Abstract
Synthetic resins are formed by the direct action of acetylene on phenol or its homologues in the presence of a mercury catalyst and sulphuric acid or one of its acid salts, water being practically absent. Acetylene, preferably in excess, is passed into a mixture of the phenolic body with the sulphuric acid or p acid salt, to which mercurous or mercuric oxide or sulphate has been added; the temperature is preferably maintained at 50-120 DEG C.; increased pressure may be employed; a solvent for the phenol, for example glacial acetic acid, an alcohol, or acetone, may be present. Examples are given in which phenol and cresol are the starting materials, the resulting product being finally rendered infusible and insoluble by any suitable method, such as treatment under heat and pressure with hexamethylenetetramine. Specifications 163,679 and 180,353 are referred to.
