- methyl methacrylate was distilled in the same manner as in Example except that a tray was integrated and the folded portion 33 of the sabot beam was horizontal. . Open the interior one year after the start of distillation As a result, a polymer was formed on the upper surface of the folded portion 33, and the enlarged polymer was blocking a part of the through-hole of the tray serving as the gas-liquid flow path. In addition, a part of the polymer dropped on the tray below to block the through hole. For this reason, the efficiency of distillation was low, and it was less economical than the examples.
- the support beam has a shape and does not stay on the folded surface of the support beam for a long period of time, so the amount of polymerization inhibitor added is increased. Without forming a polymer. That is, the formation of a polymer can be prevented economically.
