With the advent of the green chemistry concept novel, innocuous, biodegradable solvents require introduction in industrial processes. N,N‐dimethyl lactamide (AGNIQUE AMD 3L) represents a bio‐based, biodegradable, label‐free polar, protic solvent. In this article, AGNIQUE AMD 3L is introduced as novel solvent for preparation of polyethersulfone (PESU) nonsolvent‐induced phase separation ultrafiltration membranes using polyvinylpyrrolidone or poly(ethylene oxide) as second dope additives. Analysis of Hansen solubility parameters indicates good solvent–polymer interactions for polymer dope compositions required for PESU membrane manufacturing. Depending on the process conditions, PESU ultrafiltration membranes with hydraulic permeability values up to 610 kg m⁻² × bar × h and molecular weight cutoff value of 20 kDa were obtained. Scanning electron microscope of membrane cross sections reveals perfect defect‐free, asymmetric morphologies. As a result, AGNIQUE AMD 3L provides a new alternative as replacement for polar, aprotic solvents employed in membrane manufacturing so far. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

AGNIQUE AMD 3L作为绿色溶剂，用于制备聚醚砜超滤膜

随着绿色化学概念的出现，要求在工业过程中引入无害的，可生物降解的溶剂。N，N-二甲基乳酰胺（AGNIQUE AMD 3L）代表一种基于生物的，可生物降解的，无标签的极性质子溶剂。本文介绍了AGNIQUE AMD 3L作为新型溶剂，该方法使用聚乙烯吡咯烷酮或聚环氧乙烷作为第二种涂料添加剂来制备聚醚砜（PESU）非溶剂诱导的相分离超滤膜。Hansen溶解度参数的分析表明，PESU膜制造所需的聚合物涂料组合物具有良好的溶剂-聚合物相互作用。根据工艺条件，PESU超滤膜的水力渗透率值可达610 kg m ^-2×bar×h，分子量截留值为20kDa。膜截面的扫描电子显微镜显示出完美的无缺陷，不对称形态。结果，AGNIQUE AMD 3L提供了一种新的替代品，以替代迄今为止在膜制造中使用的极性，非质子溶剂。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学 2020，137，48419。
