一种防止硝化产物精馏塔爆炸的方法
摘要：
本发明涉及一种防止硝化产物精馏塔爆炸的方法，向精馏塔釜中加入稳定剂，所述稳定剂由膨润土、聚磷酸和丙烯酸-丙烯酸酯共聚物均匀混合组成，然后按照1％-5％(质量百分比)的比例加入精馏塔釜中。优选地，所述稳定剂由10-80％(质量百分比)的膨润土，15-85％(质量百分比)的聚磷酸，5-75％(质量百分比)的丙烯酸-丙烯酸酯共聚物组成。采用本发明所述的方法，可以防止危险组分的生成和积累，有效地防止塔釜爆炸，确保塔釜稳定地运行。
摘要（英）：

The invention relates to a method for preventing a nitration product rectifying tower from exploding. The method comprises the following steps of: adding a stabilizing agent into a rectifying tower kettle, wherein the stabilizing agent is prepared by mixing bentonite, polyphosphoric acid and an acrylic acid-acrylic ester copolymer; and adding 1-5 percent by mass of stabilizing agent into the rectifying tower kettle. Preferably, the stabilizing agent is prepared by mixing 10-80 percent by mass of bentonite, 15-85 percent by mass of polyphosphoric acid and 5-75 percent by mass of acrylic acid-acrylic ester copolymer. Due to the adoption of the method, the generation and the accumulation of dangerous components can be prevented, the explosion of the tower kettle is effectively prevented, andthe stable running of the tower kettle is ensured.
