CFOCF.sub.2 (CF(CF.sub.3)OCF.sub.2).sub.n-1 (Rf).sub.m CO.sub.2 Rwherein n represents an integer of 1 to 5; m represents 0 or 1; Rf represents a C.sub.1 -C.sub.10 bifunctional perfluoro group and R represents an alkyl group, is produced by reacting fluorinated acyl fluoride having an ester group which has the formulaFOC(CF(CF.sub.3)OCF.sub.2).sub.n (Rf).sub.m CO.sub.2 Rwith an alkali metal carbonate to produce an alkali metal salt of fluorinated carboxylic acid having an ester group which has the formulaMOOC(CF(CF.sub.3)OCF.sub.2).sub.n (Rf).sub.m CO.sub.2 Rwherein M represnts an alkali metal;And then, thermally decomposing the alkali metal salt of fluorinated carboxylic acid having an ester group.

Abstract: Pharmaceutically active compounds of the formula ##STR1## wherein --OR.sub.1, --OR.sub.2, --OR.sub.3 and --OR.sub.4, which may be the same or different, each represents a free or esterified hydroxyl group and --COOR.sub.5 represents a free or esterified carboxyl group, are provided together with processes for their production and pharmaceutical compositions containing them. Compounds of formula II and III possess valuable cicatrizing and anti-inflammatory properties.

Abstract: The present invention relates in part to novel amido, cycloamido, carbonylamido and sulfonylamido derivatives and p-substituted phenyl esters of 9-deoxy-9-methylene-PGF-type compounds. These novel amides produce surprisingly prolonged oral activity as pharmacological agents, as compared to the previously known 9-deoxy-9-methylene-PGF-type compounds.Further, the novel p-substituted phenyl esters provide more stable pharmaceutical formulations as compared to known 9-deoxy-9-methylene-PGF-type esters.Additionally, a novel series of 16-phenyl-9-deoxy-9-methylene-PGF-type compounds in free acid, ester, C-1 alcohol, and C-1 amine form is provided. Such compounds exhibit characteristic prostaglandin-type pharmacological actions.

Abstract: New bromine compounds are provided. They correspond to the formulaH -- X' -- COO -- (X--OOC).sub.t-1 -- X" -- Hin which t is 1 or 2 and X, X' and X" are brominated alkylene. The new compounds are useful as flameproofing agents for synthetic fibers.

Abstract: A method for producing a 3,3-dimethyl-4-(2,2-dihalogenovinyl)-4-hydroxybutyric-1,4-lactone of the formula, ##STR1## wherein X is a halogen atom, which comprises reacting a 1,1,1-trihalogeno-4-methyl-3-pentene-2-ol of the formula, ##STR2## wherein X is a halogen atom, or a 1,1,1-trihalogeno-4-methyl-4-pentene-2-ol of the formula, ##STR3## wherein X is a halogen atom, or the mixture of the both compounds with vinylidene chloride of the formula, ##STR4## IN SULFURIC ACID.

Abstract: Immobilized enzymes, intermediates therefor, and a process for the preparation of such substances are described. The method comprises reacting an enzyme with a polymerizable, ethylenically, unsaturated monomer containing a reactive group, and then polymerizing or copolymerizing the covalently-bonded enzyme-monomer product thus produced in the presence of a cross-linking agent and an initiator. The process affords immobilized enzymes of high stability and activity.
