Photolysis Wavelength Dependence of the Effect of Xenon on the Production of C2*(d3Πg) by Ultraviolet Multiphoton Dissociation

We report on the effect of Xe buffer gas on the C2(d3Πg a3Πu) emission which results from the excimer laser-induced multiphoton fragmentation of acetylene, triethylenediamine (Dabco), and benzene.We find that, upon addition of Xe, normal quenching of this emission occurs for 248-nm (KrF) photolysis of the above molecules, while an unusual enhancement is found for 193-nm (ArF) photolysis.Other radical emmissions resulting from the same process, e. g., CH(A2Δ X2Π) and CN(B2Σ+ X2Σ+), show normal quenching at both wavelengths.The possible mechanisms of this unusual enhancement are discussed.

Synthesis method of triethylene diamine

The invention relates to a synthesis method of triethylene diamine, and solves the technical problems of high cost or certain risk of raw materials, no environmental protection, complex synthesis process, low product yield and the like in the existing production process. The synthesis method comprises the following steps: (1) adding oxalic acid diester into a reaction bottle, dissolving piperazinewith a solvent in advance, adding a catalyst, dropwise adding piperazine dissolved with the solvent at the reaction temperature of 30-80 DEG C, stirring for 1-2 hours, filtering, washing an obtainedfilter cake with the solvent, and drying to obtain an intermediate product, namely dioxytriethylene diamine; (2) adding the dioxytriethylene diamine prepared in the step (1) into a high-pressure reaction kettle, adding a solvent until the dioxytriethylene diamine is completely dissolved, adding a catalyst, tightly covering a kettle cover, sealing, heating to 150-200 DEG C, introducing hydrogen into a high-pressure valve until the pressure reaches 2-10MPa, and continuously introducing hydrogen to maintain the pressure in the reaction process to obtain a triethylene diamine crude product; and (3) carrying out post-treatment to obtain the final product triethylene diamine. The method is applied to synthesis of triethylene diamine.

METHOD FOR PRODUCING BICYCLIC AMINE COMPOUND

PROBLEM TO BE SOLVED: To provide a stable production method for a bicyclic amine compound that inhibits the generation of by-products in the production of a bicyclic amine. SOLUTION: The present invention provides a method for producing a bicyclic amine compound which employs a catalyst comprising an inorganic support and an alkali metal phosphate, and further comprising alkaline earth metal hydroxide and/or hydroxyapatite in an amount of 1.5 wt.% or more and less than 15 wt.% relative to the inorganic support.
