标题:Process for synthesis of allophanate compounds and compositions including the product thereof
发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

摘要:The invention relates to a process for the oxidation of mesitol with singlet oxygen, which is released from hydrogen peroxide, this release taking place in the presence of a bismuth compound as catalyst. In the process, 2,4,6-trimethylquinol is formed in high yield and selectivity as product, which can be used in further reactions for the synthesis of vitamins and in particular of vitamin A and vitamin E.

标 题:Synthesis of metal 2-ethylhexanoates
发明人：KOVSMAN E P; YANOVSKAYA M I; SOLDATOV B G; MOZAK G V
摘要:A process for synthesizing metal 2-ethylhexanoates includes reaction of metals with a reaction mixture including a carboxylic acid, a low weight aliphatic alcohol, and an electroconductive additive under the action of electric current in an elecrolyzer. In the electrolyzer, an ion exchange membrane divides respective anode and cathode compartments. The metal is introduced in the form of an anode, and is preferably lead or bismuth. The carboxylate is preferably 2-ethylhexanoic acid. The electroconductive additive is preferably a salt of 2-ethylhexanoic acid and an alkali metal or ammonium cation.

标题 :Low temperature synthesis of nanowires in solution

摘要:Methods synthesizing nanowires in solution at low temperatures (e.g., about 400° C. or lower) are provided. In the present methods, the nanowires are synthesized by exposing nanowire precursors to metal nanocrystals in a nanowire growth solution comprising a solvent. The metal nanocrystals serve as seed particles that catalyze the growth of the semiconductor nanowires. The metal nanocrystals may be formed in situ in the growth solution from metal nanocrystal precursors. Alternatively, the nanowires may be pre-formed and added to the growth solution.

标题:Copolymerization of blocked polyisocyanates with bicyclic amide acetals
发明人：GOEL ANIL B
权利人:ASHLAND OIL INC
摘要:A process for preparing polyurethane comprising copolymerization of a mixture comprising a bicyclic amide acetal and a blocked polyisocyanate at a temperature in the range of from about room temperature to about 200° C. is described. The polymerization mixture may also contain polyamines, polyols, and polyepoxides and the polymers resulting from this process are useful as coatings, adhesives, and in elastomer synthesis.
