METHOD OF PRODUCING TERTIARY AMINE OR TERTIARY AMINE DERIVATIVE

PROBLEM TO BE SOLVED: To provide a method of producing tertiary amine or tertiary amine derivative with high selectivity. SOLUTION: In the method of producing tertiary amine or tertiary amine derivative, a reaction system including: an organic chemical raw material containing at least one kind of group selected from -NH2, -NH2 HCl, >NH and >NH HCl, a nitrogen atom contained in the group bounding to a carbon atom; aliphatic alcohol having 1 to 20 carbon atoms; and a catalyst where a carrier containing titanium oxide carries a silver component (metal silver or silver compound), is irradiated with light, and the group in the organic compound raw material is converted to -NR02 or >NR0, ( R0 is an aliphatic hydrocarbon group having 1 to 20 carbon atoms derived from the aliphatic alcohol). The percentage content of the silver in the catalyst is 0.5 to 10 mass% with respect to the titanium oxide. COPYRIGHT: (C)2015,JPOandINPIT

Amine catalyst for producing polyurethane and polyisocyanurate

An amine catalyst-for production of a polyurethane and a polyisocyanurate is provided which comprises a quaternary ammonium compound represented by General Formula (1): where R1 to R6 are independently a linear or branched saturated hydrocarbon group of 1 to 4 carbon atoms; R7 and R8 are independently a linear or branched, saturated or unsaturated hydrocarbon group of 2 to 12 carbon atoms; n is a number of 0 to 3 provided that at n=o any one of R1, R2 and R3, and R5 and/or R6 may be linked together to form a heterocycle, or at n=1, 2, or 3, R5 or R6 and R4 may be linked together to form a heterocycle; A is a carbonate group or an organic acid group; and X is number of 1 to 2. The catalyst has high activity in formation of polyurethane foams and polyisocyanurate foams, having less odor, and producing foams of high fire retardance, having high curability, high retarding effect, and low corrosiveness.

Transalkylation Reaction. Homogeneous Catalytic Formation of C-N Bonds

We have performed kinetic and mechanistic studies on homogeneous ruthenium-catalyzed transalkylation of tertiary amines.From these studies we have derived a kinetic expression for transalkylation catalysis based on initial reaction rates.We find that transalkylation proceeds most efficiently in alcoholic solvents (e.g., MeOH or EtOH), under a slight pressure of CO, with a mixed-metal, iron-ruthenium catalyst.The mechanism appears to be in one which a metal cluster of at least two and most probably three atoms binds the amine through insertion into an α C-H bond to give a metallazacyclopropane or metal-iminium complex.Nucleophilic attack by free amine on the complex, or an immediate derivative, follows, and subsequent rearrangement of the intermediate formed gives transalkylation products.The catalyst system has been tested as a synthetic tool for the oligomerization and cyclization of tertiary diamines.These preliminary studies have been quite succesful.Thus, N,N,N',N'-tetramethylethylenediamine can be transformed into Me3N and N,N'-dimethylpiperazine with good conversion and high selectivity.N,N,N',N'-Tetraethylethylenediamine can be transformed into Et3N and the linear, perethyl, ethylenediamine dimer, trimer, tetramer, and pentamer with excellent conversion.
