标题:Activation Conditions Play A Key Role In The Activity Of Zeolite Cay: NMR And Product Studies Of Brønsted Acidity
摘要:Cay,Activated Under Different Conditions,Was Characterized With H-1,(31)P,And H-1/27Ai Double Resonance Mas NMR. The H-1 Mas NMR Spectra Of Cay,Calcined In An Oven At 500 Degrees C,Shows Resonances From H2O (Bound To Ca2+ And The Zeolite Framework),Caoh+,Aluminum Hydroxides,Silanols,And Bronsted Acid Sites. No Evidence For Lewis Acidity Is Observed On Adsorption Of Trimethylphosphine,And An Estimate Of Approximate To 16 Bronsted Acid Sites Per Unit Cell Is Obtained For This Sample. Cay Activated In An Oven At Higher Temperatures Contains Less Water,But All The Other Species Are Still Present. In Contrast,Cay Activated By Slow Ramping Of The Temperature Under Vacuum To 500 Or 600 Degrees C Shows A; Much Lower Concentration Of Bronsted Acid Sites (<1/unit Cell). Again,No Evidence For Lewis Acidity Was Observed. These NMR Results Have Been Utilized To Understand The Very Different Product Distributions That Are Observed For Reactions Of 1,1-And 1,2-Diarylethylenes In Zeolite Cay Activated In An Oven (In Air) And Under Vacuum. Samples With High Concentrations Of Bronsted Acid Sites React Stoichiometrically With These Sites,Yielding Diarylalkanes. At Low Concentrations,The Bronsted Acid Sites Can Act Catalytically Resulting In Isomerization Reactions.

摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.

摘要:The present disclosure provides a process for the selective synthesis of dimethyl carbonate 0 (DMC). More particularly, the present disclosure provides a process for inhibiting catalyst deactivation in a process for selective DMC synthesis. The process is particularly characterized by conducting the process in the presence of a small quantity of air. Further provided herein is a system for facilitating the said process. The process and the system (Figure 1) of the present disclosure prolong the life of the catalyst by virtue of introduction of air into the reactor.

摘要:Disclosed herein are heterocyclic arynes and methods for preparing the same. Heteroarynes such as 5-membered O- or N-heterocyclic arynes have been considered inaccessible due to ring strain associated with the triple bond. The methods described herein demonstrate that these arynes can be successfully prepared through the utility of pi-backbonding from a transition metal. Synthetic utility of this method has been demonstrated by the facile synthesis and functionalization of heterocycles using these heteroaryne building blocks.
