PROCESS FOR MONOMETHYLATION OF NITROGEN CONTAINING HETEROCYCLIC COMPOUNDS

PROCESS FOR MONOMETHYLATION OF NITROGEN CONTAINING HETEROCYCLIC COMPOUNDS

Monomethylation of heterocyclic nitrogen compounds with at least one nitrogen attached to hydrogen by reacting with dimethyl carbonate at 100 - 200[deg]C and 0.93 - 1.07.105>Pa, the methanol formed being continuously removed.
