詳細
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.
アプリケーション
Polyethylene glycol 20000 (PEG-20000) can be used as a pore-expanding agent to prepare mesoporous La2O3 catalyst via hydrothermal process. The effect of PEG 20000 on La2O3 catalyst particles, results in increased alkalinity, crystallinity, specific surface area, and dispersion. These modifications of the catalyst improve the catalytic performance in the transesterification of dimethyl carbonate with glycerol.
It can also be used as:
It can also be used as:
- A surfactant in the synthesis of nanomaterials by various methods to control the size and morphology of nanostructure.
- A support to prepare zero-valent iron-PEG nanocomposite material (Fe/PEG) applicable in the removal of Pb(II) from aqueous solutions.
