    Abstract: Methyl m-nitrobenzoate is prepared by a process in which an isomer mixture is treated with from 10 to 1000% by weight of water in the presence of from 0.05 to 20% by weight of an emulsifier, the percentages being based on the weight of the isomer mixture, (a) in a first stage at from 55 DEG to 100 DEG C. and a pH from 2 to 8 and then (b) in a second stage at from 10 DEG to 40 DEG C. and a pH of not less than 9. The methyl m-nitrobenzoate obtainable by the process of the invention is a useful starting material for the preparation of dyes and crop protection agents.

    Abstract: 1467386 o-Benzyl toluenes BASF AG 16 July 1974 [17 July 1973] 31396/74 Heading C5E [Also in Division C2] o-Benzyl toluenes of the formula I wherein R 1 are H or halogen, R 2 are H, halogen or an aliphatic or aromatic radical are prepared by reacting an o-xylyl halide of the formula II with a benzene compound of the formula III in the presence of BF 3 activity and associated oxygen-containing acid activity. The BF 3 activity may be provided by free BF 3 or an adduct thereof. The oxygen-containing acid activity may be provided by any acid including a Lewis acid having one or more oxygen atoms in the molecule or in the complex if in adduct form. Consequently both activities may be provided by complexes of BF 3 with water, ethanol, phosphoric acid or ethers. Certain compounds of the formula I are claimed per se namely when (i) R 1 are H or halogen and R 2 are all aromatic; or (ii) one R 1 is halogen, and the other R 1 are H or halogen and R 2 are H or aliphatic; or (iii) all R 1 are H, one R 2 is aromatic, one R 2 is H, halogen or aliphatic and the other R 2 are H, halogen, aliphatic or aromatic; or (iv) all R 1 are H, one R 2 is halogen, one R 2 is aliphatic and the remaining R 2 are H, halogen or aliphatic. Hydrocarbons prepared in the examples are: o-benzyltoluene; 2,3 1 ,4 1 -trimethyldiphenyl methane; and 2-methyl-4 1 -phenyl-diphenyl methane.
