Abstract: Process for the preparation of 4-chlorobenzenesulphonyl chloride, according to which chlorobenzene is reacted with chlorosulphonic acid in a halogenated aliphatic hydrocarbon, in the presence of an alkali metal salt and/or an ammonium salt of an inorganic acid. After washing the resulting reaction mixture with water and separating the halogenated aliphatic hydrocarbon layer, the water is driven off by distilling with the halogenated aliphatic hydrocarbon to obtain 4-chlorobenzenesulphonyl chloride in the anhydrous form. The anhydrous product thus obtained may be converted to 4,4%-dichlorodiphenyl- sulphone by reacting with chlorobenzene in the presence of a catalytic quantity of ferric chloride.

Abstract: Disclosed is a color-developing composition for pressure-sensitive recording sheet material of the self-contained type comprising (A) 100 parts by weight of a copolymer obtained by reacting a p-alkylphenol having an alkyl moiety of from 1 to 12 carbon atoms and phenol with formaldehyde and (B) from 1 to 20 parts by weight of a hindered phenolic compound selected from phenols having an alkyl, alkylene or hydroxyl substituent radical in at least the 2- or 6-position, or both, of the benzene ring and derivatives thereof, the copolymer and the hindered phenolic compound being homogeneously dissolved in mutual solution. The hindered phenolic compound is either added to the starting materials for the preparation of the copolymer or, at the end of the copolymerization reaction, added to the resulting copolymer and dissolved homogeneously in mutual solution.
