Abstract
Inventia se refera la sinteza unor intermediari reactivi bifunctionali, de tip epoxiclorhidrina sau diclorhidrina cu grupe de sare cuaternara, prin aditia aminelor secundare si respectiv a clorhidratilor aminelor secundare si tertiare la epihalohidrine, în mediu de alcool etilic. Produsii de reatcie rezuta ca solutii în alcool etilic sau în epihalohidrine din care se pot izola prin îndepartarea solventului.The invention relates to the synthesis of bifunctional reactive intermediates such as epoxychlorohydrochloride or diclorohydrin with quaternary salt groups by the addition of secondary amines and secondary and tertiary amine hydrochloride to epihalohydrins, respectively, in ethyl alcohol medium. Reaction products are solutions in ethyl alcohol or epihalohydrin from which they can be isolated by removing the solvent.
