Abstract: A process for producing polyarylene ether nitrile, in which an N-methylpyrrolidone solvent can be efficiently recovered. The process includes the following steps: mixing N-methylpyrrolidone, potassium carbonate, 2,6-dichlorobenzonitrile, dihydric phenol and toluene, and carrying out a dehydration reaction and a polymerization reaction in sequence to obtain a high-viscosity polyarylene ether nitrile solution; then pelletizing and conveying polyarylene ether nitrile particles together with methanol to a primary vibrating screen to complete a primary replacement of N-methylpyrrolidone; then using a secondary vibrating screen to complete a secondary replacement of the solvent; subsequently, grinding the polyarylene ether nitrile particles and carrying out an extraction with methanol, and then centrifuging, washing with water and drying to obtain purified polyarylene ether nitrile powder; and finally distilling replacement liquid and centrifugation liquid to separate methanol from N-methylpyrrolidone.
