Antibiotic-natural polysaccharides polymer adducts based on non-covalent and non-ionic bonds, with an improved profile of activity compared with the corresponding antibiotic.

Novel adducts of a carbamoyl sulphoxide and urea having the formula ##STR1## and adducts of the said carbamoyl sulphoxide and an organic compound having the grouping ##STR2## wherein R is substituted or unsubstituted aryl, alkyl or alkenyl; R.sub.1 and R.sub.2, which may be the same or different, are H, substituted or unsubstituted alkyls, alkenyls or aryls, or aliphatic groups that, bound to one another in the form of a chain --(CH.sub.2).sub.p --(X).sub.n --(CH.sub.2).sub.q -- (in which p = 1,...

This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particular fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins. The titanate-phosphi...

The adducts of monoepoxides with selected diamines, preferably m-xylylenediamine, are useful as curing agents for the curing of epoxy resin compositions at very low temperatures (25.degree.-50.degree. F., -4.degree. to 10.degree. C.).

Compositions containing one or more surfactants in combination with sulfuric acid and one or more of certain chalcogen-containing compounds in which the chalcogen compound/H.sub.2 SO.sub.4 molar ratio is below 2. These compositions contain the mono-adduct of sulfuric acid which is herbicidally active for controlling vegetation. Suitable chalcogen-containing compounds have the empirical formula ##STR1## wherein X is a chalcogen, each of R.sub.1 and R.sub.2 is independently selected from hydrogen,...

Amines which are compounds of the formula I: ##STR1## where R is a C.sub.6-20 hydrocarbon; X is --NR.sub.1 -- or --O--; each R.sub.1 is independently H or --[(CH.sub.2).sub.1-4 ]COOH or a C.sub.6-20 hydrocarbon; n is 1, 2 or 3; and which contains at least one (CH.sub.2).sub.1-4 COOH group; or salt thereof are useful in inhibiting corrosion of metals in a marine or freshwater environment e.g. in oil- and gas-field applications since they show relatively low toxicity to marine organisms.

There are disclosed novel avermectin compounds wherein the glycosyl side chain is substituted with, or replaced by an alkyl ester group in a Reformatsky reaction. The compounds are prepared by reacting an .alpha.-halogenated ester to a 4'-, 4"- or 13-keto-avermectin derivative in the presence of a reducing agent. The avermectin compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural p...

Control of parasitic worm (helminth) infestations in warm-blooded animals including poultry, swine, cattle, sheep and goats by administering substituted quinoxaline adducts to infested animals. In particular, certain adducts of quinoxaline-1,4-dioxides are capable of eliminating ingestations of the pinworms Syphacia obcelata and Aspicularis tetraptera in mammals. Several of the compounds are also effective against the tapeworm Hymenolepsis nana in mammals.

Organophilic polyphenolic materials which are effective fluid loss control additives for oil base well-working fluids are prepared from a polyphenolic material and one or more phosphatides. Preferred phosphatides are phosphoglycerides obtained from vegetable oils, most preferably commercial lecithin. Preferred polyphenolic materials comprise one or more of: humic acid; lignosulfonic acid; lignins; phenolic condensates; tannins; the oxidized, sulfonated, or sulfomethylated derivatives of these po...
