  高效可循环利用的烷基硫酸氢铵催化剂，可通过苯酚与甲醛的缩合形成双酚F †

  摘要：

  几种C 1 – C 4烷基硫酸氢盐[R 3 NH] [HSO 4 ]可以方便地从廉价的原料硫酸和烷基胺中制备。通过化学滴定法测量其酸度，并使用紫外-可见光谱法和碱性指示剂4-硝基苯胺进行测定。在间歇反应器上详细评估了这些硫酸氢盐对苯酚与甲醛缩合为双酚F（BPF）的催化性能。结果表明，所提出的催化剂由于在反应条件下的均相催化特性而对这种缩合反应非常有效。在所研究的催化剂中，[H 3 NCH 2 CH 2 NH 3] [HSO 4 ] 2显示出最佳的催化性能，并且可以实现甲醛的完全转化，在最佳条件下对BPF的选择性高于90％。此外，可以通过与环己烷的共沸蒸馏从反应混合物中回收催化剂以除去水，然后过滤，并重复使用六次，几乎没有活性损失，显示出优异的可重复使用性。建议本催化方法结合了均质反应和异质回收的特点，因此可能为合成双酚F提供高效，环保和低成本的途径。

  An ionic liquid as a solvent in the hydration reaction of α-pinene to α-terpineol. The ionic liquid is obtained from the reaction of an amine and an inorganic acid. The use of the ionic liquid as solvent favors the selectivity towards the formation of α-terpineol and once the reaction product has been brought to room temperature, the organic phase can be physically separated from the inorganic one by decantation. The inorganic phase contains the ionic liquid, water and reaction catalyst and can be directly reused for a new reaction batch.

  A method of screening solvents for the solubilization of petroleum hydrocarbons is disclosed. The method includes dissolving petroleum hydrocarbons in a selected solvent to form a first solution, adding an ionic liquid to the first solution and blending to form a second solution and measuring absorbance of the second solution using spectroscopic techniques. The solubilization of petroleum hydrocarbons in the solvent is then determined based on the difference between the measured absorbance of the first and second solution. A system for screening solvents for the solubilization of petroleum hydrocarbons is also disclosed. The system can be used in removal of wax deposition in refinery process equipment, process flow lines, during piping operations, up-gradation of wax, prevention of clogging of pipelines, processing of sludge or for removing sludge from petroleum tank installations and enhancing the crude oil flow.
