Abstract: What is described is a process for producing water-absorbing resins, in which a) acrylic acid is prepared at an acrylic acid production site, b) the acrylic acid prepared is dissolved in water at the acrylic acid production site to obtain an aqueous acrylic acid solution, c) the aqueous acrylic acid solution is fed into a pipeline at the acrylic acid production site and passed through the pipeline to an acrylic acid processing site and d) the aqueous acrylic acid solution is subjected to a free-radical polymerization at the acrylic acid processing site. The process ensures safe transport of the highly reactive acrylic acid. Endangerment as a result of premature polymerization, as in the case of glacial acrylic acid, is ruled out, since the acrylic acid is “diluted” by the aqueous solvent and the specific heat capacity and the evaporation enthalpy of the water limit the maximum temperature rise. The amount of polymerization inhibitors used be reduced or it is possible to entirely dispense with polymerization inhibitors. Temperature control of vessels and pipelines within which the aqueous acrylic acid solution is conducted can be dispensed with because the solidification point of the aqueous acrylic acid solution is lower than that of anhydrous acrylic acid.

Abstract translation: 描述的是一种生产吸水树脂的方法，其中a）在丙烯酸生产部位制备丙烯酸，b）将制备的丙烯酸溶解在丙烯酸生产部位的水中，得到含水丙烯酸 溶液，c）丙烯酸水溶液进料到丙烯酸生产现场的管道中，通过管道进入丙烯酸加工现场，并且d）丙烯酸水溶液在丙烯酸处理下进行自由基聚合 酸加工现场。 该方法确保高反应性丙烯酸的安全运输。 由于丙烯酸被水性溶剂“稀释”，所以比例热容量和水的蒸发焓限制了最大温度上升，因此排除了由于过早聚合而导致的过早聚合的结果，如在丙烯酸的情况下 。 使用的聚合抑制剂的量减少，或者可以完全省去聚合抑制剂。 由于丙烯酸水溶液的固化点低于无水丙烯酸的固化点，所以可以省去进行丙烯酸水溶液的容器和管道的温度控制。
