A diol is a chemical compound containing two hydroxyl groups (−OH groups).[1] An aliphatic diol is also called a glycol.[2] This pairing of functional groups is pervasive, and many subcategories have been identified.
The most common industrial diol is ethylene glycol.

For academic research and pharmaceutical areas, vicinal diols are often produced from the oxidation of alkenes, usually with dilute acidic potassium permanganate.
:
1,3-Diols are often prepared industrially by aldol condensation of ketones with formaldehyde.
:
1,3-Diols can be prepared by hydration of α,β-unsaturated ketones and aldehydes.

Diole sind organische Verbindungen, die zwei alkoholische Hydroxygruppen (–OH) enthalten, also zweiwertige Alkohole (Dialkohole).
Ein Beispiel für ein einfaches, stabiles Diol ist Ethylenglycol (1,2-Ethandiol).

Diole
(Dialkohole). Gruppenbezeichnung für aliphatische und alicyclische Verbindungen, die zwei Hydroxy-Gruppen (vergleiche Di... und ...ol) im Molekül enthalten; Beispiel: Ethylenglycol, Butandiole, 2,2-Dimethylpropan-1,3-diol, Decan-1,10-diol, Cyclohexan-1,4-dimethanol; aromatische Dihydroxy-Verbindungen (Phenole) vom Typ des Brenzcatechins bezeichnet man als Hydrochinone (vergleiche Hydrochinon) und die durch Hydroxylierung herstellbaren Diole mit vicinalen (benachbarten) Hydroxy-Gruppen (1,2-Diole) als Glycole bzw. Pinacole.
Technisch sind die Diole als Komponenten der Polyurethane und Polyester und als Zwischenprodukte für Pharma- und Pestizidwirkstoffe, Lackrohstoffe etc. von erheblicher Bedeutung.

For this reason, a 2nd process is also normally performed, extracting diol out of a reaction system under reduced pressure. In order to extract this diol efficiently, it is preferable to extract steam outside a reaction system as it is, without using a rectifying tower unlike 1st process.
