Abstract: The present specification relates to novel 9-deoxy-9-methylene-trans-2,3-didehydro-PGF compounds with improved pharmacological properties. While these compounds are useful in inducing a wide variety of prostaglandin-like pharmacological effects, they are specifically useful as regulators of procreation and fertility.

Abstract: This invention relates to a novel aromatic diamine and more particularly to the use of said diamine for the preparation of thermally stable high-molecular weight polymers including, for example, polyamides, polyamideimides, polyimides, and the like. This diamine is obtained by reacting a stoichometric amount of a disodium salt of 2,2-bis(4-hydroxyphenyl) hexafluoropropane with 4-chloronitrobenzene to obtain an intermediate, 2,2-bis[4-(4-nitrophenoxy)phenyl] hexafluoropropane, which is reduced to the corresponding 2,2-bis[4-(4-aminophenoxy)phenyl] hexafluoropropane.

Abstract: A process is described for the isolation of 4,4'-diaminodiphenylmethane in substantially pure form (of the order of 99% purity) from admixtures thereof with the corresponding 2,4'-isomer and 2,2'-isomer. The dihydrochloride of the isomeric mixture of diamines is heated in the presence of an inert organic solvent with a mixture of isomers of the free diamine, in which the amount of the 4,4'-isomer is at least equal to that of the 2,4'-isomer in the dihydrochloride isomeric mixture. The isomeric mixture of the diamines may be employed in the form of a mixture of polymethylene polyphenyl polyamines containing a major portion of said diamines. The reaction product consists of the insoluble dihydrochloride of substantially pure 4,4'-diaminodiphenylmethane and a solution which is enriched in 2,4'-isomer as compared with the starting mixture of diamines.
