Abstract

-Methyl-2-pyrrolidone is a toxic dipolar aprotic solvent widely used in the synthesis of polyurethane dispersions (PUD). Since legislation strongly restricts this substance, green alternatives are essential. Dihydrolevoglucosenone and gamma valerolactone demonstrate comparable performance to that of NMP as cosolvent in the synthesis and the film forming process of PUD.

摘要

N-甲基-2-吡咯烷酮是一种有毒的偶极非质子溶剂，广泛用于聚氨酯分散体（PUD）的合成。由于法规对该物质有严格限制，绿色替代品至关重要。二氢左旋葡萄糖酮和γ-戊内酯在PUD的合成和成膜过程中作为助溶剂表现出与NMP相当的性能。
