The alcoholysis of 1,2,2-trimethylpropyl-methylfluorophosphonate

Abstract

The alcoholysis of 1,2,2-trimethylpropyl-methylfluorophosphonate (soman) was examined with a series of alkoxides and in corresponding alcohols: methanol, ethanol, 1-propanol, 2-propanol, 2-methoxyethanol and 2-ethoxyethanol. Soman reacts with the used alkoxides in a second order reaction, first order in each reactant. The kinetics of the reaction between 1,2,2-trimethylpropyl-methylfluorophosphonate and ethanol in the presence of diethylenetriamine was also examined. A third order reaction rate constant was calculated, first order in each reactant. The activation energy, frequency factor and activation entropy were determined on the basis of the kinetic data. .

Ispitana je alkoholiza 1,2,2-trimetilpropil-metilfluorofosfonata (soman) sa nizom alkoksida u odgovarajućim alkoholima: metanol, etanol, 1-propanol, 2-propanol, 2-metoksietanol i 2-etoksietanol. Soman reaguje sa ispitivanim alkoksidima u reakciji drugog reda, prvog reda prema svakom reaktantu. Ispitana je i kinetika reakcije između 1,2,2-trimetilpropil-metilfluorofosfonata i dietilentriamina u etanolu. Reakcija je ukupno trećeg reda, prvog prema svakom reaktantu. Za ispitivane reakcije su izračunate: energije aktivacije, faktori frekvencije i entropije aktivacije. .
