Reaction Conditions

Reaction Steps

A phenol-formaldehyde solution was prepared in the following manner: 100 g phenol were melted and heated to approximately 80° C. 50 g paraformaldehyde were added whilst stirring. After about 30 minutes all the paraformaldehyde had decomposed and dissolved in the phenol. The mixture was maintained at 80° C. for a further 3 - 5 hours. In this way there was obtained a hardenable solution of low viscosity of formaldehyde in phenol at a mixing ratio of 1:2, said solution being clear even at room-temperature.
