Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. Approximately 950,000 tons per year are produced in the United States and Europe; 350,000 tons of glycerol were produced per year in the U.S. alone ...
According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]
HOCH 2 CH 2 OH + n(CH 2 CH 2 O) → HO(CH 2 CH 2 O) n+1 H. Depending on the catalyst type, the mechanism of polymerization can be cationic or anionic. The anionic mechanism is preferable because it allows one to obtain PEG with a low polydispersity. Polymerization of ethylene oxide is an exothermic process.
Sulfuric acid contains two hydroxy groups.. Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1).

You can use many different starting materials to produce syn- or anti-1,3-diols. [10] The resulting carbonyl is reduced using the Cannizzaro reaction or by catalytic hydrogenation: RC(O)CH 3 + CH 2 O → RC(O)CH 2 CH 2 OH RC(O)CH 2 CH 2 OH + H 2 → RCH(OH)CH 2 CH 2 OH. 2,2-Disubstituted propane-1,3-diols are prepared in this way.
Reuterin (3-hydroxypropionaldehyde) is the organic compound with the formula HOCH 2 CH 2 CHO. It is a bifunctional molecule, containing both a hydroxy and aldehyde functional groups. The name reuterin is derived from Lactobacillus reuteri, which produces the compound biosynthetically from glycerol as a broad-spectrum antibiotic (bacteriocin). [1]
