Propylene glycol - Wikipedia
Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid. It is almost odorless and has a faintly sweet taste. Its chemical formula is CH 3 CH (OH)CH 2 OH. As it contains two alcohol groups, it is classified as a diol. An aliphatic diol may also be called a glycol.
Propylene glycol | Description, Formula, Production, & Uses
2024年10月25日 · Propylene glycol can be made in commercial production by the direct hydrolysis of propylene oxide with water. Alternatively, the chlorohydrin process or peroxidation can be used; each of these processes starts with the monomer propylene (also called propene, a three- carbon chain that contains one carbon-to-carbon double bond).
Propylene Glycol: Uses in Food, Cosmetics, and More - Verywell …
2023年7月2日 · Propylene glycol can be created in two different ways. It is primarily made by treating propylene oxide—a chemical produced from refining petroleum—with water. Propylene glycol can also be obtained from glycerol, a major byproduct of biodiesel production.
MPG: Production - Propylene Glycol Sector Group
In the traditional production process propylene glycol is made from propylene oxide reacted with water. The resulting material is a mixture of mono-, di- and tri-propylene glycols that are then distilled to purify to the different grades of propylene glycol.
Propylene Glycol: Production, Reactions And Uses
2024年7月21日 · Production of Propylene glycol by Hydrolysis of Propylene Oxide. The dominant process for industrial production of 1,2-propanediol involves the direct hydrolysis of propylene oxide in the presence of water.
Insights on production mechanism and industrial applications of ...
Renewable propylene glycol can be produced from catalytic hydrogenolysis of glycerol. This study reviews different catalyst for glycerol hydrogenolysis, the reaction mechanism, and process challenges. Additionally, previous studies related to the economic and environmental assessment of propylene glycol production are presented in detail.
Kicking the Oil Habit: Making Propylene Glycol from Plants
Pacific Northwest National Laboratory (PNNL) developed the first-ever catalytic process that converts plant-based raw materials to produce this valuable additive. Now, instead of relying on oil, industry has an alternative way to make propylene glycol that is environmentally friendly, cost-competitive, and commercially viable.
Propylene Glycol | C3H8O2 | CID 1030 - PubChem
Propylene glycol is a synthetic liquid substance that absorbs water. Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze when leakage might lead to contact with food.
Propylene glycol - Sciencemadness Wiki
2023年11月18日 · Propylene glycol, also called propane-1,2-diol or α-propylene glycol to differentiate it from its propane-1,3-diol isomer, is an organic compound with the chemical formula C3H8O2. Propylene glycol is metabolized in the human body to pyruvic acid. Acid catalyzed dehydration of propylene glycol will give dimethyl dioxane.
Propylene glycol - New World Encyclopedia
Each molecule of propylene glycol consists of a chain of three carbon atoms (as in propane), with two hydroxyl (or "alcohol," OH) functional groups attached to two adjacent carbon atoms. It is therefore classified as a "diol." The chemical formula may be …
