Abstract
Un proceso para preparar 2-mercaptotiazol haciendo reaccionar una sal soluble en agua de ácido ditiocarbámico con 2-haloacetaldehido donde el 2-haloacetaldehido se agrega a una suspension de la sal de ácido ditiocarbámico en forma solida enu n diluyente miscible con agua en el cual la sal essubstancialmente insoluble, o el 2-haloacetaldehido y una solucion de sal de ácido ditiocarbámico son alimentadas en forma separada y simultánea avelocidades de adicion substancialmenteequimolares a un recipiente de reaccion que contiene un diluyente miscible con agua en el cual la sal essubstancialmente insoluble o una sal de amonio de un ácido ditiocarbámico se prepara por reaccion de un amoníaco con disulfuro de carbono enpresenciade u na amina terciaria con pkb mayor que el del amoníaco que es trialquilamina.A process for preparing 2-mercaptothiazole by reacting a water-soluble salt of dithiocarbamic acid with 2-haloacetaldehyde where 2-haloacetaldehyde is added to a suspension of the dithiocarbamic acid salt in solid form in a water-miscible diluent in which the Salt is substantially insoluble, or 2-haloacetaldehyde and a solution of dithiocarbamic acid salt are fed separately and simultaneously at substantially equimolar addition rates to a reaction vessel containing a water-miscible diluent in which the salt is substantially insoluble or a salt of ammonia from a dithiocarbamic acid is prepared by reacting an ammonia with carbon disulfide in the presence of a tertiary amine with pkb higher than that of the ammonia which is trialkylamine.
