The invention pertains to a process for preparing an arylpoly(oxyalkyl)compound, wherein the process involves reacting a phenol with a halohydrin, and reacting the reaction product with an amino alkyl halide. The invention seeks to provide a less hazardous alternative to conventional preparation processes where arylpoly(oxyalkyl)compounds are made starting from an extremely toxic and hazardous dihalogeno-polyalkylene ether. The preferred arylpoly(oxyalkyl)compound is benzethonium chloride.
这项发明涉及一种制备芳基聚(氧烷基)化合物的过程,其中该过程包括将酚与卤水合物反应,然后将反应产物与氨基卤代烷反应。该发明旨在提供一种较少危险的替代方案,用于传统制备过程中,芳基聚(氧烷基)化合物是从一种极具毒性和危险性的二卤代聚烷基醚开始制备的。首选的芳基聚(氧烷基)化合物是苯托溴铵盐。
