摘　　要：提出了间歇精馏过渡馏分的脉动操作方式，模拟计算和实验研究结果证明，此操作方式可有效改善间歇精馏过渡馏分馏出的操作状况，在计算和实验条件下，可使固定操作时间内的过渡馏分馏出量比恒回流比操作降低３０％左右。A pulse-distillation method of intermediate cut in batch distillation is proposed. The result of simulating calculation and experimental study prove that the new operation is beneficial for the distillation of intermediate cut. Under the condition of the calculation and experiments, amount of the intermediate cut during fixed time of the pulse-distillation operation can be reduced by 30% than that of constant reflux ratio operation.
