Abstract: 528,428. Artificial silk &c. FERRETTI, A. May 6, 1939, No. 13624. Convention date, May 7, 1938. [Class 2 (ii)] Artificial fibres are obtained from vegetable albumin substances by extruding an alkaline solution of the vegetable albumin into an acid co-agulating bath, which may contain soluble salts, and rendering the fibres insoluble by treatment in a bath containing both formaldehyde and one or more soluble salts, preferably sodium chloride and an aluminium salt. The albumin used may be vegetable casein obtained from soya beans. It may be used in admixture with milk-casein. The fibres may be passed from the co-agulating bath, in the form of a continuous ribbon under tension, into a solution of sodium chloride with or without an aluminium salt or formaldehyde. They may be cut to the desired length and then immersed in an aqueous formaldehyde bath containing formaldehyde and sodium chloride with or without an aluminium salt. They may then be rendered insoluble by treatment in an aqueous bath containing formaldehyde and one or more soluble salts at a temperature above 25‹C. A mixture of soya-casein and whey casein is mixed with water, and then with a solution of caustic soda and sodium hyposulphite. Caustic potash may be used instead of caustic soda. The solution is filtered, and matured. It is then extruded into a co-agulating bath containing an aqueous solution of sulphuric acid and a salt such as sodium sulphate, sodium chloride, aluminium sulphate, zinc sulphate, or ammonium. sulphate. The bath has a density greater than 1.18 and a sulphuric acid content greater than 25 grams per litre. The bath is heated. The co-agulated filaments are collected as a ribbon and passed through a sodium chloride bath to which aluminium salts or formaldehyde may be added. Preferably this bath is heated. The ribbon is passed through a second bath containing aluminium salts and sodium chloride with or without formaldehyde, The fibres are cut to staple length and then immersed in a solution of aluminium salts and sodium chloride with or without formaldehyde. They are then rendered insoluble by treatment in a bath containing formaldehyde, aluminium salts and/or sodium chloride at a temperature above 25‹C., preferably above 70‹C. or they may be treated in a similar bath at a lower temperature and then in an aqueous bath of formaldehyde at a temperature exceeding 25‹C. The fibres may finally be treated with aqueous solutions of mono-, di- or tri-sodium phosphate.

Patent GB-456663-A (GB)
Title: Manufacture of compounds containing the aetiocholane nucleus
IPC: C07J75/00
Filed: 1935-05-09
Abstract: Unsaturated compounds containing the äetiocholane nucleus are isolated from their halogen addition compounds by treating the halogen addition products with catalytically activated hydrogen at ordinary temperature; if desired in the presence of acid binding agents.  Under these mild conditions, the reaction ceases after the removal of the halogen and without saturation of the double links. As catalysts, the noble metals are preferred, such as platinum or palladium.  Ordinary metals such as nickel or cobalt may also be used, but in this case it is particularly desirable that an acid binding agent should be present such as an alkali hydroxide, an alkaline earth hydroxide, magnesia, or an organic base.  Mixtures of the above catalysts may be used with or without a carrier. Halogenated bodies mentioned which may be converted into the corresponding unsaturated compounds are stigmasterol acetate tetrabromide, cholestenone dibromide, dehydroandrosterone dibromide, pregnendione dibromide, together with halogen addition products of bile acids or sapogenine.  In examples: (1) a glacial acetic acid - ether solution of cholesterol dibromide is treated with a palladium barium sulphate catalyst and shaken with hydrogen at 20--25 DEG  C. At the end of the reaction the catalyst is removed by filtration, the ether evaporated and the cholesterol precipitated by the addition of water.  In a similar manner, platinum black may be used as the catalyst; (2) cholesterol acetate dibromide and a nickel catalyst are suspended in absolute alcohol, made alkaline with caustic soda and shaken with hydrogen. The alkaline solution is freed from catalyst and boiled to saponify the ester.  On cooling cholesterol crystallizes; (3) an alcoholic suspension of stigmasterol acetate tetrabromide and a nickel catalyst are treated as in example (2) to yield pure stigmasterol; (4) an alcoholic suspension of sitosterol acetate dibromide and a nickel catalyst are treated as in example (2) to yield pure sitosterol; (5) an acetic acid solution of the neutral body obtained by the chromic acid oxidation of cholesterol acetate dibromide is mixed with an alkaline alcoholic suspension of a nickel catalyst and shaken with hydrogen.  To the catalyst free residue semicarbazide acetate is added.  The resulting semicarbazone is decomposed by saponification with strong alcoholic sulphuric acid, to yield dehydroandrosterol in two polymorphous forms.
