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 d
N-Methyl-2-pyrrolidone: 872-50-4 CH 3 CH 2 CH 2 OH: 1-Propanol: 71-23-8 CH 2 (CH 2 OH) 2: 1,3-Propanediol: 504-63-2 HOCH 2 CH 2 CH 2 CH 2 CH 2 OH: 1,5-Pentanediol: 111-29-5 (CH 3) 2 CHOH: 2-Propanol: 67-63-0 CH 3 CH 2 COOH: propanoic acid: 79-09-4 HOCH 2 CHOHCH 3: propylene glycol: 57-55-6 C 5 H 5 N: pyridine: 110-86-1 C 4 H 8 O 2 S: sulfolane ...
Examples include ethane-1,2-diol or ethylene glycol HO−(CH 2) 2 −OH, a common ingredient of antifreeze products. Another example is propane-1,2-diol, or alpha propylene glycol, HO−CH 2 −CH(OH)−CH 3, used in the food and medicine industry, as well as a relatively non-poisonous antifreeze product.
Propylene glycol dinitrate (PGDN, 1,2-propylene glycol dinitrate, or 1,2-propanediol dinitrate) is an organic chemical, an ester of nitric acid and propylene glycol. It is structurally similar to nitroglycerin , except that it has one fewer nitrate group.
1,3-Propanediol is mainly produced by the hydration of acrolein. An alternative route involves the hydroformylation of ethylene oxide to form 3-hydroxypropionaldehyde. The aldehyde is subsequently hydrogenated to give 1,3-propanediol. Biotechnological routes are also known. [2] Two other routes involve bioprocessing by certain micro-organisms:
logX m = ƒ 1 logX 1 + ƒ 2 logX 2. Where X m is the mole fraction solubility of the solute, X 1 and X 2 denote the mole fraction solubility in neat cosolvent and water. While this model is only correlative in nature, further analysis allows for the creation of a predictive element. Simplifying the above equation to: logX m = logX 2 + σ • ƒ 1
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. [3] [4] [5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency [6] while the composition must be disclosed if the regulator demands it.
