tpeepreparation of nylon 66 salt
nylon 66 salt are prepared respectively the temperature ethanol ethanol solution with adipic acid hexanediamine at 60 deg c above the mixing and salt precipitation, filtering, alcohol washing, drying, and finally preparing aqueous solution of 63%, use for polycondensation. the reaction formula is as follows:
polycondensation
the polycondensation of nylon 66 salt should be carried out at high temperature, with the removal of water, resulting in the formation of linear high molecular weight nylon 66. the reaction formula is as follows:
the production process is divided into two kinds: intermittent method and continuous method. continuous method is suitable for large-scale production, and the production of nylon 66 in the world mainly adopts continuous method. the batch method is used only in two cases: one is to produce special or experimental grade; two is in a small device with a production capacity of 4 500t a.。
