Hydroxylation
In chemistry, hydroxylation is a reaction to introduce one or more hydroxyl groups . Conversely, dehydroxylation is the splitting off of a hydroxyl group. The hydroxyl group consists of one hydrogen and one oxygen atom . In organic chemistry it is represented by the functional groups of alcohols and organic acids . Some inorganic compounds such as silica and aluminum hydroxide also contain hydroxyl groups.
Examples
- Catalytic partial oxidation of methane to methanol
- A cis - dihydroxylation , by addition of permanganate (MnO 4 - ) to a carbon -Kohlenstoff- double bond and subsequent hydrolysis are carried out using a dihydric alcohol ( diol ) is formed.
- Biochemical hydroxylations are made possible by enzymes such as hydroxylases , such as the hydroxylation of progesterone to corticosteroids .
- Dehydroxylation in the dealumination of zeolite Y by calcination to the ultra-stable form (USY)
