Several problems in the production of glycerol formal

2009-02-05View Original

Thread Content

In the process of producing glycerol formal, occasionally the content of glycerol formal does not reach 99%. However, after discharging the system residue and refeeding, it can reach more than 99%, and the process parameters during the period have not changed. In addition, in the process of analyzing components by chromatography, it is impossible to determine the component of the last chromatographic peak. (Using the reaction of glycerin and formaldehyde to obtain more than 90% glycerol formal) Please help analyze it if you know it!
