Two automated reaction calorimetry systems were built and tested. The first made use of a quartz thermometer probe as the temperature measuring element. The second was constructed using a thermister which was part of a Wheatstone bridge. The off-balance voltage from the bridge was measured using the 6 1/2 digit digital voltmeter, and transferred to the microprocessor. The one disadvantage of the first system is the relatively large size of the quartz sensor. The calorimeter systems were used to measure: the enthalpies of hydrolysis of ketals, acetal, orthoesters, enthalpies of hydration of alkenes; enthalpies of formation of small ring hydrocarbons.
