The present invention relates to a process for the preparation of C. sub. 5 -C. sub. 8 aliphatic dibasic acids through oxidation of corresponding saturated cycloaliphatic hydrocarbons by (1) reacting, at a cycloaliphatic hydrocarbon conversion level of between about 7% and about 30%, (a) at least one saturated cycloaliphatic hydrocarbon having from 5 to 8 ring carbon atoms in the liquid phase and (b) an excess of oxygen gas or an oxygen-containing gas mixture in the presence of (c) less than 1. 5 moles of a solvent per mole of cycloaliphatic hydrocarbon (a), wherein said solvent comprises an organic acid containing only primary and/or secondary hydrogen atoms and (d) at least about 0. 002 mole per 1000 grams of reaction mixture of a polyvalent heavy metal catalyst; and (2) isolating the C. sub. 5 -C. sub. 8 aliphatic dibasic acid.

A polyhydric compound is produced by catalytically disproportionating a precursor which is a lower carboxylate ester of said compound containing at least one lower carboxylate group and at least one free hydroxyl group. Most preferably the invention relates to the production of a diol by the catalytic disproportionation of a lower carboxylate diester of the diol.

A process for the industrial production of ethylene oxide and an aromatic acid by reacting oxygen with ethylene and a methyl aromatic compound in the liquid phase. Oxygen and ethylene are passed into a liquid mono or poly methyl aromatic compound and reacted therein to produce ethylene oxide and methyl aromatic oxidates. The aromatic oxidates are then further oxidized to produce aromatic acids. When the methyl aromatic compound used is toluene the acid produced is benzoic acid, from p-xylene, terephthalic acid is produced; from m-xylene isophthalic acid is produced; and from pseudocumene (1, 2, 4 trimethyl benzene) trimellitic acid is produced.

Glycol esters of an olefin are prepared by contacting an olefin and a molecular oxygen containing gas in a carboxylic acid medium in the presence of a catalyst. Selectivities to the desired glycol esters are improved by treating the viscous residue and the precursor light components separated from the oxidation effluent by contacting them with water. In a preferred embodiment both residue and precursor light components streams are fed to the same zone wherein they are converted to additional glycol.

Ethylene glycol is prepared by reacting methanol and an organic peroxide of the formula R--O--O--R. sub. 1, wherein R and R. sub. 1 are each an alkyl or aralkyl group having 3 to 12 carbon atoms, in the presence of a minor amount of a basic material. Preferably, formaldehyde is present as a reactant in the presence of water. The presence of the basic material reduces the hydrogen ions which are formed and thus reduces the amount of methylal produced.

Ethylene glycol is prepared by reacting methanol, formaldehyde and from greater than 6 to about 25 weight percent of an organic peroxide in the presence of about 0. 5 to about 35 weight percent of water based on the feed composition, the amount of water within said range being correlated with the peroxide content. The organic peroxide has the formula R--O--O--R. sup. 1 wherein R and R. sup. 1 are each an alkyl or aralkyl group having 3 to 12 carbon atoms.
