        Large amounts of MeOH (EtOH) are formed in the early stage of the slow oxidation of CH₄ (C₂H₆) at 50 atm.  Under similar conditions, the products obtained from EtOH, MeOH, AcH, and AcOH are such as to indicate a hydroxylation mechanism of combustion.  The oxidation of AcOH at reduced pressures (in silica) is predominantly homogeneous.  At 426°-486° at 200 mm. there is no marked induction period.  The products are CO, CO₂, CH₄, and H₂O with traces of AcOMe and acetone.
