Gas-phase pyrolysis of diethyl methylphosphonate: Gas-phase pyrolysis of diethyl methylphosphonate. Zergers, E. J. P.; Fisher, E. M. 683-08-9 and 1610-33-9 are also occured in this study.

ISSN: 0010-2202. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Flow reactor pyrolysis studies of di-Et methylphosphonate (DEMP) in nitrogen were conducted at 802-907 K, to gain insight into decompn. mechanisms relevant to incineration of organophosphorus chem. warfare agents. Expts. were conducted in a quartz-lined turbulent flow reactor with residence times of 15-125 ms. Two techniques are used to identify products: FTIR spectroscopy for volatile compds., and GC/mass spectrometry preceded by derivatization for products trapped in a liq.-N bath. C2H4, EtOH, Et methylphosphonate, and methylphosphonic acid were identified as products; ethylene, ethanol and DEMP were quantified using FTIR. The mean ratio of C2H4 to EtOH is 1.66. Rates of DEMP decompn. and product formation are independent of loading and reactor diam. The temp. dependence of the overall DEMP decompn. rate const. was k [s-1] = 2.9 x 1016 exp(-59.2 [kcal. mole-1]/(R T)). Bond scission and ring transition state mechanisms can explain the formation of C2H4 and EtOH from DEMP and Et methylphosphonate. .
