Experimental study of refining solanesol from crude solanesol by saponification

The saponification （30%） were studied in this work conditions of crude solanesol The results showed the content of solanesol arrived to 41.9%; the optimal conditions of solanesol saponification were the saponification time of 3 hours, the saponification temperature about 45℃, amount of 2.5g NaOH and amount of 30mL C2H5OH. NEWTON-LAPUSON method was applied to iterate. The correlative equations provide an effective basis for further research of refining solanesol.
