Acetonitrile treatment
Thread Content
I want to use acetonitrile, but it contains thionyl chloride. I would appreciate it if you experts could advise me on how to deal with this. Thank you.
Although their boiling points are quite close, distillation can definitely be used to achieve separation and recovery. Perhaps we could explore this option: lol
Thank you for your advice. How tall does a distillation tower need to be? What is the appropriate temperature to maintain?
It depends on both the recovery rate and the processing volume. For example, if the processing volume is low, the diameter of the tower is small; however, separation becomes difficult, resulting in a very tall and narrow tower. In such cases, it is necessary to increase the reflux ratio appropriately, or special distillation methods might also be used. If needed, we can discuss this in more detail； If you are working on a graduation project, it is recommended that you find materials and search for literature on your own; this will be somewhat helpful for your future career
Haha, sulfuryl chloride requires a distillation tower with anti-corrosion measures; either neutralize it first and then distill it. They ask about tower height and temperature control right from the start; just by hearing that, it’s clear they don’t understand distillation. If you really have a large amount of material, you can consider adding distillation equipment ； If you have a small amount of material and a distillation tower, you can ask others for advice, then look up relevant literature and try to carry out the distillation process on your own ； If the above two conditions are not met, then there’s nothing else to do but laugh: lol
What is the composition of the poster? What are the separation requirements? I have been engaged in the design of distillation separation processes and the development of process packages for a long time; if you need any assistance, please send a message to my email address: 464624808@qq.com.
Their boiling points are roughly the same. Add water, perform azeotropic distillation, and then dehydrate using a molecular sieve.
Dichlorosulfoxide reacts with water and cannot be used.
The reaction produces sulfur dioxide and hydrogen sulfide, hehe
