On March 30, 1967, Hackmann, Johannes T.; Yates, John; Willcox, Trevor J.; Haken, Pieter T.; Wood, Derek Alexander published a patent.Recommanded Product: 15258-72-7 The title of the patent was 2,6-Dichlorobenzal chloride, 2,6-dichlorobenzyl chloride. And the patent contained the following:
2-Nitro-6-chlorotoluene (I) is treated with Cl at 160-85° and the H2O formed removed continuously to give the title compounds Thus, 500 g. I is heated and Cl is introduced into the molten mass. The aqueous phase containing HCl and HNO3 is removed continuously. At a reaction temperature of 180°, Cl introduction of 0.17 mole/hr./mole I, and 35 hrs. reaction time, 62% 2,6-dichlorobenzal chloride and 15% 2,6-dichlorobenzyl chloride are obtained. The experimental process involved the reaction of 1-Chloro-2-(chloromethyl)-3-nitrobenzene(cas: 15258-72-7).Recommanded Product: 15258-72-7
1-Chloro-2-(chloromethyl)-3-nitrobenzene(cas:15258-72-7) belongs to chlorides. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst. Recommanded Product: 15258-72-7
