extremely high ionicliquid concentrations, up to molar ranges in some cases. The biodegradability of these ionicliquids was assessed, and new biotechnological applications for them are proposed, e.g. as solvents for biopolymers. This study leads to the better understanding of the anion influence on the ionicliquid toxicity, but its core is the recognition that conscious design of ionicliquids can be used
一种新药的合成,表征和毒理学评估 团体介绍了环保的离子液体。着眼于阴离子的毒性作用,通过结合良性胆碱阳离子[NMe 3(CH 2 CH 2 OH)] +与线性范围的离子液体来设计离子液体。链烷酸酯阴离子([C n H 2 n +1 CO 2 ] -,n = 1-9),以及两个结构异构体(n = 3或4)。使用丝状真菌作为模型真核生物评估了这些离子液体的毒性。令人惊讶的是,大多数被测物种都表现出活跃生长在含有极高离子液体浓度的介质中,在某些情况下可达摩尔范围。这些离子液体的生物降解性进行了评估,并为他们新的生物技术应用提出,如作为溶剂 为了 生物聚合物。这项研究可以使人们更好地了解阴离子对离子液体毒性的影响,但其核心是认识到,离子液体的有意识设计可用于提供真正的生物相容性盐,而不会不利地影响其最引人注目的性能之一。杰出的溶剂 能力。
A green and sustainable approach to utilize bio-ionic liquids for the selective precipitation of high purity agarose from an agarophyte extract
Preferential precipitation of agarose was observed upon addition of choline based bio-ionic liquids in the Gracilaria dura seaweed extract. Choline laurate was found to be the most effective for the work.

A composition for the immediate stopping of a free-radical polymerization comprises a) an inhibitor for the free-radical polymerization selected from among phenothiazines, b) an aprotic solvent and c) an ionic liquid. It serves to stabilize free-radically polymerizable monomers against free-radical polymerization. For the immediate stopping of free-radical polymerizations, the composition is added to a free-radically polymerizing system.
