1,3-Propane sultone is the organosulfur compound with the formula (CH 2) 3 SO 3. It is a cyclic sulfonate ester, a class of compounds called sultones . [ 2 ] [ 3 ] It is a readily melting colorless solid.
1,3-Propanediol is the organic compound with the formula CH 2 (CH 2 OH) 2. This 3-carbon diol is a colorless viscous liquid that is miscible with water. Products.
Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters , paints , lubricants , and plasticizers . When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water.
The three main types of chemicals in the fluid at this stage of the separation are water, BioPDO, and impurities such as glycerol, sugars, and proteins. Of the three chemicals water has the lowest boiling point (see the water, 1,3-propanediol, and glycerol articles for boiling point information), so it is removed as distillate in the first column.
2,2-Disubstituted propane-1,3-diols are prepared in this way. Examples include 2-methyl-2-propyl-1,3-propanediol and neopentyl glycol. 1,3-Diols can be prepared by hydration of α,β-unsaturated ketones and aldehydes. The resulting keto-alcohol is hydrogenated. Another route involves the hydroformylation of epoxides followed by hydrogenation of ...
Glycerol-1,2-carbonate is formally the cyclic ester of carbonic acid with ... or 3-chloro-1,2-propanediol or ... with anhydrous zinc sulfate as a heterogeneous ...
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. [7]
Propanediol may refer to any of four isomeric organic chemical compounds: Non-geminal diols (glycols) 1,2-Propanediol, a.k.a. propylene glycol, a vicinal diol;
