Process for the production of isotiocianatos n - alqu (EN) u00f3xi (ouarilu00f3xi) cabonila and its derivatives in the presence of catalyst of N, N - dialquilarilamina
Invention patent: b "process for the production of isotiocianatos n - alqu (EN) u00f3xi (or arilu00f3xi) cabonila and its derivatives in the presence of catalyst of N, N - dialquilarilamina" d .The present invention provides a process for the production of isothiocyanate derivatives of b n d - alqu (EN) u00f3xi (or arilu00f3xi) by the reaction of a carbonyl haloformiato with a thiocyanate, in the presence of U.M aqueous solvent or an organic solvent and a catalytic amount of a b N,N d - dialqu (EN) ilarilamina to produce an intermediate isothiocyanate b n d - alcu00f3xi (or arilu00f3xi) carbonyl where the intermediate product is converted to a derivative of isothiocyanate b n d - alqu (EN) u00f3xi (or arilu00f3xi) carbonyl of high purity and production.The invention also provides a process for the production of isothiocyanate b n d - alqu (EN) u00f3xi (or arilu00f3xi) by the reaction of a carbonyl haloformiato with a thiocyanate, in the presence of a solvent aquosOr an organic solvent and a catalytic amount of a b N, n d - dialqu (EN) ilarilamina.
