Abstract: The evaluation of pressure effects is obtained by performing the hydrolysis of methyl octadecanonate as a model reaction catalyzed by seven different samp les of immature source rock that had first been extracted with organic solvents. The results show that p ressure plays an important role in the reaction and the pressure effects are not negligible. The pressure effects are different among the seven immature source rock. As a conquence, an enhanced or lowered ratios of hydrolysis takes place as a result of the pressure effects. The reasons that lead to such a result are discussed. It is suggested that the pressure effects observed is a complex of the promotion and restraint caused by pressure.
