Question

Thermosetting resins similar to Bakelite (Section 30.7) have also been prepared from renewable feedstocks. One method uses cardinol, the major constituent of the liquid obtained from roasted cashew nutshells. What polymer is obtained when cardinol is treated with formaldehyde (${\mathbf{H}}_{\mathbf{2}}\mathbf{C}\mathbf{=}\mathbf{O}$) in the presence of a proton source?

Short answer

Answer

Formation of cardinol

Step-by-step solution

Cardinol

Isotopes are the species that only differ in the number of neutrons or atomic mass. Cardinol is the major chemical compound used in tablets for Blood Pressure. It is also used in the treatment of chest pain.

Formaldehyde

The gaseous organic chemical made up of carbonyl group with one carbon in the parent chain is formaldehyde. The building materials mainly consist of formaldehyde.

Chemical reaction of cardinol with formaldehyde

In the chemical reaction of cardinol with formaldehyde, three cardinol molecules join through group. The reaction is shown below:

Formation of cardinol
