摘要:The synthesis of certain polyester diols (PEDs) is disclosed. This application also discloses the purification and polymerization kinetics of lipid based PEDs. Molecular weight and distribution controls were achieved by initial and induced stoichiometric imbalance and optimization of the purification protocol. Thermal degradation and thermal transition behavior of the PEDs were also investigated by TGA and DSC.

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.

摘要:The compounds of the present invention are obtained by the reaction of carbamoyl lactams (from lactams and polyisocyanates) with polyhydric alcohols or monoamino alcohols in the presence of catalytic quantities of a strong basic catalyst, e.g. an alkali metal alcoholate, at elevated temperatures. The polyols contain urea groups and either ester or amide groups and correspond to formula (I) or (II) (I) (II) The polyols are crystalline, relatively high melting compounds which are used as reactants for the synthesis of polyurethane elastomers, in particular in the form of finely divided components in one-component polyurethane reaction mixtures.
