AUTOCATALYTIC HYDROLYSIS AND AUTOOXIDATION OF CRUDE PALM OIL UNDER VARIOUS CONSTANT HUMIDITIES

CHOOI Siew Yuen* ; KOH Heng Fui** ; WREN, W G+

ABSTRACT

The kinetics of autocatalytic hydrolysis of crude palm oil was studied at moisture below solubility using the isopiestic methods, in which the oil was exposed to a volume of sulphuric acid at a certain concentration in a closed system and stored at 55C. Different humidities were created by using different concentrations of sulphuric acid, thereby effecting different activities of water in the oil
