Title: Production of steroid compounds
IPC: C12P33/00
Filed: 1956-12-21
Abstract: 17-Hydroxy substituted steroids are produced by subjecting steroids having a hydrogen atom and no hydroxy group attached to the 17-position to the action of an oxygenating enzyme produced by growing an oxygenating strain of a micro-organism of the species Sporomia minima.  The oxygenation may be carried out by growing the micro-organism in a nutrient medium containing assimilable sources of carbon and nitrogen under aerobic conditions in intimate contact with the steroid, or by subjecting the steroid reactant under aerobic conditions to the action of homogenized resting cells obtained by growing the micro-organism under aerobic conditions in a nutrient medium.  The nutrient medium may contain assimilable sources of carbon and nitrogen, particularly dextrose, lactalbumin digest and corn steep liquor.  The steroid reactant may be a pregnene, pregnane, allopregnane, and may be unsubstituted or may contain substituents such as keto, hydroxy, acyloxy, halogen and alkyl substituents, e.g. androstanes, bile acids and their esters, sterols, sapogenins and derivatives of such compounds.  The 17-position in a reactant may contain a side chain such as a ketol side chain, a saturated or unsaturated hydrocarbon side chain or a carboxylic side chain. Specified reactants are progesterone, 4-pregnene-21-ol-3,20-dione-21-acetate, desoxycorticosterone, 4-pregnene-3,20-dione, 3-keto, cholanic acid, lithocholic acid, 4-pregnene-3-ol-20-one, 5-6-dichloropregnane-3-ol-20-one, and 5,-6-dichloropregnane-21-ol-3,20-dione.  In the examples 4-pregnene-17a -ol-3,20-dione, 4-pregnene-11 b , 17a , 21-triol-3, 20-dione, 4-pregnene-11m, 17a -diol-3,20-dione and 4-Oregnene-17a ,21-diol-3,20-dione are prepared.

Title: Improvements in the production of cellulose derivatives
IPC: D06M13/35
Filed: 1957-12-17
Abstract: A cellulose derivative which exhibits no afterglow when burned or charred contains an organic sulphonyl group and/or a halogen atom together with 0,2%-2% by weight of phosphorus in the form of dialkyl phosphonyl groups.  Cellulose derivatives having flame- and glowresistant properties are prepared by swelling the cellulose material either by wetting it with water or by mercerizing, esterifying with an organic sulphonyl chloride, and phosphorylating to produce a cellulose derivative containing 0,2%-2% by weight of phosphorus in the form of dialkyl phosphonyl groups, the phosphorylation being effected by adding a dialkyl halophosphate in a solution of a tertiary amine, e.g. pyridine, lutidine or quinoline, at a temperature below 100 DEG C. for a period of less than one hour. The flame resistance of the cellulose derivative may be increased by treating it with an aqueous solution of a halogen salt, e.g. sodium fluoride, chloride, bromide or iodide or the corresponding potassium or ammonium salts, having a pH of 5-9, to replace one or more of the sulphonic ester groups present by halogen.  Suitable organic sulphonyl chlorides are methyl, ethyl, isopropyl, phenyl and benzyl sulphonyl chlorides.  The phosphorylation is preferably carried out using diethyl chlorophosphate in amount corresponding to 3 moles of phosphorylating agent to 1 mole of cellulose (based on a molecular weight of 162 for the glucose anhydride unit). Esterification with the organic sulphonyl chloride and phosphorylation may be carried out successively or simultaneously. Halogenation is preferably effected subsequent to phosphorylation, although the cellulose may first be esterified and then halogenated before phosphorylation.  The esterification and halogenation may be effected simultaneously by using p-bromobenzene sulphonyl chloride, and all three steps of the process may be carried out simultaneously by using the latter type of reagent and the phosphorylating agent in a single reaction medium. The cellulose material may be in the form of a textile fabric, e.g. woven and belted cotton and rayon fabrics, cotton linters, paper or paper-making fibres, leaf and bast fibres, e.g. flax, hemp and sisal, cellulose films, viscose rayon, cuprammonium rayon, mattress filling materials or mixtures of fibres in which cotton or viscose rayon is blended with wool, silk or other fibres.  Specifications 694,217 and 873,555 are referred to.
