Purification method and apparatus for easily polymerizable substance-containing material |
| abstract |
(57) [Summary] [PROBLEMS] To prevent polymerization of easily polymerizable substance-containing substances, The present invention relates to a method and an apparatus for purifying an easily polymerizable substance. SOLUTION: When purifying and separating an easily polymerizable substance-containing substance using a distillation column having a heat exchanger, the linear velocity of steam in a connecting pipe between the distillation column and the heat exchanger is set to 5 / sec. m and a retention time of 3 seconds or less, and a method for purifying an easily polymerizable substance-containing substance, and an apparatus therefor. |
