Title: Improved method for the extraction of tea aroma
IPC: A23F3/42
Filed: 1929-07-01
Abstract: 335,901. Strobach, O., and Wickmann, P. A. July 1, 1929. Tea preparations.-An extract of tea is prepared by treating the leaves with an organic solvent (e.g. petroleum ether, pentane, chloroform, ether and the like) and removing the solvent to leave a dark green paste, the chlorophyll, fat and wax-like constituents being thereafter removed from the paste by treatment first with 70-80 per cent alcohol and then with a solvent such as petroleum ether, the tea-aroma residue after distilling off the last-named solvent remaining as a yellowish green or a golden green paste. The tea leaves may be extracted with the suitable organic solvent in a Soxleth extraction apparatus, the solvent being thereafter removed from the extract. As solvents for treating the tea leaves fat, oil and wax may also be used by allowing the leaves to stand for a. long time in contact with these substances. The fat-extract is then shaken with 70-80 per cent alcohol and filtered off, the alcohol being thus removed and the residue treated with. a, solvent such as petroleum ether, as described above. Preferably the tea paste is diluted by the addition of sugars to deposit the tea aroma on the pulverulant additions. It is prefered also to add caffeine and tannic acid extracts, prepared from the tea leaves remaining in the extraction apparatus. Tablets are prepared by dissolving the paste in petroleum ether, adding tannic acid extract and caffeine, and stirring the mixture. The product may be mixed with sweets, chewing gum, milk, and other edible substances.

Title: A method for the preparation of nuclear substituted quinoline compounds and intermediates therefor
Filed: 1946-07-05
Abstract: Compounds of the general formula Ar-N=CH-CH(CN)-COOR or ArNH-CH=C(CN)-COOR, wherein Ar represents a phenyl group which may or may not contain one or more substituents and R represents an alkyl group, one prepared by heating a reaction mixture comprising substantially equimolecular proportions of an aniline having a hydrogen atom in at least one of the ortho positions in the molecule, an alkyl orthoformate, and a cyanacetic ester of the general formula CN-CH2-COOR, where R has the above significance, the mixture being heated to a temperature between 130 DEG  and 170 DEG  C. for a time sufficient to effect the splitting out of substantially 3 molar equivalents of an aliphatic alcohol.  The substituents may be halogen atoms or alkyl, haloalkyl or alkoxy groups.  In an example, ethyl-a -cyano-b -(m-chloranilino)-acrylate is prepared by heating ethyl cyano-acetate, ethyl orthoformate and m-chloraniline.  Substituted quinolines are prepared by cyclizing compounds of the above general formula by heating in at least 10 parts by weight or at least 30 parts by weight of an inert solvent having a boiling point of at least 200 DEG  C., e.g. mineral oil or diphenyl ether, to split out a fourth molar equivalent of an alcohol.  The resulting 3-cyano-4-hydroxy quinoline may be hydrolysed to the corresponding acid, e.g. by treatment with sulphuric acid of at least 60 per cent strength, and the free acid may then be decarboxylated by fusion or by heating in a high boiling solvent to form a 4-hydroxy-puinoline. In an example, 7-chloro-3-cyano-4-hydroxyquinoline is prepared by heating ethyl-a -cyano-b -(m-chloranilino)-acrylate dissolved in diphenyl ether, and is hydrolysed to 7-chloro-3-carboxy-4-hydroxyquinoline which may then be decarboxylated by fusion to yield 7-chloro-4-hydroxyquinoline. Specification 627,297 is referred to.  The Specification as open to inspection under Sect. 91 refers to the above process wherein the group Ar may represent an aryl radical.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the insolubilisation of cellulose ethers
IPC: C08B15/10
Filed: 1954-07-19
Abstract: A free acid cellulose glycollic or hydroxypropionic acid ether which is soluble in aqueous ammonia is rendered insoluble in water, dilute aqueous acids and dilute aqueous caustic alkalies at room temperature by treating the ether in aqueous solution with sufficient available formaldehyde or glyoxal in the presence of ammonia for a sufficient time to cross-link the ether.  The formaldehyde or glyoxal and/or the ammonia may be present in the free form or in the form of reagents capable of yielding the free compounds under the conditions of the reaction.  The molar ratio of available ammonia to the glycollic or hydroxy-propionic acid residues of the cellulose ether may be from 0.5 : 1 to 3.0 : 1, and the molar ratio of the available aldehyde to these residues may be at least 1 : 1 and preferably at least 8 : 1. The pH of the solution may be 2-10, preferably 5-8.  The degree of substitution of the cellulose ether may be 0.5 to 2.0.  The cellulose ether solution should have a specified minimum viscosity, as determined by a method described in the Specification.  Instead of ammonia there may be used ethylene diamine, ethyl amine or propyl amine.  As aldehyde-yielding materials there may be used hexamethylene tetramine, paraformaldehyde, trioxane, or tetraoxymethylene.  In an example, 3 grams of free acid cellulose glycollic acid ether of D.S. 1.23 which has been prepared by treating the sodium salt with a solution of hydrochloric acid in aqueous ethanol and washing the product with aqueous ethanol, is mixed with 20 cc. of 29 per cent aqueous ammonium hydroxide and the solution made up to 100 c.c. with water.  The solution is boiled until its pH is reduced to 7 and 25 c.c. of 37 per cent formaldehyde solution are added.  The gel or viscous solution prepared by the described treatment of the cellulose ether may be used for the production of films and fibres or for impregnating fabrics, fibres, yarns or paper.
