| General description: | 1-Naphthol is a hydroxyl-aromatic compound. Its thermodynamic properties such as heat capacity, sublimation pressure, vapor pressure, enthalpies of combustion, formation and fusion have been estimated. The decomposition of 1-naphthol in aqueous solutions on exposure to gamma radiation has been studied. The ability of biochar of orange peels in adsorbing 1-naphthol from water has been investigated. The activation energy and the reaction rate constant of the enzymatic polymerization of 1-naphthol using laccase have been reported. It undergoes hydrogenation in the presence of a rhodium catalyst to form cis,cis 1-decalol. This product is a certified reference material (CRM) certified to International Standards BS EN ISO / IEC 17025 and ISO 17034 under UKAS accreditation. |
