LKB8700 precision titration calorimeter has been improved and equipped with a microcomputer in our laboratory, which can be operated conveniently and automatically. Error analysis of titration calorimetry suggests that experiments can be performed accurately.
The improved and on-line calorimeter is especially suitable for investigation of oil-water-surfactant systems which are directly related to the enhanced oil recovery. The calorimetric system has been checked by means of measuring heat of dilution and heat of reaction of Tris (Trihydroxymethylaminomethane) with HCl. The result (-47.46 J·mol~(-1)) obtained agrees well with the literature's value.
