Title: Polyurethane structure
IPC: B29C65/00
Filed: 1962-08-21
Abstract: A sprayable polyurethane liquid reaction mixture for use in spray moulding hollow objects, e.g. liquid containers (see Division B5) comprises a mixture of (1) a prepolymer of an organic polyisocyanate and a reactive hydrogen containing polymeric material e.g. polyesters, polyesteramides and polyethers, dissolved in sufficient nonreactive solvent to yield a sprayable mixture and (2) sufficient cross linking agent to react with the free polyisocyanate. It is desirable to add to the polyurethane mixture certain pigments i.e. carbon black and additives e.g. surface active agents and levelling agents such as cellulose acetate butyrate.  In the preferred embodiment the prepolymer used was prepared by reacting 2 mols. of toluene diisocyanate with 1 mol. of polyester prepared by the condensation of adipic acid with an excess of a mixture consisting of 80% by weight of ethylene glycol and 20% by weight of propylene glycol.  This prepolymer was used to prepare a black master batch by ball milling 1250 parts of this prepolymer with 375 parts cellosalve acetate, 125 parts carbon black and 375 parts of methyl ethyl ketone. Component 1 of the spray mixture was formed by mixing 165 parts of this master batch with a mixture of 1500 parts of the prepolymer, 450 parts cellosolve acetate, 450 parts methyl ethyl ketone and 72 parts of a solution of cellulose acetate butyrate containing 10% by weight of a mixture containing 50% xylene and 50% methyl cellosolve acetate. Component 2 of this sprayable mixture comprise 153 parts of methylene-bis-orthochloroaniline and 153 parts of methyl ethyl ketone.  Two other specific examples are given within the Specification.  Metal fittings are attached to the polyurethane by suitable adhesives such as one comprising 20 parts of 70/30 copolymer of styrene/acrylonitrile dissolved in 80 parts ethylene dichloride and 20 parts of a commercial epoxy resin such as Epon 828 dissolved in 80 parts of ethylene dichloride.

Title: Pgf-prostaglandins
IPC: C07C67/00
Filed: 1975-08-07
Abstract: The process allows a virtually quantitative conversion of the configuration of prostaglandines F alpha  into F beta . To this end, the 9 alpha -hydroxyl group is esterified selectively with a carboxylic acid in the presence of a hydrogen acceptor, for example quinones or azodicarboxylic esters, and of a catalyst M<V>Y3 in which M<V> denotes a non-metal of group V and Y denotes an alkyl, dialkylamino or aryl group, for example triphenylphosphine, triphenylarsine or triphenylstibine, and the resulting 9 beta -acyloxy radical and other acyloxy radicals which may be present are hydrolytically cleaved. To ensure specific esterification, ether groups which are present can be cleaved before or after hydrolysis while setting free the hydroxyl groups. The hydrolysis process can be carried out in such a manner that not only the acyloxy radicals but also a terminal carboxylate group are cleaved simultaneously or in succession.
