APPLICATIONS
|
2-Piperidone, a keto-hydropyridine, is a 6-membered lactam structure compound
(delta-valerolactam). Lactam structure compounds including delta-valerolactam
are good organic solvents soluble in water. Cyclic amides and analogues including
N-alkyl lactams are biologically active nucleuses in pharmacologicals and
flavorings. Lactams are widely used in artificial fibre industry. They are
polymerizable and used as nylon precursors. They have excellent applications as
solvents and as intermediates for organic synthesis. They are used in the
aqueous carrier medium and amide penetrants in inks and water soluble
paints. 4-Piperidone, a cyclic amide with ketone at para position, and its N-alkyl
substituted derivatives are used in:
- Alkene formation at the position of former carbonyl group. Alkene bonds are
abundant in natural compounds
- Sulfur compound removals
- UV stabilizer
products
- Multicyclic hetero compounds and fused ring system
compounds
- Pharmaceutical synthesis including narcotic analgesics and
digestive system drugs
