    摘要: Alkoxy and aryloxy isothiocyanates are produced by the reaction of a haloformate and an alkali or alkaline earth metal thiocyanate in the presence of water and (i) a catalyst comprising a six membered mononuclear or ten membered fused polynuclear aromatic, heterocyclic compound having 1 or 2 nitrogen atoms as the only hetero atoms in the ring and (ii) a co-catalyst comprising an alkali metal or alkaline earth metal salt of an acid having a pKa of about 10.sup.-3 or below. The co-catalyst accelerates the reaction rate, increases product purity and reduces the adverse effects of impurities in certain grades of the thiocyanate reactants.
