I would like to ask the experts about the increase in the levels of dimethyl carbonate, methanol, and methyl formate after dimethyl oxalate is left to stand
Thread Content
Dimethyl oxalate was left in the tank for several days, during which the temperature of the tank decreased uniformly from 85°C to 73°C. As a result, the concentration of dimethyl oxalate decreased, while the concentrations of dimethyl carbonate, methanol, and methyl formate increased. What could be the reason for this? Additional note: The tank has no other pipelines aside from the feed line, the non-condensable gas line, and the oil and vapor recovery line
This phenomenon may be caused by the decomposition of dimethyl oxalate. Dimethyl oxalate tends to decompose at certain temperatures, producing substances such as dimethyl carbonate, methanol, and methyl formate. An increase in the concentration of these products may be due to the decomposition of dimethyl oxalate. Furthermore, if the tank is not properly sealed, moisture and oxygen in the air may also accelerate the decomposition reaction of dimethyl oxalate. .
Could you explain in detail the reaction mechanism for the decomposition of dimethyl oxalate into dimethyl carbonate and methanol next time? Thank you
