Fully negative pressure distillation
Thread Content
I would like to ask what the definition of full negative pressure distillation is I’ve looked up a lot of information but still can’t find a definite meaning????????????????????????
Process requirements, as well as the physical and chemical property requirements for certain materials, for reference.
I’ve looked up a lot of information, but there’s no definite meaning; perhaps it simply doesn’t have one. Essentially, the operation is carried out under negative pressure; the extent of this negative pressure depends on the specific process, with the goal of solving practical problems being the priority – the exact level of negative pressure isn’t that important
Negative pressure distillation is simply distillation under reduced pressure; I’ve really never heard of \"full negative pressure distillation\" – does \"full\" refer to the degree or the process? If it comes to the degree, it is high-vacuum reduced-pressure distillation, with an absolute pressure in the tens range (I’ve never seen one in the single digits) ； If it is a process, then all stages of distillation take place under reduced pressure.
Vacuum distillation is distillation under negative pressure
Okay, thank you\ud83d\ude00
