摘要： A white light emitting material having a chemical structural formula represented by formula (I), a preparation method thereof and application thereof. The preparation method comprises subjecting tris(4-iodophenyl)amine and 4-methoxyphenylacetylene or tris(4-iodophenyl)amine and methyl 4-ethynylbenzoate to a coupling reaction under protection of a protective gas and catalysis of a Pd/Cu mixed catalyst, to obtain the white light emitting material. A novel temperature-sensitive light emitting material is synthesized through a one-step method. The material is applied to the field of diode luminescence based on the temperature-sensitive characteristic. White light luminescence can be finally realized only by reasonably controlling the temperature and duration time during heating a substrate. Compared with the existing art, the method greatly saves raw material costs and manufacturing process costs, and provides a novel idea and strategy for use of a white organic light emitting diode.

摘要： Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, as described herein. In particular, the present disclosure describes a process for the production of a nitrile intermediate by reacting a tetra-amino compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce the chelators at a high yield and/or a high purity.

摘要： N-alkyl, N-alkenyl, N-cycloalkyl, N-aryl amino or imino propionic acids with an alkyl chain ranging from 6 to 18 carbons, or alkenyl chain from 8 to 30 carbons, are obtained from a reaction process in the absence of solvent at a temperature range from 30 to 180° C. and a time of 1 to 10 hours at atmospheric pressure. Formulations composed of N-alkyl or N-alkenyl or N-cycloalkyl or N-aryl amino or imino propionic acids, polyethers derived from propylene oxide or ethylene oxide or copolymer thereof and a solvent consisting of aromatic compounds such as toluene or xylene, diesel or gasoline or alcohols such as isopropanol and ethanol, or mixtures thereof, are obtained inhibit ferrous metal corrosion of pipelines and storage tanks and transport crude oil and liquid fuels. A method inhibiting corrosion of ferrous metals adds an effective amount of the corrosion inhibitor to a petroleum based material such as crude oil and liquid fuels such as gasoline, diesel fuel, and aviation fuel.

摘要： The invention is directed to systematic synthetic and testing strategies for .alpha.-keto acids, esters and amides. The method of synthesis comprises (A) reacting (cyanomethylene)triphenylphosphorane with a carbonyl compound selected from carboxylic acids (RCOOH) and acyl chlorides (RCOCl) to make a cyano keto phosphorane, (B) oxidizing said phosphorane and (C) reacting the oxidized product with a nucleophile (NuH) to make the product .alpha.-keto acid, ester or amide. Systematic synthesis and testing are achieved by a modular approach in which arrays of molecules are generated by variation of R and Nu.
