摘要:

丙烯酸是化工生产中的一种重要单体,以其为原料所生产的黏合剂、涂料和高吸水性树脂等材料可被广泛应用于日常生活和工业生产等领域。丙烯酸分子具有碳碳双键和吸电子基团,其化学性质较为活泼,在合成、提纯和储存工段易发生自聚,会对生产过程中的安全和产品质量产生不利影响。因此,防止丙烯酸单体自聚成为了其生产过程中的关键一环。介绍了丙烯酸的自聚机理,阐述了引发其自聚的条件因素,并总结了相应的防聚措施,以期为丙烯酸生产系统的稳定运行提供技术参考。

Abstract:

Adhesives, coatings and superabsorbent resins produced from acrylic acid can be widely used in daily life and industrial production. Acrylic acid possesses carbon-carbon double bonds and electron-absorbing groups, and its chemical properties are relatively active, and self-polymerization is easy to occur in the synthesis, purification and storage sections, which will adversely affect the process safety and product quality. Therefore, the prevention of self-polymerization of acrylic monomers has become a key part of its production process. It introduces the self-polymerization mechanism of acrylic acid, describes the conditions that cause its self-polymerization in detail, and summarizes the corresponding anti-polymerization measures, in order to provide technical reference for the stable operation of acrylic acid production system.
