Synthetic line:
There are three main chemical synthesis lines
First is as follows
Methanol air oxidation method
This method can obtain propylene glycol methyl ether acetate through methanol air oxidation reaction. The specific steps are: to oxidize methanol and air under the action of a catalyst to obtain acetaldehyde and formic acid, and then to react acetaldehyde with methanol to obtain propylene glycol methyl ether acetate.
Second is as follows
Methanol formic acid esterification method
involves first reacting methanol with formic acid to obtain methanol formate, and then reacting propylene glycol with methanol formate to obtain propylene glycol methyl ether acetate. The specific steps are: heating methanol and formic acid under the action of a catalyst to obtain methanol formate, and then reacting methanol formate and propylene glycol under appropriate temperature and catalyst to obtain propylene glycol methyl ether acetate.
Third is as follows
Methanol methylacetone esterification method
This method involves reacting methanol with methylacetone to obtain methanol methylacetone alcohol, and then reacting methanol methylacetone alcohol with acetic acid to obtain propylene glycol methyl ether acetate. The specific steps are as follows: reacting methanol and methylacetone under the action of a catalyst to obtain methanol methylacetone alcohol, and then reacting methanol methylacetone alcohol and acetic acid under appropriate temperature and catalyst to obtain propylene glycol methyl ether acetate
