1H NMR and 13C NMR.
