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:
In enzymology, a 1,3-propanediol dehydrogenase (EC 1.1.1.202) is an enzyme that catalyzes the chemical reaction. propane-1,3-diol + NAD + 3-hydroxypropanal + NADH + H +. Thus, the two substrates of this enzyme are propane-1,3-diol and NAD +, whereas its 3 products are 3-hydroxypropanal, NADH, and H +.
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.
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.
The chemistry symbols of this structural formula are drawn using the path text method. The accuracy of this version of the structural formula has been verified as part of the Chemical Structure Validation project .
3-Nitrooxypropanol (abbreviated as 3-NOP or 3NOP) is a synthetic organic compound with the formula HOCH 2 CH 2 CH 2 ONO 2. [1] It is the mononitrate ester of 1,3-propanediol and acts as an enzyme inhibitor that specifically targets methyl coenzyme M reductase (MCR), the enzyme that catalyzes the final step of methanogenesis in microbes living in the digestive system of ruminants, such as cows ...
In enzymology, a lactaldehyde reductase (NADPH) (EC 1.1.1.55) is an enzyme that catalyzes the chemical reaction. propane-1,2-diol + NADP + L-lactaldehyde + NADPH + H +. Thus, the two substrates of this enzyme are 1,2-propanediol and NADP +, whereas its 3 products are L-lactaldehyde, NADPH, and H +.
