Abstract
Water soluble or dispersible condensation products are prepared by condensing in presence of alkali (1) one mol. of a mixture of a phenol and a sulphonated phenol in the molecular ratio of at least 2 : 1 and (2) at least one mol of formaldehyde. Specified unsulphonated phenols are phenol, the cresols, the xylenols and the naphthols. Specified sulphonated phenols are the sulphonic acids of phenol, the cresols, the xylenols and the naphthols, and sulphonated novolaks. Specified alkalis are caustic soda and potash, ammonia, alkaline earth oxides and organic bases. Aqueous solutions of the condensation products are acid-hardening and may be employed as glues, tannins, binding materials, textile auxiliaries, dispersing agents and protective colloids. In examples (1) Phenol is partially sulphonated, caustic soda and formalin added and the mixture heated, phenol added and the mixture further heated. (2) Cresol is partially sulphonated, caustic soda and formalin added, the mixture heated, phenol added and the mixture further heated. (3) A cresol mixture is partially sulphonated, caustic soda and formalin added, the mixture heated, cresol added, and the mixture further heated. (4) A naphthol mixture is partially sulphonated, caustic soda and formalin added, the mixture heated, cresol added and the mixture further heated. The products of the examples may be worked up into dry resins. Specifications 703,233 and 703,235 are referred to.
