Pharmacology

Glutaral is a water-soluble oily liquid, C5H8O2, containing two aldehyde groups, used as a disinfectant and as a fixative for biological tissues.

How it is made

Glutardialdehyde is produced by gas-phase oxidation of cyclopentene or by Diels-Alder reaction of acrolein with methyl vinyl ether. The latter yields 3,4-dihydro-2-methoxy-2H-pyran, acidic hydrolysis of which leads to glutardialdehyde. ... In both cases the dialdehyde is recovered from the reaction mixture by multistage extraction with water.

The 1:1 Diels-Alder adduct of acrolein and vinyl alkyl ether is hydrolyzed yielding glutaraldehyde and alkanol.
