Abstract: This invention relates to novel compositions of matter which are multifunctional amino zirconium aluminum metallo organic complexes which are comprised of a chemically united complex aluminum moiety, a tetravalent zirconium moiety, and a multifunctional amino acid wherein the acid is chemically bound to both the aluminum and zirconium centers.Such compositions are useful in promoting adhesion of adhesives, sealants, and coatings to metal, rubber, glass, plastic, coatings, and wood thereby enhancing strength properties and prolonging useful service life when such products are exposed to aggressive environments.Futher described is the specific process for the preparing of such compositions in organic media with desirable stability of the metal centers toward polymerization and related hydrolysis.

Abstract: Described are novel bimetallic complexes particularly useful as homogeneous catalysts for the metathesis of alkynes and metathesizable functionally substituted alkynes, and methods for the preparation of such complexes. The complexes are formed from (i) a Group VI-B metal compound having (a) quadruple metal to metal bonds between a pair of Group VI-B metal atoms at least one of which has an atomic number above 24, and (b) four monovalent anions with a k.sub.A greater than 10.sup.-14, and (ii) a Group III-A phenoxide, a Group III-A alkoxide or a Group IV-B metal alkoxide. Displacement of two of the anions appears to occur during formation of the complex. Usually the complexes can be produced very easily and quickly. All that is required is to establish intimate contact between components (i) and (ii), preferably in an innocuous liquid organic solvent. Addition of a small amount of a nitrile gives a faster and cleaner reaction. In some cases use of slightly elevated temperatures is desirable.

Abstract: An aromatic solution of the compound CuAl(CN)Cl.sub.3 alone or with additional solid CuAl(CN)Cl.sub.3 is used for the separation of some unsaturated compound (olefin, acetylene or carbon monoxide) from a feedstream.The feedstream is contacted with the solvent to form a complex of the ligand (olefin, acetylene or carbon monoxide). The feedstream is then separated from the solvent. The solvent is then treated with some combination of heat and lowered pressure to separate the ligand from the solvent. The ligand poor solvent is then recycled to contact fresh feedstream.

Abstract: This invention relates to novel compositions of matter which are mixed metal metallo-organic complex agents comprised of a chemically united complex aluminum moiety and a tetravalent zirconium moiety. The specific process for preparing such compositions in organic/solvent media with desirable hydrolytic stability is described.Further described are compositions of matter wherein the aforementioned metallo-organics are employed to chemically modify the surface of fibrous and particulate inorganic substances and certain organic particulates, thereby resulting in hydrophobic, organophilic fibers and particles having improved rheological properties which facilitate higher filler (fiber) loading levels and serve to enhance the physical properties of composite articles and coatings formed therewith.
