Abstract

An investigation was carried out to improve the production of acetic acid by an alkaline two-step process, in which the first step is to accelerate the formation of lactic acid in a hydrothermal reaction with the addition of alkali, and the second step is further convert the lactic acid produced in the first step to acetic acid by oxidation with newly added oxygen. Results showed that the addition of alkali promoted selectively the formation of lactic acid from glucose at a hydrothermal condition. Acetic acid yield in the alkaline two-step process greatly increased in comparison to that without the addition of any alkali. In the alkaline two-step process, the highest acetic acid yield arrived at 27 % on the carbon base under the conditions of reaction temperature of 300 °C, reaction time of 1 min, and Ca(OH)2 concentration of 0.32 M in the first step, and reaction temperature of 300 °C, reaction time of 3 min, and oxygen supply of 70 % in the second step.
