  The polymerization of vinyl aromatic compounds during the distillation of the vinyl aromatic compounds is inhibited by adding to the vinyl aromatic compound, e.g., styrene, undergoing distillation the reaction product of nitrous acid and a phenylene diamine, e.g. N-nitroso-N, N'-di-3-pentyl-p-phenylenediamine.

  在乙烯基芳香族化合物蒸馏过程中，通过向乙烯基芳香族化合物（如苯乙烯）中加入亚硝酸和苯二胺（如 N-亚硝基-N，N'-二-3-戊基-苯二胺）的反应产物，可抑制乙烯基芳香族化合物的聚合。

  The present invention is directed to an apparatus and method for the distillation of a readily polymerizable vinyl aromatic compound employing a polymerization inhibitor. The vinyl aromatic compound is subjected to distillation in at least one fractionation column having at least one reboiler for maintaining the bottoms of said column at a proper temperature. The reboiler comprises a heating section and a vapor phase section. The bottoms fraction from the fractionation column is cycled to the reboiler and subjected to heat to vaporize at least a portion of the bottoms fraction to form a vapor phase in the vapor section. A slip stream of the bottoms fraction is introduced to the vapor phase section of the reboiler. The slipstream contains polymerization inhibitor that had been added to the process at the fractionation column. The invention reduces fouling at the reboilers. The slipstream is optionally introduced to the reboiler using one or more spray nozzles. The polymerization inhibitor is added to the fractionation column in sufficient amounts to maintain a concentration of at least 400 parts per million by weight in the bottoms fraction.

  本发明涉及一种使用聚合抑制剂蒸馏易聚合乙烯基芳香化合物的装置和方法。乙烯基芳香族化合物在至少一个分馏塔中进行蒸馏，该分馏塔至少有一个再沸器，用于将所述塔底保持在适当的温度。再沸器包括一个加热段和一个气相段。来自分馏塔的底部馏分循环进入再沸器，通过加热使底部馏分的至少一部分汽化，在汽相段形成汽相。底物馏分的滑流被引入再沸器的气相段。滑流中含有在分馏塔工艺中添加的聚合抑制剂。本发明可减少再沸器的堵塞。可选择使用一个或多个喷嘴将滑流引入再沸器。在分馏塔中加入足够量的聚合抑制剂，以保持底部馏分中的浓度至少为百万分之 400（按重量计）。
