How is chloroethane recovered in the production of diethyl phosphite
Thread Content
Dear colleagues: I am currently organizing the production process for diethyl phosphite. I’m not sure how to recover the chloroethane generated as a by-product of this reaction; I would appreciate your guidance on this matter. Thank you!
During the reaction of phosphorus trichloride with ethanol to produce diethyl phosphite, chloroethane is generated; hydrogen chloride is also produced in this process. Hydrogen chloride can be easily recovered, but it is not clear how chloroethane can be recovered. If anyone has done this process, please let me know the general steps for recycling it. Thank you for following.
Most of what is generated during the production process will escape as gas; given its high concentration and large flow rate, recovery can be considered, otherwise, measures must be taken to treat the exhaust gases before they are released into the atmosphere.
The boiling point is 12.3 degrees; there is also non-condensable hydrogen chloride gas that needs to be recovered through condensation. To what temperature does it need to be cooled?
