Are there any new processes for m-chlorotoluene nowadays? How to improve the yield
This post was last edited by zhanyl628 on 2020-9-24 at 15:22. I also want to know what’s new and what’s old! I’m not sure if this \"method of synthesizing m-chlorotoluene using m-toluidine as a starting material, through diazotization and the Sandmeyer reaction\" is new or not
It seems that currently, there are mainly these two methods for producing m-chlorotoluene in production facilities: purifying m-chlorotoluene from mixed chlorotoluene, but sometimes the purity does not meet the required standards； Another method is to use m-toluidine to produce m-chlorotoluene; this approach allows for the production of high-purity m-chlorotoluene. Since the purity of m-nitrotoluene and m-toluidine can also reach 9.99%, the purity of m-chlorotoluene is likewise high. Are there any other economically viable “new methods”? Everyone, please feel free to share
Well, that’s the route I’m taking right now
The current synthesis route uses m-toluidine
The Germans did exactly that in 1934!
As far as I know, there are no new processes available for m-chlorotoluene at the moment; the so-called new processes that have been mentioned recently are merely theoretical, and there are significant difficulties in practical application that make it hard to control the process, so further optimization is needed. .
Is there a sedimentation and liquid separation step in the synthesis route of m-toluidine?
