Problems solved by technology
[0002] The waste gas of 2-cyano-4'-bromomethylbiphenyl contains a large amount of organic solvents. The traditional waste gas treatment process directly treats the organic solvents and waste gas together and then discharges them cleanly, resulting in a great waste of resources and also to the waste gas. The processing of the
