Scrubbing of Methyl chloride ( CH3Cl)
(OP)
In one of the reactions there is evolution of Methyl Chloride( CH3Cl). Is there a safe method to scrub the gas, and what should be the scrubbing solution?

RE: Scrubbing of Methyl chloride ( CH3Cl)
Scrub with water, then periodically do a fractional distillation to remove/recover the methyl chloride.
Methyl chloride: bp -24 C, solubility in water: 280 cc(gas)/100 grams water @ 16 C.
Also, absorption on granular activated carbon is probably a feasible alternative. Suggest that you check with GAC mfr., they will be eager to help.

But one must be careful: although it is moderately flammable by itself, this chemical can form explosive mixtures with air (VP at 25 Celsius:5.75 kPa). The published flammability limits at 25 Celsius and 760 mm Hg: 10.7-17.2 vol % in air. Besides, it is considered moderately toxic: OSHA's TLV is 50 ppm for an 8-hr TWA.
It can be hydrolyzed in boiling caustic (NaOH) solutions:
The acid is neutralized by the caustic, while methanol must be disposed of, probably by burning.
