Methyl chloride grades available

Methyl chloride is available for commercial and industrial use in various grades having much the... 

A mixed ether, hydroxypropyl-methylcellulose, is also available. This is prepared by treating alkali cellulose with a mixture of methyl chloride and propylene oxide. Commercial grades of the polymer generally have a methoxy content of about 30% and a hydroxypropoxy content of about 5—10%. The mixed ether has increased organo-solubility and thermoplasticity over the methylcellulose counterparts. 

Materials. 2, 3-dinitroaniline (8), -methyl-N, N-dimethyl-aniline (9), p-chloro-N, N-dimethylaniline (9), p-nitro-N, N-dimethylaniline (1 ), N-methyl-p-toluidine (11), p-chloro-N-methylaniline (11), N, 2, 4-trinitroaniline (12), 2, 4-dinitro-N-methylaniline (13), 2, 4-dinitro-N, N-dimethylaniline (13) and N, 2, 4-trinitro-N-methylaniline (14) were prepared by known methods. Spectroscopic grade nitromethane and methylene chloride were dried using a molecular sieve. The other substrates were either available from related studies or were purchased and purified by standard methods.
