Title: Improvements in and relating to heat-coagulable foaming agents
IPC: A23C21/00
Filed: 1942-06-17
Abstract: A heat-coagulable foaming agent, particularly for use in flour or sugar confectionery, is produced by diluting with water whey paste, after its lactose content has been reduced, rendering the mixture alkaline, adding a flocculating agent, acidifying the medium and removing undissolved matter.  The flocculating agent may be a soluble polysaccharide, e.g. starch or tragacanth, or a soluble salt of an acid, e.g. pectic or alginic acid, derived from a polysaccharide. One half of the whey paste diluted with 10-12 times its weight of cold water may be rendered just alkaline, pH 7.4-7.6, treated with a soluble alginate and acidified by addition of the untreated diluted whey paste.  The liquor is then clarified and concentrated in a vacuum vessel below 140 DEG  F. until it contains 75-85 per cent soluble solids.  The solid residue may be hydrolysed to produce amino acids &c.

Title: Manufacture of organic bismuth compounds
IPC: C07F9/94
Filed: 1932-03-21
Abstract: The bismuth salts of the unsaturated acid C9H14O2 (obtained as below) and of the saturated acid C9H16O2 derived from the unsaturated acid by reduction are obtained by producing a neutral solution of the acid in water by means of alkali carbonate, adding to the solution a solution of a bismuth salt such as the nitrate or chloride preferably containing glycerin, and separating the precipitated bismuth salt. During the reaction, a solution of an organic acid salt, particularly of sodium acetate, may be added.  The precipitated salt may be purified by washing with water and extracting with chloroform and is soluble in ether, chloroform, and oils.  The unsaturated acid C9H14O2 is obtained as a by-product in the oxidation by chromic acid of commerically pure terpene alcohols.  For instance, in the manufacture of camphor from turpentine oil, the camphene, borneol, or isoborneol obtained as intermediates are oxidized by chromic acid and sulphuric acid in benzene solution.  The benzene layer is separated and washed with caustic soda, and the alkali extract separated and acidified with hydrochloric acid, whereby an oil containing the unsaturated acid is deposited.  The crude oil may be used in the production of the bismuth salt, or the pure acid be first obtained by fractional distillation under reduced pressure.  The saturated acid C9H16O2 is obtained by catalytic hydrogenation of the acid C9H14O2 or the crude oil containing it.ALSO:The unsaturated acid C9H14O2 is obtained as a bye-product in the oxidation by chromic acid of commercially pure terpene alcohols.
