Methyl Chloride → HCID 20341129, compound
Reaction equation
[CH3:1][Cl:2].B(F)(F)F.[CH3:7][C:8](=[CH2:10])[CH3:9]>>[CH3:9][C:8](=[CH2:7])[CH3:10].[CH2:1]([Cl:2])[C:8](=[CH2:7])[CH3:9]Participants
Procedure
About 10 parts by weight of fine, granular, hydrated silica and 20 parts by weight of methallyl chloride are mixed then agitated at ambient temperature for about 1 hour, thereby producing as mixture of poly (methyallyl chloride) polymer, methallyl chloride and hydrated silica. About 50 parts by weight of methyl chloride, containing a Friedel-Crafts catalyst, boron trifluoride, in the amount of 0.8 parts by weight, are added to said mixture and cooled to -40 degree to -100 degree F.; then this mixture is slowly added to a mixture containing about 100 parts by weight of isobutylene and 150 parts by weight of methyl chloride while agitating and keeping the temperature between -40 degree to -100 degree F., thereby producing poly (methallyl chloride isobutylene) copolymer.
