摘　　要：利用L9(3 4)正交表选择进料质量分数 (A) ,反应压力 (B) ,生产负荷 (C)三因素进行优化。试验结果表明 ,A对产品中的 4 CBA含量影响最大 ,其次是B ,而C的作用最小。在Pd/C催化剂活性中期 ,TA产品质量相对稳定的前提下的最佳工艺参数的组合是A1 B3。By using the L_9(3~4)orthogonal table,three factors such as in-feeding mass fraction(A),reaction pressure(B) and producing load(C) were selected to be optimized.The test results showed that the effect of A on product 4-CBA content was the highest,the effect of B was higher,the effect of C was low.When Pd/C catalyst was in its active middle-term,the TA product quality was relatively stable,the optimum process parameter group was A_1B_3.Verification and application of them on practicle production was carried out.
