Principles of Distillation
قالب: : پاورپوینت و پی دی اف مقاله اصلی
Simply, distillation is the process in which a liquid is vaporized (turned to steam), recondensed (turned back into a liquid) and collected in a container. Nature uses a form of distillation to turn salt water (seawater) into fresh water (rain).
What is distillation?
Why do you use distillation to recycle waste solvents?
Why is distillation an ideal way to separate the two?
You say contaminates are typically not volatile, does this mean some are?
What are the differences between simple distillation and fractional distillation?
What is vacuum distillation?
Why do you use vacuum distillation?
When do you use vacuum distillation?
If the maximum heater setting is 392º Fahrenheit, why do I need to use vacuum distillation for solvents with boiling points over 300º Fahrenheit, don’t you mean solvents with boiling points over 392º Fahrenheit?
How is the vacuum created?
