    摘要: When a salt of an amine and an optically active diacyltartaric acid, or a diastereomer salt of an optically active amine and an optically active diacyltartaric acid, obtained by optically resolving a racemic amine using the optically active diacyltartaric acid, is salt-exchanged with an acid aqueous solution, the optically active diacyltartaric acid is added in the acid aqueous solution beforehand.Furthermore, a raw material containing a racemic amine and an optically active diacyltartaric acid is optically resolved, and the diastereomer salt of the optically active amine and the optically active diacyltartaric acid respectively of one isomer type, is separated. The obtained diastereomer salt is dissociated using an acid aqueous solution containing the optically active diacyltartaric acid, for recovering the optically active diacyltartaric acid, and the obtained optically active diacyltartaric acid is recycled into an optical resolution step as a raw material of the optical resolution step.

    摘要: A process for the production of hydroxy fatty acids and novel estolide compounds, each of which may be used as lubricants, greases, plasticizers and printing inks, as well as in cosmetics. The estolides are of the formula (I): ##STR1## wherein R.sub.1 is selected from C.sub.6 -C.sub.16 hydrocarbons which may be saturated or unsaturated, and branched or straight chain, and optionally substituted, such as with one or more hydroxy groups; R.sub.2 is independently selected from C.sub.2 -C.sub.17 hydrocarbons which may be saturated or unsaturated, and branched or straight chain, and optionally substituted, such as with one or more hydroxy groups; A is selected from C.sub.3 -C.sub.14 hydrocarbons which may be saturated or unsaturated, and branched or straight chain, and optionally substituted; n is greater than or equal to 1; y is an integer from 3-13; x is 1 or 2; and . . . designates a single or double carbon/carbon bond. Formation of these estolides is by catalytic reaction of unsaturated fatty acids, especially .DELTA..sup.5 and .DELTA..sup.6 unsaturated fatty acids. Following their formation, the estolides may be recovered for subsequent use, or in the alternative, they may be hydrolyzed to produce hydroxy fatty acids.

    摘要: The invention relates to a salt of a basic histamine H.sub.2 -receptor antagonist of formula (I) ##STR1## and a complex of bismuth with a carboxylic acid selected from tartaric acid, citric acid and alkyl citric acids, or a solvate of such a salt, whereinR.sup.1 represents a group of formula ##STR2## where R.sup.3 represents methyl or the group (CH.sub.2).sub.2 CONR.sup.4 R.sup.5 in which R.sup.4 and R.sup.5 both represent ethyl groups;R.sup.2 represents a hydrogen atom or, when R.sup.1 is the group --C(.dbd.CHNO.sub.2)NHCH.sub.3, R.sup.2 may also represent a methyl group; andn is 3 and X is oxygen, or n is 2 and X is CH.sub.2 or sulphur;with the provisos that(i) when R.sup.1 represents ##STR3## then X is sulphur and n is 2: (ii) when R.sup.1 represents --C(.dbd.CHNO.sub.2)NHCH.sub.3 and R.sup.2 is hydrogen, then X is oxygen and n is 3 or X is CH.sub.2 and n is 2; and(iii) when R.sup.1 represents --C(.dbd.CHNO.sub.2)NHCH.sub.3 and R.sup.2 is methyl, then X is oxygen and n is 3 or X is sulphur and n is 2.The salts and solvates thereof are useful in the treatment of gastro-intestinal disorders, such as peptic ulcer disease, gastritis and non-ulcer dyspepsia.
