Puyang Blue Star was a key investment promotion project implemented in Puyang in 2016. Our butadiene devices use BASF's technology which are world-class in terms of security, environment-friendliness and energy conservation, etc. In 2020, we pursued high-quality development, strove for development with confidence and extended our industry chain dependent upon butadiene - our main product according to requirements of the municipal committee and government. We invested in constructing latex project with a capacity of 100,000t/year, and this project was put into production in October 2021. These devices are domestically advanced and their production processes are leading in the industry. They have developed more than 10 series of Carboxyl butyronitrile latex and Carboxylic styrene butadiene latex . They are widely applied in industries of disposable medical gloves, papermaking, architectural coatings, carpets, tyres, non-woven fabrics, leather and cement etc. Puyang Blue Star New Mat

The tandem catalysis of ring-closing metathesis/atom transfer radical reactions was investigated with the homobimetallic ruthenium-indenylidene complex [(p-cymene)Ru(μ-Cl) 3 RuCl(3-phenyl-1-indenylidene)(PCy 3 )] (1) to generate active species in situ. The two catalytic processes were first carried out independently in a case study before the whole sequence was optimized and applied to the synthesis of several polyhalogenated bicyclic γ-lactams and lactones from αω-diene substrates bearing trihaloacetamide or trichloroacetate functionalities. The individual steps were carefully monitored by 1 H and 31 P NMR spectroscopies in order to understand the intimate details of the catalytic cycles. Polyhalogenated substrates and the ethylene released upon metathesis induced the clean transformation of catalyst precursor 1 into the Ru(II)-Ru(III) mixed-valence compound [(p- cymene)Ru(μ-Cl) 3 RuCl 2 (PCy 3 )], which was found to be an efficient promoter for atom transfer radical reactions under t

The anion of the title compound, simply generated in the presence of catalytic amount of triethylamine, acts as nucleophilic acylating equivalent of formaldehyde reacting with both common electrophilic olefins or aldehydes to give moderate to good yield of Michael or aldol adducts respectively, which are easily hydrolized by dilute acid at ambient to temperature to afford the corresponding aldehydes. https://www.lookchem.com/CASDataBase_759-05-7.htm

Treatment of a thallium(I) carboxylate with 1 molar equivalent of bromine gives the corresponding thallium(III) carboxylate dibromide.High yields of primary alkyl bromides are obtained if the thallium(III) carboxylate dibromide is treated with 0.5 mol equiv. of bromine in refluxing carbon tetrachloride.Pyrolysis of the thallium(III) derivative in the absence of added bromine gives a low yield of the corresponding alkyl bromide.The use of thallium(I) carboxylates for the preparation of alkyl bromides in high yields is limited to the salts of primary carboxylic acids.A simple procedure for the preparation of alkyl bromides from carboxylic acids using thallium(I) carbonate has been developed. https://www.lookchem.com/CASDataBase_75-26-3.htm
