Patent GB-369182-A (GB)
Title: Manufacture of artificial masses
IPC: C08G8/28
Filed: 1930-09-08
Abstract: Artificial masses are manufactured by causing a mixture of a synthetic resin carboxylic acid with a fatty acid or fatty acid ester of low volatility to reach with a polyvalent alcohol at a temperature not considerably above 100 DEG  C.  A solvent, e.g. an aromatic hydrocarbon such as toluene or a high-boiling alcohol such as butyl alcohol, may be added to produce a better homogeneity.  The product may be converted, by heating, preferably in a vacuum, to 150-200 DEG C., into a final product which is difficultly fusible or infusible, or difficultly soluble or insoluble.  In examples: (1) the resin carboxylic acid obtained by the action of formaldehyde solution on phenoxyacetic acid is mixed with ricinoleic acid, glycerine, and isobutyl alcohol and heated to 100-120 DEG  C.; the product can be used as a lacquer or may be further concentrated in a vacuum and heated to 150-180 DEG  C. to produce an infusible and insoluble, very elastic final product; (2) the resin carboxylic acid from formaldehyde and cresoxyacetic acid is heated in a vacuum to 130-140 DEG  C. with oleic acid and pentaerythrite, producing a viscous syrup which by heating for a longer time or at a higher temperature passes into an insoluble form; (3) a formaldehyde-cresol resin is treated with chloracetic acid and the resin carboxylic acid formed is dissolved in hot aqueous ammonia and the solution mixed with linoleic acid and glycol; the product may be used as an alcohol lacquer or for impregnating materials such as paper, sawdust or vegetable fibre for producing hardened artificial masses; (4) formaldehyde is condensed with cresoxyacetic acid (produced by the action of chloracetic acid on cresol) and the product is dissolved in a mixture of toluene and butanol, the solution mixed with wood oil, glycerine, and castor oil, and the mixture boiled, and finally heated in a vacuum to 130-160 DEG C.; the product is suitable for preparing lacquers; (5) the resin carboxylic acid obtained as in (3) is heated in a vacuum to 100 DEG C. with castor oil and glycerine; the product may be diluted with alcohol to produce a lacquer, or may be hardened, alone or in admixture with a filler such as cellulose, by heating to 150-180 DEG C.; (6) the resin carboxylic acid of (3) is mixed with wood oil and glycerine and heated to 100 DEG  C., yielding a syrup which may be mixed with substances such as sawdust, asbestos, kieselguhr or graphite and the mass converted to a final product by heating to 150 DEG  C. or above; (7) the resin obtained from formaldehyde and commercial "tricresol" is treated with chloracetic acid and the product is mixed with linoleic acid, butyl alcohol, and toluene and heated in a vacuum to 110-120 DEG  C., yielding a syrup which becomes insoluble on long heating.  Specification 298,085, [Class 2 (iii), Dyes &c.], is referred to.ALSO:Artificial masses are manufactured by causing a mixture of a synthetic resin carboxylic acid with a fatty acid or fatty acid ester of low volatility to react with a polyvalent alcohol at a temperature not considerably above 100 DEG  C., if desired in the presence of a solvent such as an aromatic hydrocarbon (e.g. toluene) or a high-boiling alcohol (e.g. butyl alcohol).  The products, alone or mixed with suitable materials, may be further heated to 150-200 DEG  C. to produce final products which are difficultly fusible or infusible or difficultly soluble or insoluble. In examples: (1) the product of the treatment of a phenol-formaldehyde resin with chloracetic acid is dissolved in hot aqueous ammonia and to the solution are added linoleic acid and glycerine; the product is used for impregnating materials such as paper, sawdust or vegetable fibre, the impregnated material then being heated; (2) the same resin carboxylic acid is heated in a vacuum to 100 DEG  C. with castor oil and glycerine and the product, mixed with a filling agent such as cellulose is hardened by heating to 150-180 DEG  C.; (3) the same resin carboxylic acid is mixed with wood oil and glycerine and heated to 100 DEG  C., yielding a syrup which may be mixed with substances such as sawdust, asbestos, kieselguhr or graphite and the mass converted to a final product by heating to 150 DEG  C. or above.  Specification 298,085, [Class 22, Cements &c.], is referred to.
