Monitoring reactions between hydrocarbons and water at hydrothermal conditions by Raman spectroscopic and microthermometric methods:The reactions between ethane and water at temperatures between 200 and 400℃
An experimental method has been developed for monitoring reactions between organic compounds and water at hydrothermal conditions by using Raman spectroscopic and microthermometric methods.As an example, the reactions between ethane and water were performed in fused silica capillary rubes at temperatures between 200 and 400℃. The Raman spectroscopic analyses of the reaction products indicate that both ethanol and acetic acid of about equal concentration were produced by the oxidation-hydration reactions of ethane. The degree of reaction after each heating was monitored by the change of density of liquid ethane,which can be accurately determined by measuring the temperature at which vapor ethane was homogenized to liquid ethane. The reaction could not be reversed by heating 1.96 m acetic acid solution in a silica capillary tube under hydrogen pressure imposed externally by the iron-magnetite buffer at 300℃ for 70 hours.
