One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: phthalazine, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 253-52-1, Name is Phthalazine, molecular formula is C8H6N2
A new photochromic system based on a pyridazinopyrrolo[1,2-b]pyridazine with ultrafast thermal decoloration
The nucleophilic addition of the substituted pyridazines 2a-e to diacetylspirocyclopropene (1) in dry ether solution afforded the dihydroindolizines 3a-e, which undergo ring opening to the betaine 3?a-e after irradation with UV light. Condensation of the diacetyl groups of the dihydroindolizines (DHIs) 3a-e with hydrazine hydrate in a diethyl ether/ethanol mixture gave the new pyridazinopyrrolo[1,2-b]pyridazines 4a-e. Compounds 4a-e showed no photochromism at room temperature or after cooling with liquid nitrogen. However laser flash spectroscopy was successfully used for the determination of both the half-life and absorption maxima of the betaines 4?a-e.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: phthalazine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 253-52-1, in my other articles.
