Conditions

Temperature: 40 °C

Procedure

The mixture is cooled to 40° C, 470 g of phenol is added thereto, together with 665 g of (90%) paraformaldehyde, following by stirring for 1 hour at 40° C. Then over a period of 1 hour 300 g of (33%) caustic soda solution are added and the temperature is held at 40° C until the free formaldehyde content is below 1.5%. This lasts a further 3 to 4 hours, calculated from the paraformaldehyde addition.

Workup

waitThis lasts a further 3 to 4 hours
