Propylene Glycol vs. Ethylene Glycol | Dynalene, Inc.
To illustrate this, compare the properties of 50 volume % propylene glycol versus ethylene glycol. 50% propylene glycol has a freezing pointof -31°F, where 50% ethylene glycol freezes at -36°F. The viscosity of that propylene glycol solution is 96 centipoise at -10°F, and the ethylene glycol will be 27 centipoise at the same temperature.
Ethylene glycol is a clear, odorless, slightly viscous liquid with a sweet taste. It is combustible and has a low vapor pressure. Ethylene glycol is a very useful industrial compound because of its low freezing point and high boiling point. It is widely available as automotive antifreeze; in that application, it is often mixed with a yellow-green fluorescent.
Photo-thermal conversion characteristics of carbon black-ethylene ...
Direct absorption solar collector (DASC) is a promising method of harvesting solar energy. Present work considers carbon black-ethylene glycol (CB-EG) based nanofluids as the working fluids for DASC applications. Nanofluids were synthesized by the two-step method.
Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C) . Ethylene glycol is also commonly used in heating …
Prediction of thermal conductivity of ethylene glycol–water solutions ...
The results indicated that nanobrine with ethylene glycol of volume fractions ranging from 10% to 90% has better thermal properties than aqueous solution of ethylene glycol. The objective of this study is to develop an ANN model to predict the thermal conductivity of ethylene glycol–water solutions based on experimentally …

ChemInform Abstract: Ethylene Glycol: Properties, Synthesis, and ...
Ethylene glycol (EG) is an important organic compound and chemical intermediate used in a large number of industrial processes (e.g. energy, plastics, automobiles, and chemicals).
Ethylene glycol-based solar-thermal fluids dispersed with reduced graphene …
Direct absorption solar collectors, which use optical nanofluids to volumetrically absorb and convert sunlight into heat, have emerged as promising devices to harvest solar-thermal energy for many heat-related applications. Nanofluids, however, generally suffer from aggregation issues and the widely investigated wa
Towards the sustainable synthesis of ethylene glycol
The electrochemical synthesis of high-value chemicals is still far from industrial application, mostly due to the lack of stable and efficient catalysts. ... Ethylene glycol is a valuable chemical ...
