Patent GB-377265-A (GB)
Title: Improved method for the manufacture of plastic materials
IPC: C08G63/46
Filed: 1931-04-17
Abstract: Plastic material is prepared by the condensation of polyhydric alcohols, e.g. glycerine, glycol, polyglycerine, polyglycol, pentaerythrite, with the product obtained on oxidizing oils containing the glycerides of unsaturated acids.  The process of oxidation may also cause saponification of the oil, in which case the glycerine set free may be removed or may be utilized as part of the polyhydric alcohol required for the condensation, but it is preferred to oxidize in such a way that the ester linkage is not destroyed, so that the dicarboxylic acids produced are already partly esterified. In either case, monocarboxylic acids may be removed from the oxidation product before the final condensation. Other mono- or polybasic acids and also other artificial and natural resins may be added prior to or during the condensation. In examples, (1) olive oil, dissolved in acetone or emulsified in potash solution, is oxidized with permanganate and the saponification completed by boiling.  The manganese compound is filtered off, and the filtrate extracted with ether, or neutralized and extracted with alcohol.  The solvent is removed, glycerine added to the residue, and the whole heated to 170 DEG  C. to yield a resin.  (2) Olive oil in acetone is oxidized with permanganate, and the whole treated with dilute sulphuric acid in the cold, whereby saponification is avoided.  The monocarboxylic acids are removed by distillation in vacuo and the residue condensed as before.  By using much less permanganate, some of the oleic acid is not oxidized, and very soft products are obtained. (3) Nitric acid is the oxidizing agent.  (4) Linseed oil in chloroform is oxidized by means of ozone.  In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the oils may first be saponified and then oxidized.  This subject-matter does not appear in the Specification as accepted.

Patent GB-142480-A (GB)
Title: Improved manufacture of sugar and furfurol from wood and other cellulose-containing substances
IPC: C13K1/02
Filed: 1920-04-27
Abstract: In the manufacture of furfurol, methyl alcohol, and easily fermentable glucose from materials containing cellulose, a larger yield is obtained by the addition of a small quantity of an acid or acids besides the acid required for the conversion purpose. Hydrochloric, sulphuric, sulphurous, and hydrofluoric acids are suitable, or acid salts, or salts decomposed by excess of acid or hydrolytically, e.g. chlorides of magnesium, calcium, aluminium, zinc, and manganese.  When several additional acids are used, excess of one ingredient is preferable.  When hydrochloric acid is employed as the conversion agent, a mixture of sulphuric and sulphurous acids is preferred as catalyst.  The ligneous material is mixed with one half to less than an equal volume of water in order to prevent formation of non-fermentable sugars.  After the vapours from a preliminary steam-treatment in an autoclave have been removed, the requisite acids are introduced, the conversion acid being added in sufficient quantity to leave the treated material so that it can readily be disintegrated, and the pressure is raised to 7 or 8 atmospheres.  Steam may be employed at lower pressure by the addition of special "protective" substances, e.g. metallic oxides.  On completion of the conversion process, the contents are rapidly cooled by evacuation into a cooling-chamber, where the furfurol is condensed.  Any furfurol or methyl alcohol remaining in the residues is removed by suction or by blowing in steam.  The sugar solution is obtained from the residue by lixiviation.
