One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 38028-67-0, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 38028-67-0, Name is 2-Ethoxypyrazine, molecular formula is C6H8N2O

A kinetic study has been made of the first-order thermal decomposition of the title compounds into ethylene and the corresponding aza-substituted pyridines, between 650 and 713 K.The relative elimination rates at 650 K are (2-ethoxypyridine = 1): 0.545, 10.0, 1.03, 1.12, 9.68, and 3.28, respectively.The electronic effects of the aza ‘substituent’ are small, and a more important factor appears to be the C-N ?-bond order; this latter accounts for the high reactivity of the pyridazines.The effects of the chloro substituent and of the aza ‘substituent’ are explicable in terms of a balance between electron withdrawal from the C-O bond (producing deactivation) and from the nitrogen involved in the cyclic transition state (producing deactivation).The effects of the chloro substituents confirm that the most important step of the reaction is breaking of the C-O bond.The statistically corrected rate (per ring nitrogen) of 2-ethoxypyrimidine is unexpectedly low.This may reflect difficulty in achieving the coplanar transition state in which the lone pairs in the s-orbitals of oxygen and the nitrogen not involved in the elimination are brought into close proximity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

The electronic structures of C4H2Cl2N2 isomers have been studied by HeI photoelectron spectroscopy (PES) combined with the outer valence Green’s function (OVGF) calculations at 6-311++G(d,p) basis sets. The vertical first ionization potentials for 2,6-dichloropyrazine, 2,3-dichloropyrazine, 4,6-dichloropyrimidine and 3,6-dichloropyridazine are determined to be 9.93, 9.89, 10.45 and 10.07 eV, respectively, and the PE spectra were assigned based on molecular orbital analysis and by comparison with related compounds. The effects of chlorine substituent and different positions of nitrogen atoms in these C4H2Cl2N2 isomers have been carefully analyzed by comparing the C4H2Cl2N2 isomers with their matrixes (pyrazine, pyridazine, pyrimidine). The inductive effect of chlorine substituent leads to the stabilization of the nitrogen lone pair orbitals. The resonance effect predominates over the inductive effect, and the consequence is the destabilization of the pi orbitals. Owing to the different positions, the effects of nitrogen atoms are different and lead to the different sequence of pi orbitals.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 3,6-Dichloropyridazine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 141-30-0, name is 3,6-Dichloropyridazine. In an article，Which mentioned a new discovery about 141-30-0

A series of alkyl (1-3), aryl (6), and benzo-annulated (4,5) heteroaromatic triphenylene analogues with B2N2C2 cores have been synthesized via chelation of pyridazine derivatives using difunctional Lewis acidic diborabiphenyl precursors. In contrast to triphenylene, NICS(1) calculations on 1 suggested high aromaticities for the central (-11.3 ppm) and outer borabenzene rings (-7.7 ppm), along with nonaromatic behavior for the pyridazine ring (-0.7 ppm). Crystal structure analyses supported this analysis. When the a- and c-faces of the pyridazine moiety were free of substitution (1, 3), planar structures resulted, but upon substitution, a twisted B 2N2C2 core was observed due to steric repulsion of neighboring hydrogen atoms (e.g., 5). The increase of steric bulk from H (1) to ?Pr (3) in the planar species was found to result in a dimeric, head-to-tail herringbone packing motif, held together by close intermolecular B…N interactions of 3.39 A. One-electron reduction by Cp*2Co was found to afford the radical anions of 3 and 5, which were characterized by broad, featureless singlets in the EPR spectra; [3] .-[Cp*2Co]- was characterized by X-ray crystallography. While the planar structures (1-4) were observed to possess weak fluorescence (PhiF = 0.02-0.08) with either yellow-orange (ca. 555 nm) or green emission (521 nm), the twisted structures (5, 6) were found to be nonfluorescent.
