Its products were a series of characterization. Determination of hydroxyl value, such as understanding of the value generated hydroxyl content of the product in order to understand the reaction process in response to direction。 epoxy value determination is to understand the extent of the reaction remain in the epoxidation, a better understanding of the reaction extent and direction of reaction 。 infrared measurement is a better understanding of the reaction products of the functional group。 and by thermogravimetric analysis to understand the difference between products and reactants, and to determine whether reaction, but als
