Temperature

Procedure

800 Parts of nonylphenol, 98.2 part of paraformaldehyde and 10.9 parts of oxalic acid are charged into a reactor equipped for heating, stirring, reflux, distillation and vacuum. The reactor contents are heated under reflux to 100° C. and held for 4 hours until the refractive index of the vessel contents have reached a maximum. After this time the reactor is converted for distillation and the pressure in the reactor reduced to 100 torr over 1 hour. At the same time the temperature of the vessel contents is allowed to rise to 130° C. During this time about 58 parts of water are collected in the receiver. The vessel is then discharged to yield 851 parts of nonylphenol-formaldehyde resin.
