分子蒸馏脱除核桃油中塑化剂工艺优化Optimization of removal of plasticizers from walnut oil by molecular distillation
Zhongguo youzhi, 2022 为探索利用分子蒸馏脱除核桃油中塑化剂的合理工艺，采用单因素实验考察了蒸馏温度、进料速度和刮膜转速对核桃油中塑化剂DEHP和DBP脱除的影响，在此基础上以DEHP和DBP的含量为指标，运用响应面法对分子蒸馏脱除核桃油中塑化剂的工艺条件进行优化。结果表明：分子蒸馏脱除核桃油中塑化剂的最佳工艺条件为蒸馏温度150 ℃、进料速度250 mL/h、刮膜转速260 r/min，在此条件下核桃油中DEHP含量为0.56 mg/kg，DBP含量为0.05 mg/kg,符合我国对食品中DEHP、DBP的限量要求（DEHP≤

Gongye shui chuli, 2021 膜蒸馏是一种新型膜分离技术，能同时进行热量与质量的传递。膜蒸馏将膜分离技术与传统蒸发过程结合起来，以多孔疏水膜作为汽、液两相间的屏障，膜两侧的蒸汽压力差为传质推动力，使水蒸气透过膜孔在膜的另一侧冷凝，可实现溶液的浓缩、分离或提纯。采用多效平板膜蒸馏中试装置进行反渗透高盐水的浓缩，优化后的实验条件为：加热温度70 ℃，末端真空压力8~9 kPa，进水流量63 L/h。结果表明：膜蒸馏过程可以实现盐水的高倍浓缩，浓缩液TDS可达240 g/L，产水通量随浓缩液TDS的增加由7 L/（m2·h）降至2.65 ...

Gongye shui chuli, 2003 实验结果表明,水样的pH控制在6.0～8.0范围,可以同时蒸馏水中的苯酚和苯胺,且蒸馏回收率为98%～103%;有取代基的酚类和芳胺在中性蒸馏条件下的回收率,随结构不同回收率不同。中性蒸馏时,氧化剂KClO4,KClO3,KNO3,H2O2(100mg/L以下)的存在对苯酚和苯胺氧化作用很小,误差不超过±5%,KMnO4和K2S2O8对苯酚和苯胺中性蒸馏时,氧化作用比较显著。合成水样经中性蒸馏后,紫外四阶导数法的测定结果与国家环保局推荐方法的测定结果之间精密度和准确度均无显著差异。
