Abstract
小四号,Times New Roman行距固定值:20镑
A procedure is 1S,2S,3R,5S-(+)-2,3-Pinanediol is significant for humans as a kind of anticancer medicine, of which the demand and price are soaring year by year. On the basis of the chemical synthesis method using potassium permanganate as oxidant, the synthesis of 1S,2S,3R,5S-(+)-2,3-pinanediol by electrochemical oxidation was also explored. It constitutes a electrochemistry system, with 1S-(+)-α-pinene as raw material, tert-butyl alcohol as cosolvent, sodium sulfate as supporting electrolyte, and with ruthenium coated titanium as anode, stainless as cathode. Seeing about the affect of pH, voltage, electrolysis time and whether or not to add membrane to the yield producing 1S,2S,3R, 5S-(+)-2,3-pinanediol. The results showed that the electrochemical synthesis pinanediol is feasible. And at the state of neutral electrolyte without membrane, voltage 12v, reaction time 10h, it could obtain the highest yeild.
