Abstract: 864,103. Vinyl chloride polymer compositions. FERRO CORPORATION. Aug. 10, 1959 [May 27, 1959], No. 27248/59. Class 2(6). Asbestos-filled vinyl chloride polymer resin compositions are stabilized by intimately admixing therewith not more than 20 parts by weight of boric acid per 100 parts of resin. The polymer may be polyvinyl chloride; a copolymer of at least 50% wt. vinyl chloride with, for example vinyl acetate and/or alcohol or vinylidene chloride; and mixtures of a major proportion of such polymers with other polymers. The composition preferably contains also 0À1 to 0À5 parts by weight of a phenolic antioxidant e.g. di-t-butyl-p-cresol or -phenol; t-butyl-, p-tamyl-, p-diisobutyl-, p-nonyl-, or p-dodecylphenol; and dimethyl di-(p-hydroxy phenyl) methane and 0À1 to 2 parts by weight of a compatible zinc compound such as zinc chloride or a zinc salt of an organic acid e.g. zinc acetate, butyrate, hexoate, 2-ethyl hexoate, caprylate, noctoate, ricinoleate, stearate, oleate, naphthenate, benzoate, salicylate, hydroxy-stearate, or adipate as light-stabilizer. Other optional ingredients specified are plasticizers e.g. di-2-ethylhexyl phthalate or epoxidized soya bean oil; fillers, e.g. calcium carbonate; and pigments e.g. titanium dioxide or organic or inorganic colourants.

Patent GB-862383-A (GB)
Title: Process for preparing steroid compounds
IPC: C07J5/00
Filed: 1957-09-02
Abstract: 21-Dihydrogen phosphates of 20-keto-21-hydroxy-steroids are prepared by reacting the corresponding 21-halo-steroids wherein the 21-halo substituent is other than fluorine with a mixture of silver dihydrogen phosphate, separating water-soluble reaction products from water-insoluble reaction products, and recovering the resulting 20-keto-21-phosphates from the water-soluble products.  The phosphates may be derived from 3,20-diketo-21-hydroxypregnene compounds e.g. a 3,20-diketo-21-hydroxy-4-pregnene or a 3,20-diketo-21-hydroxy-1,4-pregnadiene, or compounds having the general formulae: <FORM:0862383/IV (b)/1> wherein R1 represents hydrogen, fluorine or chlorine, R2 represents hydrogen or a b -hydroxy or keto group, and R3 represents hydrogen or a hydroxyl group.  The silver di-hydrogen phosphate may be formed in situ by adding silver phosphate and phosphoric acid to the steroid. Alternatively, the silver phosphate and phosphoric acid may be mixed before being added to the steroid reactant.  It is preferable to use about 2 moles of phosphoric acid per mole of silver phosphate.  A mono- or di-alkali metal salt of the steroid phosphate may be recovered from the reaction mixture by diluting with water, removing any organic solvent by vacuum distillation, raising the pH of the aqueous solution to 4 to 11 by adding an alkali metal base such as an alkali metal hydroxide or carbonate to convert the steroid phosphate to an alkali metal salt and to precipitate any excess of silver as silver phosphate, and recovering the desired salt from the aqueous solution.  The alkali metal salt may then be converted into the corresponding free steroid phosphate by acidification with a mineral acid or with a cation-exchange resin. The free steroid phosphates prepared by any of the methods referred to above may be converted to the corresponding 21-(dimethyl phosphate) esters by reaction with diazomethane, or may be converted into salts by suitable neutralizing agents such as sodium hydroxide, methoxide or carbonate, or potassium, ammonium, calcium or barium hydroxide.  In the examples cortisone, hydrocortisone, prednisone, prednisolone, 9a -fluoro (and chloro)-hydrocortisone and corticosterone 21- dihydrogen phosphates, cortisone, hydrocortisone, prednisolone and 9a -fluorohydrocortisone 21-dimethyl phosphates, the disodium salt of hydrocortisone 21-dihydrogen phosphate and the monosodium salt of prednisolone 21-dihydrogen phosphate are prepared. Specifications 805,828 and 826,365 are referred to.

Title: Synthesis of diamines
IPC: C07C209/02
Filed: 1957-09-03
Abstract: Products corresponding to the addition of two unsubstituted or substituted amino radicals to a dimer of a conjugated diene are prepared by reacting said diene with free amino radicals or substituted free amino radicals, generated in a system known to be capable of producing such radicals, in an inert non-aqueous solvent for said diene.  The free amino radicals may be generated by treating an hydroxylamine <FORM:0821984/IV (a)/1> where R and R1 are hydrogen or aliphatic or aromatic radicals (e.g. N-benzylhydroxylamine, N-phenylhydroxylamine or hydroxylamine) or an oxime R11=NOH, where R11 is a substituted methylene group (e.g. acetone oxime), with a metal salt undergoing an oxidation-reduction reaction therewith (e.g. titanous, manganous, stannous and vanadous salts).  Specified dienes include isoprene, butadienes, pentadienes, cyclopentadiene and cyclohexadienes.  In one particular embodiment an alcohol solution of titanium tetrachloride, hydroxylamine and a conjugated diene is subjected to an elevated hydrogen pressure in the presence of a hydrogenation catalyst.  The products may also be reduced with hydrogen to form the corresponding saturated diamines. Specifications 802,185 and 804,312 are referred to.

Title: Improvements relating to the preparation of detergents and wetting agents
Filed: 1936-10-17
Abstract: Wetting-agents and detergents comprising salts of acid esters derived from oxygen containing mineral acids and alcohols or olefines having 8 to 25 carbon atoms in the molecule are purified by adding to the aqueous solution of the salt a water soluble volatile organic liquid capable of forming a constant boiling mixture with water, removing a substantial part of the organic liquid whereby part of the water is also removed, and the inorganic salts present precipitated, and recovering the alkyl ester salt after removal of the inorganic salts. In an example, the products obtained by limited oxidation of paraffin wax with air are saponified to separate the fatty acids and the unsaponified fraction, after extraction, hydrogenated to convert the aldehydes and ketones.  The resulting secondary and tertiary alcohols are sulphonated with chlorsulphonic acid in ether, neutralized and extracted with petroleum naphtha to remove unsulphated material.  The aqueous product is converted into a paste by evaporation, propyl alcohol is added and evaporation continued until the inorganic salts are precipitated.  In order to facilitate the separation of the latter, an anhydrous organic solvent, e.g. propylalcohol may be added.  The salts of esters derived from phosphoric acid and alcohols or olefines are referred to.  The olefines may be obtained by cracking paraffin wax or petrolatum.

Abstract: Witherite is cleaned by froth flotation, the frothing or conditioning or both being effected at a temperature in the range 25 DEG C.-55 DEG C. preferably 35 DEG C.-50 DEG C.  Impurities such as sulphides, carbonaceous compounds and siliceous gangue may be removed by a preliminary frothing using a sulphydric collector (e.g. a xanthate) and a frothing agent (e.g. pine oil and/or cresylic acid).  The main froth flotation uses a carboxylic collector (e.g. a resin acid, or a fatty acid of high molecular weight such as oleic or stearic acid) and/or a collector consisting of a higher alcohol sulphate, e.g. sodium laurylsulphate.  The pulp is to be kept alkaline.  Sodium silicate or quebracho extract may be added to aid gangue depression.
