Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 4020-99-9, Name is Methoxydiphenylphosphine, COA of Formula: C13H13OP.
Alkoxyphosphonium ions. 5. Kinetics of the Michaelis-Arbuzov intermediate
Rates of formation and destruction of the alkoxyphosphonium ion, the intermediate in the Michaelis-Arbuzov reactions of some methyl esters of trivalent phosphorus acids with methyl iodide, are followed by a conductivity method in the solvent propylene carbonate.Specific conductances of the unstable intermediates are well estimated through stable model salts.Rate constants for both the alkylation of the reagent and the dealkylation of the intermediate are obtained.The conductivity time curves are simulated by adjusting rate constants for two sequential second order reactions, assuming no ion pairing at the concentrations used.In these measurements of the intermediate only, there is no rate-determining step; for the overall rection the first step is in most cases rate-determining.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.COA of Formula: C13H13OP. In my other articles, you can also check out more blogs about 4020-99-9
