Thermal decomposition of acetonitrile. Kinetic modeling

Abstract

are computed with this scheme at intervals and are compared with the values reported 50 K in the literature. Except for acrylonitrile and propyl nitrile at the high-temperature end of the study, very good agreement between the calculation and the experiment is obtained. A sensitivity spectrum of the kinetic scheme is shown and a discussion of the overall mechanism is presented.

Nitridation of δ-alumina to aluminum nitride under a flow of ammonia and its mechanism

“…Figure 4 shows the change in IR spectra of the gas evolved as the temperature was increased from 1000 to 1200°C. The peaks assigned to HCN and CH 4 , which are the major decomposition products of CH 3 CN, 16) were observed along with the peaks assigned to CO. At 1200°C the peaks assigned to HCN and CH 4 were intense and very weak, respectively, indicating that HCN is involved in the nitridation of ¤-Al 2 O 3 in the NH 3 C reaction system. This nitridation mechanism for the NH 3 C reaction system will also be applicable to the NH 3 HC reaction system.…”

Generation of radical species in CVD grown pristine and N-doped solid carbon spheres using H2 and Ar as carrier gases

“…During post doping of the CSs, acetonitrile decomposes at high temperatures to give propyl nitrile and other radicals. 74 The radicals decompose further to give nitrogen atoms that are incorporated on the carbon nanostructure edges or in the matrix by substitutional doping. In the case of CSs obtained using H 2 , there exist defect sites which further reacts with the radicals generated by the acetonitrile decomposition resulting in incorporation of nitrogen on the edges.…”

Pyrolysis and Combustion of Acetonitrile (CH{sub 3}CN)

“…86% at 1727°C. Recently, another reaction scheme for the pyrolysis of acetonitrile has been developed containing 23 species and 43 reactions, which predicts the yields of the major and minor products in the temperature range from 1077 to 1677°C (Lifshitz and Tamburu 1998). There was very good agreement between the model and the experimental data.…”
