Web22. mar 2024 · Only salicylic acid (2-Hydroxybenzoic acid) on decarboxylation gives phenol. Complete answer: We must know that salicylic acid will give phenol with CaO and NaOH . The mixture of CaO and NaOH is called soda lime. When we heat carboxylic acids with soda lime, they undergo decarboxylation. WebThe reason is in the different degradation pathways that phenol and salicylic acid follow under photocata- lytic conditions. The treatments are thus effective in inhibiting the degradation pathways initiated by TiIV-øOHsurf (also named øOHa,•s), as in the case of phenol, but much less effective towards electron-transfer ...
