| Abstract: | Bisphenol A ( BPA) was prepared from waste polycarbonate (PC) by hydrolysis under atmospheric pressure using 1, 4-dioxane as solvent and NaOH as catalyst. The factors affecting the reaction were studied. Under the optimum conditions of reaction temperature 100 ℃, reaction time 8 h, m(NaOH): m(H_2O + solvent) =1 =33, m(solvent) : m(PC) =4 : 1, m(H_2O) : m(PC) = 1 : 1, the hydrolysis efficiency of PC is over 98% , and the yield of BPA is over 95%. |
