    Abstract: An improvement in a process for converting an unsaturated, acyclic hydrocarbon to a carboxylic acid in which the unsaturated, acyclic hydrocarbon is reacted with oxygen containing a small amount of ozone at a low temperature to obtain an intermediate product in a first stage and the intermediate product is oxidized in a second stage with molecular oxygen at a higher temperature to obtain the desired carboxylic acid, which involves employing a solvent mixture comprising a major amount of a carboxylic acid solvent having a boiling point as high or higher than the highest boiling point of a carboxylic acid formed during the reaction and a minor amount of lower carboxylic acid solvent or a lower alcohol solvent, whereby fogging during the first stage of the process is reduced.

    Abstract: An improvement in a process for converting an unsaturated, acyclic hydrocarbon to an acid in which the unsaturated, acyclic hydrocarbon is reacted with oxygen containing a small amount of ozone at a low temperature to obtain an intermediate product in a first stage and the intermediate product is oxidized in a second stage with molecular oxygen at a higher temperature to obtain the desired carboxylic acid, which involves heating the intermediate product in the absence of additional oxygen prior to the second stage oxidation, whereby explosive hazards in the second stage are minimized.
