Title: Process of evaporating sea water or other liquids from which water or other liquid is to be removed
IPC: C02F1/02
Filed: 1931-11-26
Abstract: In evaporating liquids which tend to form deposits on the heating surfaces, such deposition is prevented by keeping the liquid in the heater under such pressure that no vapour bubbles are formed at the surfaces of the liquid in direct contact with the heating surfaces. Thus in the case of sea water boiling at 100 DEG  C. under atmospheric pressure, at 104 DEG  C. under a pressure of 1,2 atmospheres, and at 120 DEG  C. under a pressure of 2,0 atmospheres, if the maximum temperature of the heating surfaces is 120 DEG  C., the pressure on the liquid is increased to at least 2,0 atmospheres.

Filed: 1935-11-30
Abstract: Polyoxy-carboxylic acids or their salts are obtained by oxidation of trihexosan in alkaline solution with, for example, a permanganate, halogen, hypohalite, or hydrogen peroxide.  Mono-or di-carboxylic acids are obtained depending on the amount of oxidizing agent used. They may be precipitated as basic barium salts from which the free acids or other salts, e.g. the soluble neutral alkaline earth, iron, copper, manganese, nickel, and silver salts, can be prepared.  The compounds have a therapeutic use.  Examples describe the oxidation of trihexosan in aqueous caustic soda with potassium permanganate, bromine or bleaching powder, and hydrogen peroxide.  The solutions may be acidified to form the free acids which are precipitated with alcohol, or baryta added to precipitate a basic barium salt which is neutralized with acid, and the neutral barium salt, or the iron or copper salt obtained by double decomposition with ferrous or copper sulphate precipitated with alcohol.  Alternatively, the precipitate is treated with sulphuric acid to convert all the barium to sulphate. The acids are then precipitated with alcohol or neutralized with lime or magnesia, and the calcium or magnesium salts precipitated.ALSO:Salts of polyoxy-carboxylic acids are obtained by oxidation of trihexosan in alkaline solution with, for example, a permanganate, halogen, hypohalite, or hydrogen peroxide.

Title: The manufacture of aldehydes from ketones related to ª‰-ionone
IPC: C07C47/38
Filed: 1947-12-18
Abstract: The process of the parent Specification is applied to 2-(methylcyclohexenyl)-vinyl alkyl ketones (other than b -ionone) and 2-(methylcyclohexadienyl)-vinyl alkyl ketones and compounds derived from these by opening the ring at the 11-position, these ketones being condensed with a halogeno-acetic ester and the product treated with an alkali to produce a 4-substituted-2-alkyl-butene-(2)-al-(1), the whole process being carried out without the application of external heat; the alkyl group in the ketone starting material has 4 or less carbon atoms. Suitable starting materials are pseudo-ionone, a -ionone, dehydro - b  - ionone, b  - methylionone of the formula <FORM:0639888/IV (b)/1> and cyclic homologues of b -ionone of the formula <FORM:0639888/IV (b)/2> where R is hydrogen or methyl, one at least being hydrogen. Chloracetic esters are preferably used, and the temperature is not allowed to rise above 50 DEG  C. at any time.  The aldehydes obtained are extracted from the reaction mixture with a substantially water-immiscible liquid and may be characterised as the phenyl-semicarbazone or the thio-semicarbazone.  Examples show the treatment of pseudo-ionone and of a -ionone, the phenyl-semicarbazone of the product from the former being described.  Dehydro-b -ionone is obtained from 2 : 6 : 6-trimethylcyclohexadiene - (1 : 3) - al - (1) and acetone, or by the dehydrogenation of b -ionone.  b -Methyl-ionone of the formula given above is produced by the ring-closure of pseudomethylionone with sulphuric acid, the latter ketone being obtained by condensing citral with methyl ethyl ketone. The cyclic homologues of b -ionone are prepared by reacting acetylene with cyclohexanone or a methylcyclohexanone, dehydrating, forming the Grignard reagent, treating this with acetic anhydride and partially dehydrogenating.
