A study of Oxidative Degradation of AMP for Post-combustion CO2 Capture

The degradation of 2-amino-2-methyl-1-propanol (AMP) has been investigated in the presence of oxygen. AMP was not stable and the overall degradation rate of AMP was close to that of Nmethyldiethanolamine (MDEA) under identical conditions. The primary degradation products identified by GC-MS were acetone, 2,4-lutidine and 4,4-dimethyl-2-oxazolidinone. The oxidative degradation rates of AMP strongly depended upon oxygen partial pressure. The effect of temperature on the overall degradation rates was also measured. No significant catalytic effect was observed when 0.1mM ferrous oxalate (Fe C2O4) and 0.1mM copper sulphate (CuSO4) were added into the AMP solutions, respectively, and the degradation rates of AMP show a weak dependence on a radical initiator. Carbon dioxide (CO2) was found to speed up the overall degradation rate of AMP.

LATERAL METALLATION OF METHYLATED NITROGENOUS HETEROCYCLES

Me groups on nitrogenous heterocycles can be conveniently metallated by a variety of strongly basic reagents to afford synthetically useful carbanions.The negative charge of such anions resides predominantly on the ring N atoms.The site of lithiation on pyridines and quinolines bearing Me groups in both the 2- and 4-positions depends upon the ability of the ring N atom to complex with the metallating agents.Carbanions derived from methylated pyridines, quinolines, naphthyridines, isoquinolines, pyrido<4,3-b>carbazoles, pteridines, pyrido<3,4-b>indoles and quinoxalines are discussed.References are provided describing condensations of these reagents with a variety of both common and uncommon electrophiles.

Exploring SAR features in diverse library of 4-cyanomethyl-pyrazole-3-carboxamides suitable for further elaborations as CB1 antagonists

A chemically diverse library of secondary and tertiary 4-cyanomethyl-1,5-diphenyl-1H-pyrazole-3-carboxamides was synthesized to enable mapping of the SAR, in the eastern amide region, with regard to CB1 antagonist activity, This study was initiated as a prelude to the design and synthesis of possible CB1 antagonists that do not readily pass the blood-brain-barrier. In general a range of modifications were found to be tolerated in this part of the molecule, although polar and especially charged groups did to a degree reduce the CB1 antagonistic activity. Several compounds with single-digit or even sub-nanomolar potency, suitable for further elaboration of the nitrile moiety, were identified.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 126456-43-7 is helpful to your research. Application of 126456-43-7

The synthesis of beta-nitropyridine compounds

Pyridine and a number of substituted pyridines have been nitrated by reaction with N2O5 followed by reaction with an aqueous solution of SO2xH2O or NaHSO3. The dependence of the yields on the pH of the aqueous reaction medium, on the concentration of SO2xH2O-HSO3-, on addition of methanol to the aqueous phase, and on the reaction temperature were investigated.

Synthesis of new chiral auxiliaries for 6pi-azaelectrocyclization: 4- and 7-alkyl substituted cis-1-amino-2-indanols

The synthesis of new chiral auxiliaries, 7-alkyl substituted cis-1-amino-2-indanol derivatives, was established by the Diels-Alder reaction of 1-substituted dienes with cyclopentenone followed by the asymmetric epoxidation of the resulting indene derivatives and then the Ritter reaction. These bulky cis-aminoindanol derivatives are very effective as chiral auxiliaries and nitrogen sources in the asymmetric 6pi-azaelectrocyclization. The corresponding 4-alkyl derivative was also prepared using a similar method.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 126456-43-7, you can also check out more blogs about126456-43-7

Thermodynamic Similarity of Phase-Separation Binary Solutions with a Lower Critical Temperature

The termodynamic similarity of phase-separating binary aqueous solutions with a lower critical solution temperature is discussed.The values of temperature and pressure at the double critical point are used as scales.An analysis of the experimental material on the phase-separation of aqueous solutions of organic compounds has discovered correlations between dimensionless thermodynamic complexes that make it possible to calculate the line of the critical points (LCP) of a solution by the data on phase-separation at atmospheric pressure.The proposed algorithm of calculation is verified by the example of the mixture water/2,6-dimethylpyridine.The calculated and the experimental data for the LCP of this solution demonstrate a satisfactory agreement. keywords Aqueous solutions / Phase-separation / Double critical point / Thermodynamic similarity
