Abstract

The invention discloses a precise temperature control system and method for micro reaction experiments. The system comprises a micro reactor and a temperature control system. The method comprises thesteps: step one, determining the temperature of a micro-reaction experiment; step two, setting the temperature of heat-preserving liquid; step three, leading reaction liquid; step four, collecting a temperature value of a micro-channel reactor; step five, determining whether the actual measurement temperature of a reaction material mixing plate is equal to the set temperature of the micro-reactionexperiment; step six, maintaining the heat-preserving liquid to be unchanged; step seven, determining whether the actually measured temperature of the reaction material mixing plate is greater than the set temperature of the micro-reaction experiment; step eight, determining whether the actually measured temperature of a reaction material input plate is greater than the set temperature of the micro-reaction experiment; step nine, determining whether the actually measured temperature of the reaction material input plate is lower than the set temperature of the micro-reaction experiment; step ten, reducing the temperature of the reaction material input plate; step eleven, reducing the temperature of the mixing material output plate; step twelve, increasing the temperature of the reaction material input plate; and step thirteen, increasing the temperature of the mixing material output plate. Therefore, the reaction temperature in the micro-reaction process can be controlled effectively and accurately.
