Introduction to properties of formaldehyde:
Formaldehyde is defined as an organic compound. Mainly this formaldehyde are used for the polymers. The chemical formula used for the formaldehyde is CH2 O. Formaldehyde is present in the substance like carbon, hydrogen and the oxygen. 90 percent of formaldehyde are present in the atmosphere itself. The other name for this is oligomers. The synttesis of formaldehyde is got from the industrial solution.
Various properties of formaldehyde
There are mainly two properties are present for the formaldehyde. They are defined in the following,
1. Physical properties
2. Chemical properties
Explanation for physical properties of formaldehyde
I like to share this Alcl3 Molar Mass with you all through my article.
Physical Properties:
Explanation for chemical properties of formaldehyde
The chemical properties of formaldehyde are given below,
1. Reaction of formaldehyde with sodium hydroxide
2. Reaction of formaldehyde with amines
3. Reaction of formaldehyde with ammonia
Reaction of formaldehyde with sodium hydroxide:
Two molecules present in the formaldehyde get reacted with one molecule present in alkali. In this reaction, one of the molecule is reduced to the group of methyl alcohol and another molecule is oxidized. Thus forming an formic acid.
2HCHO + KOH `->` CH3 OH + HCOOK
Where,
KOH = Potassium hydroxide
CH3 OH = Methanol
HCOOK = Potassium formate
Reaction of formaldehyde with amines:
Primary amines and secondary amines are present in the formaldehyde. These two reacts with the ethyl amine and produces a ethylmethylamine.
2HCHO + C2 H5 NH2 `->` C2 H5 NH. CH3 + HCOOH
where,
HCHO = Formaldehyde
C2 H5 NH2 = Ethyl amine
C2 H5 NH. CH3 =Ethyl-methyl amine
HCOOH = Formic acid
Reaction of formaldehyde with ammonia:
The reaction of ammonia with the formaldehyde produces an hexamethylenetetramine. The reaction is follows,
6HCHO + 4NH3 `->` ( CH2 )6 N4 + 6 H2 O
where,
HCHO= formaldehyde
( CH2 )6 N4 = hexamethylenetetramine
