Abstract

Способ изготовления фенолоформальдегидного олигомера, включающий загрузку фенола, загрузку воды, загрузку первой порции едкого натра, загрузку формалина и загрузку второй порции едкого натра, отличающийся тем, что формалин, перед загрузкой в реакционную смесь и до введения второй порции едкого натра, смешивают с раствором параформальдегида с последующей нейтрализацией смеси гранулированным едким натром.A method of manufacturing a phenol-formaldehyde oligomer, comprising loading phenol, loading water, loading the first portion of caustic soda, loading formalin and loading a second portion of caustic soda, characterized in that formalin is mixed with paraformaldehyde solution before being loaded into the reaction mixture and before the second portion of caustic soda is introduced. followed by neutralization of the mixture with granular sodium hydroxide.
