| titleOfInvention | Improvements in and relating to reaction products of aldehydes and diazine derivatives |
| abstract | Resins are made by condensing an aldehyde with a 2.4.6-tri-alkylamino-pyrimidine in which the alkyl group is methyl, ethyl, propyl, or isopropyl, and which may have a methyl group in the 5-position. Inorganic and organic bases and acids are specified as catalysts, and lists of modifying ingredients are given comprising ureas, amides, aminotriazines, phenols, alcohols, and amines. The resins may be used in paints, as casting resins, and in moulding compositions. In examples, 2.4.6-tri-methylamino-pyrimidine is reacted with formaldehyde, in presence of ammonia or caustic soda or both, and in presence of further substances as indicated, i.e. (1) chloracetamide, or citric acid, phthalic anhydride malonic acid, oxalic acid, sodium chloracetate, N-diethyl chloracetamide, glycine ethyl ester hydrochloride, di-and trichloracetamides, chloroacetonitriles, a - or b -dibromopropionitrile, aminoacetamide hydrochloride, ethylene diamine and ethanolamine hydrochlorides, nitrourea, chloracetylurea, glycerine, sulfamic acid, citric diamide; (2) urea and chloracetamide; (3) p-ureidobenzene sulphonamide; (4) butyl alcohol; (5) acetamide; (6) diethyl malonate; (7) glycerine; (9) polyvinyl alcohol; the products of (1) and (2) being made into a moulding powder with alpha-cellulose and zinc stearate, and the products of the other examples being cured on a hot plate with glycine or chloracetamide. In example 8, 2.4.6-trimethylamino-pyrimidine is reacted with acrolein in presence of sodium hydroxide and the product cured with glycine, chloracetamide, or sulphamic acid. Other aldehydic compounds specified are paraformaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, heptaldehyde, octaldehyde, methacrolein, crotonaldehyde, benzaldehyde, furfural. 2.4.6-Trialkylaminopyrimidines are made from the corresponding tri-chloro or tri-bromo derivative and a primary amine, or from the triamino pyrimidine and an inorganic acid mono salt, e.g. monohydrochloride, of a primary amine. The Specification as open to inspection under Sect. 91 lists a large number of tri(-alkyl-, aryl, -aralkyl, and -alkaryl)-amino-pyrimidines, including unsaturated bodies. This subject-matter does not appear in the Specification as accepted. |
