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.

A method for thermally cracking Diels-Alder adducts and for altering organic streams containing Diels-Alder adducts using controlled cavitation conditions.

Adducts which are obtainable by reacting cycloaliphatic or heterocycloaliphatic polyamines containing at least two primary groups with polyfunctional epoxides containing more than two epoxy groups per molecule in such amounts as to supply 10-100 equivalents of active hydrogen atoms bound to amino nitrogen per one epoxide equivalent, are suitable hardeners for epoxy adhesives, especially adhesives for metals and thermosetting plastics.

Azlactone-functional Michael adducts are disclosed which are the Michael reaction products of 2-alkenyl azlactones and Michael donors selected from carbon and nitrogen nucleophiles. Reaction products which contain a plurality of azlactone groups are useful as step growth monomers in adhesives, sealants, and coatings.

A process is provided for selectively separating oxygen from an oxygen-containing fluid stream by bringing said fluid stream into contact with a high capacity solid state cyanocobaltate complex in a non-aluminosilicate environment represented by the chemical formula: where: A is an alkali, alkaline earth, transition, or Group 12 metal atom; Z is 1, 2 or 3; n is any number from 3 to 5; X is n-2; p is any number from greater than zero to 6; and S is a ligand which is capable of coordinating with A...

There is disclosed a method of forming a urea adduct complex by reacting an aluminum hydrogen phosphate complex which is normally unstable in solution at a pH greater than 2.5 with sufficient urea that no precipitation of alumina occurs on addition of ammonia, and adjusting the pH of the resultant urea adduct complex with ammonia to a value of from 2.5 to 10. The urea adduct complexes of the invention are fire retardants and fire quenching agents and are useful as agricultural adjuvants.

New amidine/isocyanate adducts are particularly useful as catalysts for hardening epoxy resins, in particular pulverulent coating compositions based on epoxy resins. New bicyclic amidines are excellent starting materials for manufacturing these amidine/isocyanate adducts.
