PURPOSE:The reaction of a disulfonate of an alkylene diol or a dihaloalkane with a thiophenol bearing a hydroxyl group readily and inexpensively gives a compound which is used as a recording material, especially as an additive for thermosensitive recording materials. CONSTITUTION:The reaction of a disulfonate of an alkylene diol or a dihaloalkane with a thiophenol bearing an aromatic hydroxyl group is carried out in a solvent such as acetonitrile in the presence of a base such as sodium hydroxide at 50-100 deg.C to etherify the remaining aromatic hydroxyl whereby the objective compound is obtained. It is preferred to use, in this process, 1mol of the dihaloalkane or diol disulfonate, 2-4mol of the thiophenol and 2-6mol of the base. |
