for the substance; naphthaline was derived from naphtha, a general term for a volatile, fl ammable, hydrocarbon liquid. Michael Faraday (1791–1867) determined the correct empirical formula for naphthalene in 1825, and Richard August Carl Emil Erlenmeyer (1825–1909) proposed the fused benzene ...
Some naphthalene salts of cobalt, chromium, and manganese can be employed as metal catalysts in the oxidation of acetaldehyde. The chemical equation for this reaction can be written as: O2+ 2CH3CHO → 2CH3COOH Ethylene (C2H4) can be oxidized into acetic acid with the help of a palladium cat...
