le chatelier's principle is used as a very simple way to predict the effect of a change in conditions on a chemical equilibrium. . however, several studies have reported the violation of this principle, still there is no reported simple mathematical equation to express the exact condition of violation in the gas phase reactions. in this article, we derived a simple equation for the violati...

Isoprenol (3-methyl-3-buten-1-ol) is an important intermediate in the chemical industry and used, for example, production of various scent flavor chemicals. produced from aqueous formaldehyde isobutene separated by distillation mixtures containing formaldehyde, water, process. As forms oligomers with both water isoprenol, these are complex reacting systems, which not easy to separate. Hence, un...
