Propylene glycol boiling temp
Forty-five percent of propylene glycol produced is used as a chemical feedstock for the production of unsaturated polyester resins. In this regard, propylene glycol reacts with a mixture of unsaturated maleic anhydride and isophthalic acid to give a copolymer. This partially unsaturated polymer undergoes further crosslinking to yield thermoset plastics. Related to this application, propylene gl… Webb1 juli 2024 · Water is nature’s heat transfer fluid, a liquid used since the dawn of time to heat and cool. It freezes at 32°F (0°C) and boils at 212°F (100°C). To extend the liquid range, other chemicals are added such as ethylene and propylene glycol. Ethylene glycol and propylene glycol are two chemical compounds used as low temperature heat ...
