Application
环丁砜是一种极性非质子溶剂,可用于纤维素的完全热解,而无需任何聚合或碳化副反应。环丁砜与均三甲苯结合,可用作从 L-天冬氨酸合成聚(琥珀酰亚胺)(PSI)的溶剂。它还可以用作合成氯封端的聚醚砜低聚物的溶剂,这是一种用于尼龙 6-聚醚砜(PES)-尼龙 6 嵌段共聚物合成的聚合物活化剂。

Sulfolane is an industrial solvent and emerging organic contaminant affecting groundwater around the world, but little is known about microbes capable of biodegrading sulfolane or the pathways involved. We combined DNA-based stable isotope probing (SIP) with genome-resolved metagenomics to identify
Polymer micelle-like aggregates of novel amphiphilic biodegradable poly (asparagine) grafted with poly (caprolactone).
