37830-90-3, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.37830-90-3. An updated downstream synthesis route of 37830-90-3 as follows.
5. 0kg adding the compound of formula (IV) in a reaction vessel, 8. 0kg N- bromosuccinimide (NBS), 0. 30kg of azobisisobutyronitrile was added as the reaction solvent chloroform 100L, stirring was warmed to 38 ¡ã C, the reaction system to be stable, then slowly heated to reflux for 2-3 hours, the reaction was completed, cooled to room temperature, insolubles were removed by filtration, the filtrate was atmospheric recovery chloroform, 4 ¡ã C refrigerated overnight and filtered again after crystallization the insoluble matter was removed, and then distilled under reduced pressure collecting ll ¡ã C~120 ¡ã C / 5mmHg fractions, the compound of formula (V) 8. 66kg, yield (mole) 938percent, purity 95.1percent.;
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps.
