Mechanisms of hydrogen formation in the radiolysis of gaseous CH3OH and CD3OH

Infrared Study on β-Radiolysis in Methanol-T2O System

“…From mass balance EG and H 2 CO are expected to be formed seldom. Hence the present result differs quite markedly from those reported [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. We can define the G value for methanol as follows: where kß and [T] 0 are the rate constant of the β decay, 1 /6460 (day" 1 ), and the initial pressure of tritium, 5 Torr, respectively.…”

“…3. These findings suggest that CH 4 is also formed from CO, HC0 2 Me and so on in addition to the formation from a Me + ion [1 4,6,8,9,13,25] and a Me radical [4,10].…”

“…The main products are ethylene glycol (EG) and H 2 CO, with small amounts of CO and CH 4 , which is kinetically analyzed on the basis of abundance in both mass spectroscopy and/or photolysis. A similar result has also been found for high energy electron impact [16][17][18].…”

“…2, where their pressures in Torr were 3.0,3.5 and 9.1, respectively. The determination of MeOH, CO, CH 4 and HC0 2 Me was carried out by use of the bands at 3672 cm" 1 for MeOH, 2143 cm"' for CO, 1306 cm" 1 for CH 4 …”
