trans-Cinnamic acid Use and Manufacturing
The preparation method is to add benzaldehyde, acetic anhydride and anhydrous sodium acetate into the reactor, heat at 180°C for 8 hours, then cool to 80-100°C, pour it into water and perform steam distillation to remove unreacted benzaldehyde After distillation, add proper amount of hydrochloric acid to the solution to acidify, and the product will precipitate.
Determination of uranium and vanadium, separation of thorium, and manufacture of cinnamate. The standard of double bond determination by organic microanalysis.
