Patent GB-589466-A (GB)
Title: Improvements in or relating to the production of aryl derivatives of trichloroethane
IPC: C07C17/26
Filed: 1945-03-21
Abstract: In the preparation of trichloromethyl-diaryl methanes from the mixture resulting from the condensation in aqueous sulphuric acid of chloral or a compound yielding chloral in the presence of sulphuric acid, and an aromatic compound having replaceable nuclear hydrogen the product is brought into a liquid state by means of heat and/or the addition of a solvent such as a lower aliphatic or aromatic hydrocarbon or chlorinated hydrocarbon, and then separating it from the sulphuric acid.  Advantageously, the solvent is the aromatic reactant present in excess of the stoichiometric amount required for the condensation and the temperature during separation is maintained above the temperature of liquefaction of the product phase by dilution with a limited amount of water so that the strength of the sulphuric acid does not fall below 80 per cent.  Before separation of the product and acid phases by gravity, the liquid product phase may be scrubbed with the strong sulphuric acid.  The reactants are preferably emulsified in sulphuric acid of strength at least 95 per cent and not more than 98 per cent, as described in copending Specification 589,465, the acid being maintained at that strength throughout the reaction, e.g. by introducing sulphur trioxide or oleum as required.  The temperature of the reaction mixture being kept between 10 DEG  and 40 DEG  C.  When chloral and chlorobenzene are condensed, one mole. of chlorine and at least 2.2 moles. of chlorobenzene are advantageous proportions.  Specified chloral compounds are: chloral hydrate, chloral alcoholate and chloral acetal.  Specified aromatic compounds are benzene, methoxy-benzene, phenetole, phenol, toluene and naphthalene.  In examples, chloral and chlorbenzene are reacted in the presence of sulphuric acid, the mass being maintained in the liquid state in each case by the addition of excess of chlorobenzene.
