| | The liquid-liquid equilibrium data for ternary systems: propionic acid-ethyl aceta te-water at 15℃, butyric acid-ethyl acetate-water at 15° and 30℃, and mixed acids (acetic, propionic, butyric acid)-ethyl acetate-water at 15℃ were determined. Thevapor-liquid-equilibrium data for binary systems of acetic-propionic acid, propionicbutyric acid, and acetic-butyric acid under normal pressure were also given. The authors regarded that the non-ideal behavior of vapor-liquid equilibrium is mainly ... | | 测定了15℃时丙酸,15℃及30℃时丁酸和15℃时乙、丙、丁混合酸在乙酸乙酯和水中的液-液相平衡数据。也测定了乙酸-丙酸,丙酸-丁酸及乙酸-丁酸三个二元系统在760毫米汞柱压力时的汽-液平衡。我们认为汽-液平衡的非理想主要是由于汽相分子的缔合。于是推导了计算分子缔合时的汽-液平衡关系式,推算的乙酸-丁酸二元系统的汽-液平衡数据和实验结果相符合。 | | 文摘来源 | | The distribution coefficients, Kd, between Zn(Ⅱ) or Cd(Ⅱ) in solutions of different concentrations of hydrochloric acid and acetone and anion exchange resin were determined and the relation between Kd and the composition of the eluent was studied. It was found that when Kd is under 10, the desorption is good, and when Kd is greater than 90, the adsorbed ions cannot be eluted. When 0.01N HCI-30% acetone was used as the eluent, Zn(Ⅱ) cOuld be satisfactorily separated from equivalent or less than equivalent qu... | | 测定了Zn(Ⅱ)和Cd(Ⅱ)在不同濃度的盐酸和丙酮溶液和阴离子交換剂之間的分配系数,Kd,討論了Kd和濃度之間的关系。发見Kd在10以下的冲洗效果好,在15以上的有拖尾現象,大於90的則不被冲洗。如果以0.01N HCl-30%丙酮做为Za(Ⅱ)的冲洗剂,可使大量Zn(Ⅱ)和等量或少量Cd(Ⅱ)分离。用0.01N NH_4Cl-30%丙酮溶液和0.01NNaCl-30丙酮溶液做为Zn(Ⅱ)的冲洗剂,可得到同样的結果。在根据分批平衡实驗結果选擇冲洗剂来分离离子时,不仅要象一般論文中所指出的那样依据分离因数,α,且須考虑分配系数,Kd。在Kd較大的离子的量远此Kd較小的离子的量为大时,因为量大时会提前被冲出的原因,还要顾到它們的比例。 | | 文摘来源 | | This is an introduction of toluene disproportionation catalyst evaluating Set-semi-pilot plant scale moving bed, simulting the industrial conditions. The catalyst charge is about 5 Kilograms, the effective capacity of reactor is 670 milliliters. The over-all structure of this semi-pilot plant scale moving bed reactor is disigned to be analog of the catalyst recycling system of the commercial apparatus. Thus, the catalyst moved continuously through the co-axially instullated reactor and regenerator, an... | | 介绍一种近似模拟工业条件的甲苯歧化催化剂评价装置──小型移动床, 其催化剂初装量约5公斤,反应器有效容积670毫升。小型移动床的总体型式 仿造了工业装置的催化剂循环系统,即催化剂连续移动经过同轴式安装的反应 器与再生器,然后再由空气提升器输送到循环贮斗。甲苯歧化过程未被传质、 传热因素所复杂化,故反应器线型尺寸的设计主要考虑了使反应停留时间及其 分布状况与工业设备相同与近似。在这种小型装置上,一般经过大约500小时 连续运转,即可得到催化剂的平衡活性、选择性、积炭与再生性能指标,并与 工业结果有很好的一致性。此外还可同时得到催化剂机械强度的相对参考指 标,以及经过相当长时间的连续运转可大致估计催化剂的寿命。结论认为,小 型移动床是较全面而有效的催化剂评价装置。 | | 文摘来源 | |   | | << 更多相关文摘 |
