Liu Yan,Tang Hong,Shi Chong Shanghai Research Institute of Petrochemical Technology,Shanghai 200540
Fatty alcohol polyoxyethylene phosphonate tri-ethanolamine salt was synthesized by using fatty alcohol and ethylene oxide as raw materials, phosphorus pentoxide as an esterification reagent and tri-ethanolamine as a neutralizer. The synthesis process and application of its built finish oil in polyacrylonitrile fiber production were studied. The synthesis process conditions were optimized as followed: mole ratio of ethylene oxide and fatty alcohol 2. 0, mole ratio of fatty alcohol polyoxyethylene and phosphorus pentoxide 3.8, phosphorus pentoxide feeding time 1. 5 h, esterification temperature 70℃ and time 3. 0 h, tri-ethanolamine amount 0. 73 - 0. 76 higher times than fatty alcohol polyoxyethylene phosphonate amount. The built finish oil using fatty alcohol polyoxyethylene phosphonate tri-ethanolamine salt as monomer had the performance equal to the imported ones from Japan.
