Heat-exchanging method for easily polymerizable compound

摘要

The present invention provides a heat-exchanging method for an easily polymerizable compound which method effectively prevents polymerization in a heat exchanger to enable a long-term stable heat exchange when an easily polymerizable liquid compound (for example, acrylate ester) or an easily polymerizable compound-containing liquid (for example, aqueous acrylic acid solution) is heat-exchanged. A vertical spiral type heat exchanger with a fluid path space of not less than 6 mm is used as a heat exchanger to carry out the heat exchange under conditions where the average liquid flow rate is not less than 0.2 m/sec and where the liquid residence time is not more than 100 seconds.
