| Abstract: | Using a silanized basic anion exchange resin as a catalyst, 2,2 dimethylolpropionaldehyde was advantageously obtained through the aldol reaction of formaldehyde and propanal in a fixed bed reactor. Then taking hydrogen peroxide as an oxidant, 2,2 dimethylolpropionic acid was effectively prepared with a solid acid catalyst. The experimental results were explained and discussed theoretically. |
