Abstract

1,155,431. Sulphur containing phenol condensates. SOCIETE NATIONALE DES PETROLES D'AQUITAINE. 12 May, 1966 [12 May, 1965; 9 May, 1966 (2)], No. 21165/66. Heading C2C. [Also in Division C3] Sulphur-containing phenoplasts are obtained by condensing a phenol containing at least one nuclear hydrogen atom and a dithiolthioether of the formula HS(CH 2 S) n H, n being 2-7, in the presence of an acidic halide catalyst with the liberation of H 2 S, with the proviso that the catalyst is not boron fluoride alone. The catalyst may be used in solution in an organic acid, and, further, a strong acid may be present. The condensation product may thereafter be heated with a compound which generates active methylene groups. Reference has been directed by the Comptroller to Specification 1,081,742.
