Abstract

Based on the idea of environmental protection and sustainable development, the developing of new procedure for the chemical conversion of plastics and related chemicals into value-added chemicals are always attractive. In this context, we designed a photocatalytic reaction that employs 4-alkyl-1,4-dihydropyridines (alkyl-DHP) and arylamines to degrade and transform formaldehyde polymers. This innovative process effectively degrades paraformaldehyde and polyoxymethylene plastic, yielding a series of amine products in satisfactory quantities. This new procedure unveils a new strategy for the chemical degradation of plastics.

光驱动金属自由基加成反应降解甲醛聚合物
基于环境保护和可持续发展的理念,开发塑料及相关化学品化学转化为增值化学品的新工艺一直具有吸引力。在这种情况下,我们设计了一个光催化反应,利用4-烷基-1,4-二氢吡啶(烷基- dhp)和芳胺来降解和转化甲醛聚合物。这种创新的工艺有效地降解多聚甲醛和聚甲醛塑料,产生一系列令人满意的胺产品。这个新程序揭示了塑料化学降解的新策略。

期刊介绍: Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
