Deoiling of wax is done by its _________________?
Correct answer: B. Both B. & C.
- A. Heating
- B. Both B. & C.
- C. Solvent extraction
- D. Cooling
Explanation
Wax is deoiled by solvent crystallisation: the wax-oil mixture is dissolved in a solvent, cooled to crystallise wax, and then separated. Thus cooling and solvent extraction work together, while heating alone does not remove the oil.
