Aluminium Chloride as a Catalyst of Hydrogen Interchange

Nature volume 135, page 267 (16 February 1935) | Download Citation



THE Friedel Crafts reaction: suggests the use of AlC13 as a catalyst for the interchange of hydrogen between benzene and hydrogen chloride. We have found this expectation confirmed in the following experiments: 0.5 gm. of AlC13 was brought into contact, for three hours, in a vessel of about 100 c.c. capacity, with a mixture of ordinary benzene and hydrogen chloride containing 13.4 per cent D, the temperature in two runs being 25° and 50° respectively.
