摘要： A method for producing bis-2-hydroxyethyl terephthalate is disclosed. The method includes the steps of: (1) adding a waste polyester raw material into a co-extruder to obtain a co-extrudate; (2) adding the co-extrudate into a reactor with an agitation shaft and depolymerizing same to obtain a first reaction product; (3) adding the first reaction product into a first continuous stirred tank reactor and depolymerizing same to obtain a second reaction product; and (4) adding the second reaction product into a second continuous stirred tank reactor and depolymerizing same to obtain a third reaction product.
