Treatment of **dimethyl etherification waste salts
Thread Content
A large amount of sodium chloride is generated during the production of p-aminobenzyl ether; this sodium chloride precipitates during the etherification process. However, it contains a small amount of organic substances. It is necessary to find a way to separate these organic substances from the sodium chloride, and the purity of the sodium chloride after separation must meet the requirements for electrolysis. Can it be removed by washing with methanol? Are there any good alternatives to burning? Seek guidance from experts……
Evaporation can also be used for separation.
Organic compounds have a boiling point of 269 degrees Celsius; the solid salts have already crystallized. Is it possible to proceed with evaporation? Are there any successful cases?
Help, experts! The holiday is over now. I’m in need of help – the boss needs it urgently. It’s really frustrating; I’m in tears……
Adsorption resins can remove organic substances from brine, and sometimes solid acids can be used as a substitute for liquid acids
Sodium chloride is inexpensive in itself, and the cost of purification is too high
