A method of oxidizing hydrocarbons in liquid phase is provided. According to this method, a liquid-phase oxidation reaction of hydrocarbons is carried out by using an organic compound capable of chelating metals as auxiliary agent, represented by formula (II), in the presence of an oxygen-containing gas and a transition metal catalyst. Accordingly, the conversion degree of the hydrocarbon is increased, and the overall yields of products are improved while the selectivity of catalytic oxidation reaction is still high. 

Method for oxidizing hydrocarbons in liquid phase

A process for preparing a carboxylic acid by the carbonylation of an alcohol in a reaction medium is provided. The reaction medium includes a catalyst promoter having a metal species selected form the group consisting of group IIIA-IVA metals, group IB-VIIIB metals and lanthanides, together with a hydrohalic acid to prevent catalyst precipitation and to maintain high reaction rates in case of low water content.
