摘要：
A method for preparing organic products from aqueous solutions, such as waste or byproduct liquid streams and waste or byproduct gas or vapor streams, uses phase transfer catalysis to transfer a chemical species in low concentration from the aqueous solution to the organic phase or the aqueous-organic interface. The system has little or no organic solvent, and the organic phase contains an electrophile which participates in the reaction. In one embodiment, the aqueous solution is contacted with the electrophile and a phase transfer catalyst and, optionally, a pH adjusting agent in the event that the chemical species in the aqueous solution is not sufficiently ionized to react with the electrophile, and optionally an organic solvent. A method for continuously converting a chemical species involves this contacting step, separating the phases, then dividing the organic phase into the product, the phase transfer catalyst, and the optional organic solvent.
摘要（中）：
从诸如废物或副产物液体流以及废物或副产物气体或蒸汽流的水溶液制备有机产物的方法使用相转移催化剂将低浓度的化合物从水溶液转移到有机相或含水溶液中， 有机界面。 该系统几乎没有或没有有机溶剂，有机相含有参与反应的亲电子试剂。 在一个实施方案中，水溶液与亲水性试剂和相转移催化剂以及任选的pH调节剂在水溶液中的化学物质没有充分离子化以与亲电试剂反应的情况下，以及任选的有机物 溶剂。 连续转化化学物质的方法涉及该接触步骤，分离相，然后将有机相分成产物，相转移催化剂和任选的有机溶剂。
