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.
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 ...
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.
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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
This compound may be prepared from 1,3-propanediol and ethyl chloroformate (a phosgene substitute), or from oxetane and carbon dioxide with an appropriate catalyst: [2] HOC 3 H 6 OH + ClCO 2 C 2 H 5 → C 3 H 6 O 2 CO + C 2 H 5 OH + HCl C 3 H 6 O + CO 2 → C 3 H 6 O 2 CO. This cyclic carbonate undergoes ring-opening polymerization to give poly ...
Structure of (C 3 H 6 S 2) 2, the oxidized "dimer" of 1,3-propanedithiol. [4] 1,3-Propanedithiol is used in the synthesis of tiapamil. 1,3-Propanedithiol reacts with metal ions to form dithiolates. Illustrative is the synthesis of the derivative diiron propanedithiolate hexacarbonyl upon reaction with triiron dodecacarbonyl: [5] Fe 3 (CO) 12 ...
