说明

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

聚乙二醇20000(PEG-20000)可作为扩孔剂，用于通过水热法制备介孔La₂O₃催化剂。PEG 20000可改善La₂O₃催化剂颗粒的碱度、结晶度、比表面积和分散性。改性后的催化剂对于碳酸二甲酯和甘油的酯交换反应的催化性能更强。
还可用作：

表面活性剂，用于各种方法合成纳米材料，控制纳米结构的大小和形态。
载体，用于制备零价铁-PEG纳米复合材料(Fe/PEG)，用于去除水性溶液中的Pb(II)。
