HCID 172281Formaldehyde;phenol

Procedure

Phenol was heated in an oven at about 70° C. for about 30 minutes, and then 1 g of the phenol was put into a microtube and a 20% NaOH aqueous solution of 200 μl was added dropwise. Then, a 37% formalin aqueous solution of 1 ml was added thereto for a reaction at about 70° C. for about 60 minutes. Thereafter, a 0.6 M chloride aqueous solution was dropped so as to neutralize pH to 7.0 and dried in a vacuum for about 24 hours and melted at a mass fraction of about 50% in ethanol to produce a phenol-formaldehyde resol to be used as a carbon precursor.
