1. The reaction of obtaining chloroform by the action of alkali on chloral hydrate.
Cl3-CHO • H2O + NaOH = Cl3-CH + H2O + HCI-ONa.
The reaction takes place with slight heating, the appearance of a sweetish smell of chloroform.
2. Iodoform can be obtained by the following reactions:
Iodization of ethyl alcohol in the presence of alkali.
CH3CH2 (OH) + 4J2 + 6KOH = CHJ3 + HCOOK + 5KJ + 5H2O.
The action of potassium iodide on acetone at the time of its receipt from KJ and NaClO.
KJ + NaClO = KJO + NaCl.
CH3COCH 3 + 3KJO = CHJ3 + CH3COOK + 2KON.
