| abstract | Synthetic tanning-agents are prepared by heating sulphochlorides of oxyaryl-carboxylic acids with oxyaryl compounds in the absence of alkali, when condensation takes place with elimination of hydrochloric acid and products are obtained which are easily soluble in water. According to the examples, (1) salicylic acid sulphochloride is heated with phenol, hydroquinone, salicylic acid or 2-oxynaphthalene-3-carboxylic acid, (2) metacresotinic acid sulphochloride or 2-oxynaphthalene-3-carboxylic acid sulphochloride is heated with salicylic acid, (3) salicylic acid sulphochloride is heated alone to a temperature of 170-180 DEG C. |
