Question

How is formalin and trioxane related to methanol?

Answer 1

Formalin is 40 % solution of HCHO, which is 
obtained by the oxidation of methanolCH3OH −→(O) HCHO Formalin is used to preserve biological  specimen.Trioxan is obtained by the acid  catalysed conversion of formaldehyde to a  polymer.

Answer 2

Methanol contains 40% of aqueous solution is known as formalin and trimer of methanol known as trioxane.

Explanation:

Formalin

• 40% of aqueous solution which is water solution of formaldehyde is used.
• HCHO is the chemical formula and pungent gas is used to form as disinfectant and antiseptic.
• It is high toxic and systematically poisonous.
• It smells as pickle like odor.

Trioxane

• In formaldehyde trioxane is used as anhydrous source.
• Trimer of methanol known as trioxane.
• Trimerization occurs in formaldehyde and its catalyst is acid  to form trioxane.
• The reaction occurs by aqueous solution which is concentrated and solvent extraction separates the product.
