Abstract
Synthetic resins are produced by subjecting an aldehyde or its products of condensation or polymerization to the continued action of a mineral acid or acid salt, in the presence of a solvent if desired and preferably at a raised temperature. The products may then be hardened by prolonged heating at a high temperature, with or without the separation of the excess of acid. Further hardening may be effected by fusion with metal oxide or esterification with an alcohol, such as glycerin, before or after the heat treatment. The synthetic resins, when dissolved in the usual resin solvents, can be used as lacquers, polishes and finishes; and, being of low melting point, they can be added to other resins to render them more fusible. According to the examples, (1) acetaldehyde and sulphuric acid are heated together at 40 DEG C. for some hours and then raised to 100 DEG C. until a sample sets on cooling to a tough mass; the product is maintained in the molten condition, about 150 DEG C., for a long time, and sets when cold to a hard resin; (2) crotonic aldehyde is heated with hydrochloric acid, or with sulphuric acid in the presence of acetic acid as a solvent, or acetaldehyde is heated with sodium bisulphate solution, and the products in each case are further treated as in example (1). Specifications 16848/13, 17017/13 and 132557 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the oxidation of the resins to bleach them and to render them soluble in borax. This subject-matter does not appear in the Specification as accepted.
