Abstract: Oil-soluble combinations of (A) ethylene polymer or copolymer, (B) normal paraffinic wax composed of normal hydrocarbons whose average molecular weight is within the range of from 300 to 650, and (C) nitrogen compounds, such as amides, amine salts and ammonium salts, of carboxylic acids or anhydrides, are useful in improving the cold flow properties of distillate hydrocarbon fuel oils. Preferably, the wax contains n-paraffins ranging from C.sub.23 to C.sub.37 inclusive. If desired, the combination can be usefully stabilized by the addition of one or more compatibility additives, i.e. a polymer having alkyl side chains of 6 to 30 carbon atoms and derived from carboxylic acid esters and/or olefins or C.sub.8 -C.sub.18 alkanol, e.g. tridecyl alcohol or mixtures of said polymer and alkanol.

Abstract: Certain substituted aralkylanilines in which the aromatic aniline ring carries, at the para position to the amino function, a substituent which comprises a carboxylic acid, salt or ester, an alkyl, hydroxyalkyl, cyano or acyl group, have hypolipidaemic activity.
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: New compounds of the formula (I) ##STR1## wherein R.sub.1 and R.sub.2 each is a saturated or unsaturated, straight-chained or branched alkyl group, an aralkyl group, a saturated or unsaturated cycloalkyl group or an aryl group, orR.sub.1 and R.sub.2 together with the adjacent nitrogen atom forms a substituted or unsubstituted heterocyclic group with or without a further oxygen or nitrogen heteroatom, andR.sub.3 is hydrogen or an acyl group derived from a C.sub.1-18 carboxylic acid. The compounds are prepared by reducing the corresponding nitro compounds of the formula (II) ##STR2## and optionally acylating the obtained product. The compounds of the formula (I) and their acid addition salts and quaternary ammonium salts are active primarily in the induction of liver microsomal enzymes, but they also possess valuable antipyretic activity and a yohimbine lethality increasing effect characteristic of antidepressants.
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.
