1,3-cyclohexanedione is a chemical compound from the group of cyclohexane derivatives and ketones .
Extraction and presentation
1,3-Cyclohexanedione can be obtained by reducing resorcinol with hydrogen in sodium hydroxide solution under high pressure in the presence of nickel as a catalyst . It is also possible to reduce resorcinol using sodium amalgam .
properties
1,3-Cyclohexanedione is a light brown solid that is soluble in water. The compound forms chains or rings in solid form, with one of the two keto groups (–C = O ) rearranged with an adjacent hydrogen atom to form an enol (= C – OH) and hydrogen bonds can thus be formed.
use
1,3-Cyclohexanedione is used for the production of mono- and bis-silyl enol ethers. It reacts with primary amines to β-Aminoenonen, to the m -aminophenols by oxidation with acetate mercury (II) , Hg (OAc) 2 , flavored can be.
