Question

Salicylic acid is prepared from phenol by:

• A. Reimer-Tiemann reaction
• B. Kolbe's reaction
• C. Kolbe-electrolysis reaction
• D. none of the above

Answer 1

Answer: (A)

Salicylic acid can be prepared from phenol by
Reimer-Tiemann reaction

But if $CHC{l}_3$ is used in place of $CC{l}_4$, salicylaldehyde is formed.

In Kolbe's reaction salicylic acid is prepared by using sodium phenoxide.

In Kolbe's electrolysis simple hydrocarbons are prepared
$\underset{\text{pot acetate}}{2RCOOK}+2HOH\stackrel{\text{ Electrolysis }}{\to }\underset{\text{Alkane}}{R-R+2C{O}_2}+H_2+2KOH$
