WebHydrogenation of phenol is an important strategy to produce cyclohexane or cyclohexanol as both of them are raw materials for the synthesis of nylon-6 and nylon-66. Herein, we report a novel method for the selective hydrogenation of phenol to cyclohexane or cyclohexanol over a bifunctional Pd/NaY catalyst by regulating the solvent polarity.

WebFeb 28, 2024 · As can be seen from Fig. 3 c, the conversion of phenol is only 42.11% when the molar ratio of FA to phenol is 1:1 due to the restricted amount of hydrogen source, as it requires at least a 2:1 of the molar ratio of FA to phenol to form cyclohexanone and 3:1 of it to form cyclohexanol. With the ratio increasing from 1 to 3 and above, the ... WebDabei wird ein Gemisch aus Cyclohexanon und Cyclohexanol gebildet, welche man auch abgekürzt als Anon und Anol bezeichnet.
