WebRXNO:0000032. In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl ( C=O) functional group by formaldehyde ( H−CHO) and a primary or secondary amine ( −NH2) or ammonia ( NH3 ). [1] The final product is a β-amino-carbonyl compound also ... WebPhenol is a nonspecific protoplasm poison that has an optimal antibacterial effect at 1% to 2%. Many dental preparations use much too high a concentration of phenol (e.g., in the … Many phenols of commercial interest are prepared by elaboration of phenol or cresols. They are typically produced by the alkylation of benzene/toluene with propylene to form cumene then O 2 is added with H 2SO 4 to form phenol (Hock process). In addition to the reactions above, many other more specialized reactions produce phenols: • rearrangement of esters in the Fries rearrangement busara food
