Abstract
A thermal method for studying chemical responses, such as catalyzed polymerization reactions that includes the following three steps. The first step is to flow a chemical substance through a conduit, the conduit being in thermal communication with an electrical conductor, the electrical conductor being co-linear with the conduit, the electrical resistance of the electrical conductor being a function of the temperature of the electrical conductor. A length of stainless steel tubing can be used as both the conduit and the conductor. The second step is to flow electricity through the electrical conductor during the first step. The third step is to measure the electrical resistance of the electrical conductor during the second step to determine any change in the temperature of the conduit caused by a response of the chemical substance. An apparatus for studying chemical reactions that includes: a first conduit, the first conduit being an electrical conductor, the first conduit having a first end and a second end, the electrical resistance of the first conduit being a function of the temperature of the first conduit; a source of electricity, the source of electricity in electrical commu…
