***Plant residual waste treatment
Thread Content
***The factory generates large amounts of residue, which contains high levels of *** and m-***benzene. Small enterprises take this residue to extract *** from it again; the remaining residue is mainly m-***benzene. M-***benzene is highly toxic and also an expensive intermediate. So, how can it be extracted and utilized effectively?
Reply 1# A-king: What is the content of dinitro in the residue?
Reply to 2# monoyu: It has been extracted; the remaining content of dinitro in the residue is over 70%
It’s great for producing diamines!

A mild alkaline wash will do; hot water can dissolve it. Toxicity is high in summer, but it’s okay in winter.
How to filter it – dissolution is a problem; in winter it becomes a very hard and solid substance
Reply to 7# wumian: Theoretically, it can be dissolved by heating, but this method is only suitable for laboratory use. In industrial settings, solvents are used, and the dissolution process is slow due to the large volume; only partial dissolution occurs slowly
Reply to 8# A-king: If this thing is crushed, it could be dangerous too; it’s not easy to do that
Reply to 10# monoyu: It needs to be broken into small pieces first before a solvent can be added to dissolve it by heating; otherwise, how long will it take for such a hard substance to dissolve?
