Description
Известные производственные способы получени бензальхлорида и бензотрихлорида и их хлорпроизводных хлорированием ароматических соединений с боковой метильной группой газообразным хлором в присутствии катализаторов пероксидиого тииа требуют продолжител1 -ного времеии и сопровождаютс потер ми пероксида в результате его распада.Known production methods for the production of benzalchloride and benzotrichloride and their chlorine derivatives by chlorinating aromatics with a methyl side group with chlorine gas in the presence of peroxidium thio catalysts require a long time and loss of peroxide as a result of its decomposition.
Описываемый способ отличаетс тем, что, с целью ускорени процесса и предотвращ.ени распада пероксида, реакцию ведут с добавкой ароматических альдегидов и при темиературе не выше 110°.The described method is characterized in that, in order to speed up the process and prevent peroxide decomposition, the reaction is carried out with the addition of aromatic aldehydes and at a temperature not higher than 110 °.
