    摘要: An Alpha , omega -glycol, a primary alcohol or an aliphatic compound having one or two secondary alcohol groups is dissolved in a solvent. The resulting solution is heated to 10* - 70*C and brought into contact with an ozone-containing gas. Then, the solution is elevated to 70* - 110*C and brought into contact with an oxygen-containing gas. By thus oxidizing the starting material, there is formed in the solution a dibasic acid or a fatty acid; the former acid occurs where the starting material being used is an Alpha , omega -glycol and the latter acid occurs where it is either a primary alcohol or an aliphatic compound having one or two secondary alcohol groups. The dibasic acid or fatty acid thus formed within the solution can be isolated by removing the solvent from the solution.
