The Reaction of Hydrogen Atoms with Some Oxygen-Containing Organic Compounds

Abstract
The reactions of atomic hydrogen, produced by a discharge, with methyl ether, acetaldehyde, and ethylene oxide have been investigated. The main products of the reactions are: from methyl etherCH4,CO,H2O,C2H6, andHCHO;from acetaldehydeCH4,CO, andC2H6;from ethylene oxideCH4,CO, andCH3CHO. The mechanisms of the reactions are discussed in detail and it is concluded that the primary reactions are: H+CH3OCH3H2+CH3OCH2E=7.0 kcal.H+CH3CHO →H2+CH3COE≤6.0 kcal.H+(CH2)2O  →H2+C2H3OE=8.5 kcal., and that the main secondary reactions in all cases are of the atomic cracking type: H+CH3OCH2CH3+CH3O,H+CH3CO   →CH3+CHOor    →CH4+CO,H+C2H3O   →CH3CHOor    →CH4+CO.
