Ethyl acetate
Thread Content
Ethyl acetate can be produced using acetic acid and ethanol, with a purity of up to 99.99%, but what causes the high acidity level? How to adjust it? Are there any operational experiences you’d like to discuss? For example: the adjustment of temperature, pressure, pressure difference, reflux ratio, etc. Thank you!
In my opinion, increasing the reflux in the deacidification tower, lowering the temperature of the esterification reactor appropriately, and optimizing the composition within that reactor can help reduce the acid content in the crude ester. Let’s listen to others’ insights together! :handshake
In my opinion, it might be due to too high a temperature during esterification in your esterification reactor, or poor temperature control in the distillation tower
The parameters of the deacidification tower and esterification reactor may not be optimized; they need to be adjusted again
High acidity is mainly related to the tower separation efficiency and the quality of operational control. If there is a deacidification tower, the reflux ratio can be appropriately increased or the acidity of the reactor broth can be kept low. If there is no deacidification tower, it is essential to ensure that the acidity of the crude ester is within the acceptable range.
