A complex ester is made by the reaction of a neopentyl-type polyol such as pentaerythritol, trimethylolpropane, or neopentyl glycol; an aromatic polycarboxylic acid such as phthalic, trimellitic, pyromellitic, or mellitic acid, and an aliphatic monocarboxylic acid having from 2-12 carbon atoms, in proportion such that the average number of carbon atoms per acid molecule is from 4-10. The esters have exceptionally low pour points, high viscosity index, and are suitable for lubricating turbine bea...

A chlorhexidine complex is prepared by complexing chlorhexidine (a divalent, cationic antiseptic) with an anionic polymer such as algin or carboxymethylcellulose. The complex is insoluble but can be granulated or crushed to a fine powder. In powdered form the complex forms stable aqueous dispersions. The chlorhexidine complex is suitable for inclusion in oral hygiene compositions such as dentrifrices, and in other antibacterial compositions such as opthalmic under-eye-lid treatment capsules topi...

Platinum complexes of unsaturated siloxanes, substantially free of inorganic halogen and inhibitory compounds, provide superior hydrosilation catalysts when the unsaturated siloxane comprises, per gram-atom of platinum, (i) a combination of one mole of (CH.sub.2 .dbd.CH)((R).sub.2 Si).sub.2 O, and one mole of (CH.sub.2 .dbd.CH) (R).sub.2 SiOSi(R.sub.2)OH; (ii) two moles of (CH.sub.2 .dbd.CH)((R).sub.2 Si).sub.2 O; or (iii) a mixture of (i) and (ii), wherein R is free of aliphatic unsaturation an...

New platinum complex represented by the general formula [I]: ##STR1## wherein R.sub.1 and R.sub.2 are same and represent halogen atom or NO.sub.3, or R.sub.1 is SO.sub.4 and R.sub.2 is H.sub.2 O, or R.sub.1 and R.sub.2 are bonded with each other to form either ##STR2## and the configuration of 1-aminomethyl-2-aminocyclohexane is selected from trans-1, trans-d, cis-1 and cis-d. The compounds of the formula [I] are active against tumor and are expected to be useful as medicaments.

Cis-platinum (II) complexes wherein platinum (II) coordinates 1,2-diamino-cyclohexane (cis-, trans-l-or trans-d-) are disclosed. The complexes exhibit anti-tumor activity.

The invention relates to a complex column comprising a metallic core (1) embedded in a mass of concrete (2). This core (1) is accessible from the outside of the concrete mass (2) at each end of the column for its assembly to a structure.

The disclosure relates to a process for producing an antiviral complex by cultivation of Sirodesmium diversum, to novel components of the complex and to derivatives thereof having antiviral activity, to processes for their manufacture, to pharmaceutical compositions containing the complex, the novel components or their derivatives, and to a method of producing an antiviral effect.

Cuprous bromide and cupric bromide form a 1 to 1 molar complex with N,N'-disubstituted alkylene or cycloalkylene diamines having from 2-3 carbon atoms between the two nitrogen atoms and whose two substituents on the two nitrogens are isopropyl or .alpha.-tertiary alkyl. These complexes have been found to have unique properties as catalysts in the oxidative coupling of phenols to polyphenylene oxides in solvent systems heretofore requiring removal of the water formed as a by-product during the re...

Solid water-soluble aluminum phosphate complexes and binder composition which dissolve in water to give solutions containing aluminum ions and orthophosphate ions in such proportions as to provide an Al:P ratio of substantially 1:1 together with the anions of a carboxylic acid or a mineral oxyacid.

To provide a reagent with excellent stability under storage, which can detect a subject compound to be measured with higher specificity and sensitibity. Complexes of a compound represented by the general formula (I): ##STR1## (wherein R.sub.1 through R.sub.7 independently represent hydrogen atom, halogen atom, alkyl group, aryl group, aralkyl group, sulfonate group, amino group, styryl group, nitro group, hydroxyl group, carboxyl group, cyano group, or aryl azo group; R.sub.1 through R.sub.7 may...
