Methyl nitrite

Methyl nitrite burns vigorously with oxygen at atmospheric pressure giving a very fast flame. It will also support a very feeble, slow self-decomposition flame [122—124]. The latter is orange-red and the burning velocity [125], relative to the unburnt gas at 18 °C, is about 3.5 cm.sec , while the global activation energy [126] is 37.5 kcal.mole . The final products of the flame are represented by the stoichiometric equation [Pg.485]

CH3ONO = 0.72CO + O.56H2 + 0.54NO + O.42H2O + O.I4N2 + [Pg.485]

The flame temperature calculated on the basis of this stoichiometry is about 1100 °C, in excellent agreement with the observed value [127]. [Pg.485]

Example 86 A 0.10 mole amount of the starting 3-(4-hydroxyphenyl) propylene, 0.25 mole of methyl nitrite, 0.5 liter of methyl alcohol, and 0.006 mole of a palladium chloride catalyst were charged into a reaction vessel. Then, the reaction was carried out at a temperature of 20.degree. C. for 1.5hours."... [Pg.83]

A solution of chilled dilute H2SO4 (C) is dropped in a solution af methanol, water and NaN02 (B), then methyl nitrite is generated. [Pg.84]

The oxidation of terminal alkenes with an EWG in alcohols or ethylene glycol affords acetals of aldehydes chemoselectively. Acrylonitrile is converted into l,3-dioxolan-2-ylacetonitrile (69) in ethylene glycol and to 3,3-dimetho.xy-propionitrile (70) in methanol[28j. 3,3-Dimethoxypropionitrile (70) is produced commercially in MeOH from acrylonitrile by use of methyl nitrite (71) as a unique leoxidant of Pd(0). Methyl nitrite (71) is regenerated by the oxidation of NO with oxygen in MeOH. Methyl nitrite is a gas, which can be separated easily from water formed in the oxidation[3]. [Pg.31]

In addition to the Hquid-phase -butyl nitrite (BN) process, UBE Industries has estabHshed an industrial gas-phase process using methyl nitrite (50—52). The oudine of the process is described in Eigure 4 (52). This gas-phase process is operated under lower reaction pressure (at atmospheric pressure up to 490 kPa = 71 psi) and is more economical than the Hquid-phase process because of the foUowing reasons owing to the low pressure operation, the consumption of electricity is largely reduced (—60%) dimethyl oxalate (DMO) formation and the methyl nitrite (MN) regeneration reaction are mn...
