How do we remove the presence of acidic impurities in the manufacture

1.	How do we remove the presence of acidic impurities in the manufacture of isopropanol?(a) Wash water(b) Caustic wash(c) Sulphuric acid(d) Phosphoric acidThe question was asked in final exam.My question is taken from C3 Compounds topic in chapter Synthetic Organic Chemical Industries of Chemical Technology
Answer» Correct answer is (b) Caustic WASH The explanation is: The ISOPROPANOL VAPOURS consists acidic impurities which can be removed with the help of a caustic wash tower. Caustic wash generally consists of caustic soda. Sulphuric acid is used as an ABSORBER in hydration of PROPYLENE.
