A process for their preparation involving an amine displacement reaction is also described. A method of use and pharmaceutical compositions containing the subject compounds are also described.

This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particulate 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-phosph...

Disclosed herein are compounds of the general formula ##STR1## wherein x and y are integers from 3 to 9, x and y together equal 12, one Z is hydrogen and the other Z is a carboxylic acid group, and R.sub.1 and R.sub.2 are fatty acid groups. A process for introducing approximately one carboxylic acid group per triglyceride molecule in vegetable oils has been developed, and the resulting acid adduct forms soaps with attractive properties. The process comprises first conjugation of the double bonds...

An imidazole-isocyanuric acid adduct having the following formula is disclosed: ##STR1## wherein R.sub.1 is a member selected from the group consisting of a hydrogen atom, a .beta.-cyanoethyl group and a .beta.-[3,5-diamino-s-triazinyl-(1)]-ethyl group, R.sub.2 stands for a monovalent hydrocarbon group having up to 17 carbon atoms, R.sub.3 is a member selected from the group consisting of a hydrogen atom and an alkyl group having up to 4 carbon atoms, with the proviso that when R.sub.1 is a hydr...

The subject invention relates to polyol compositions comprising the reaction product prepared by reacting from 4 to 9 moles of propylene oxide per mole of toluenediamine by weight at temperatures greater than 140.degree. C. in the presence of at least 0.6 parts of alkali metal hydroxide per 100 parts by weight of toluenediamine, with the proviso that at least 0.8 part by weight of alkali metal hydroxide is used if the toluenediamine is 2,4-toluenediamine, or 2,6-toluenediamine, or mixtures there...

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 infestations of the pinworms Syphacia obvelata and Aspicularis tetraptera in mammals. Several of the compounds are also effective against the tapeworm Hymenolepsis nana in mammals.

A novel sulfur-based adduct formed by reacting sulfur with a diene-containing by-product hydrocarbon mixture available from petrochemical operations and/or from coal processing. The adduct is a reaction product of sulfur and each of the dienes contained in the by-product mixture. Also disclosed is a road surface composition containing this adduct as an asphalt extender or as a replacement for asphalt, and there are also disclosed other compositions containing this adduct such as sulfur cements, ...
