Disclosed is a single phase mixture of about 1 to about 99 wt % of a compound having the general formula ##STR1## where "n" is 1 or 2 and about 0. 1 to about 99 wt % of a liquid which can be a perfluoro aliphatic alkane from C. sub. 5 to C. sub. 8, a perfluoro cycloaliphatic alkane from C. sub. 5 to C. sub. 8, a perfluoro alkylcycloalkane having 5 to 8 carbon atoms in the ring and 1 or 2 branches of 1 to 3 carbon atoms each, a perfluoro-N-alkylmorpholine from C. sub. 5 to C. sub. 8, a perfluoro cycloether from C. sub. 4 to C. sub. 7, or a perfluoro polyether having an average molecular weight from about 400 to about 500.

Disclosed is a method of chlorinating the side chains of an aromatic compound having the general formula ##STR1## where each R is independently selected from R' or OR', each R' is independently selected from alkyl from C. sub. 1 to C. sub. 6, and n is an integer from 1 to 3. Some of the aromatic compound is incompletely. alpha. -chlorinated using about 0. 1 to about 0. 6 equivalents of chlorine per equivalent of the aromatic compound. The. alpha. -chlorinated aromatic compound is separated from unreacted aromatic compound and the. alpha. -chlorinated aromatic compound is further chlorinated. The two step chlorination of the aromatic compound reduces ring chlorination.

Disclosed is a method of separating the meta isomer of a halotoluene having the general formula ##STR1## from a mixture with at least one other isomer, where X is Cl or Br. About 0. 0001 to about 5 wt % of a Friedel-Crafts catalyst is added to the mixture and the mixture is exposed to a brominating agent which preferentially brominates the meta isomer. The mixture is then heated at a temperature above the boiling point of the other isomers but below the boiling point of the brominated meta isomer.

Disclosed is a method of making high purity 2,4- and 3,4-dichlorotoluene from parachlorotoluene that contains some metachlorotoluene. About 0. 0001 to about 5 wt % of a Friedel-Crafts catalyst and about 0. 5 to about 10 equivalents of a brominating agent are added to the parachlorotoluene. The metachlorotoluene is brominated, but most of the parachlorotoluene is not brominated. Without separating the brominated products from the unbrominated products, about 0. 5 to about 1. 5 equivalents of a chlorinating agent are added, whereby only the unbrominated products (i. e. , the parachlorotoluene) are chlorinated. The resulting 2,4-dichlorotoluene and 3,4-dichlorotoluene can be separated by distillation.

Disclosed is a method of separating the meta isomer of a haloalkylbenzene having the general formula ##STR1## from a mixture with at least one other isomer, where X is Cl or Br and R is alkyl from C. sub. 2 to C. sub. 12 or cycloalkyl from C. sub. 3 to C. sub. 8. About 0. 0001 to about 5 wt % of a Friedel-Crafts catalyst is added to the mixture and the mixture is exposed to a brominating agent which preferentially brominates the meta isomer. The mixture is then heated at a temperature above the boiling point of the other isomers but below the boiling point of the brominated meta isomer.

Disclosed is a single phase liquid composition comprising 0. 5 to 30 wt % of a benzotrifluoride solvent, about 0. 5 to about 50 wt % of a glycol ether cosolvent, up to about 50 wt % of an alkanol, up to about 10 wt % of a surfactant, and the remainder water. The composition is effective in cleaning hard surfaces, stripping paint, and as a carrier.
