一般描述

丙二醇是一种脂肪醇。它是一种丙二醇加成聚合物，在水中保存为H[OCH₃]_nOH，n代表了氧丙烯基的平均数。

应用

丙二醇（PPG）在化妆品中可用作降低粘稠度到的试剂，溶剂和芳香成分。 PPG是很好的膨胀试剂，可以用来合成大孔介孔材料。

Development of a Novel Lead that Targets M. tuberculosis Polyketide Synthase 13.

Anup Aggarwal et al.

Cell, 170(2), 249-259 (2017-07-04)

Widespread resistance to first-line TB drugs is a major problem that will likely only be resolved through the development of new drugs with novel mechanisms of action. We have used structure-guided methods to develop a lead molecule that targets the

A new aqueous biphasic system containing polypropylene glycol and a water-miscible ionic liquid.

Mohammed Taghi Zafarani-Moattar et al.

Biotechnology progress, 28(1), 146-156 (2011-09-29)

In this work, we proposed a novel aqueous biphasic system (ABS) composed of polypropylene glycol P400 (PPG P400) and hydrophilic ionic liquids (IL), 1-alkyl-3-methylimidazolium bromide (alkyl = ethyl or butyl), forming an upper polymer-rich phase and a lower IL-rich phase

There are various arguments and models connecting the characteristic length associated with the boson peak vibrations ξ to the length scale of dynamical heterogeneity L(het). ξ is usually defined as the ratio of the transverse sound velocity to the boson

Comparison of the surface tension of 5.25% sodium hypochlorite solution with three new sodium hypochlorite-based endodontic irrigants.
