The 12.9kg sulfuric acid dimethyl ester is slowly added to keep the reaction fluid reflux

About 3h Plus, continue to reflow 2-3h, cooling oil, with 5% sodium hydroxide solution washed, and then washed to ph 8, plus anhydrous potassium carbonate Dry. Remove the desiccant after decompression distillation, collect 120 ℃ (2.0kPa) fraction, that is, O-methoxy benzaldehyde.

Methylation reactions are also Can be carried out in solvent toluene, yield 60%.

 

Usage:

 2-Methoxycinnamic acid 

 is an organic synthetic intermediate for the production of spices and pharmaceuticals. O-methoxy basic formaldehyde can be used in production.
