Hello SDN Family,
I have question about lab techniques!
What is exactly Azeotrope and Steam distillation?
Destroyer explained but I still don't process the concept!
Thanks

We use steam distillation when dealing with very high boiling mixtures such as oils.Steam distillation refers to a process in which live steam is in direct contact with the distilling system in either batch or continuous operation. The basis of steam distillation rest on the fact that water forms immiscible mixtures with most organic substances, and these mixtures will boil at a temperature below that of either water or the other materials. This is a very desirable feature, especially if the organic compound has a high boiling point at which it may be unstable or decompose.

An azeotrope is a solution that RETAINS its composition when distilled. Boiling a 95% (w/w) ethanol solution in water would produce a vapor that is 95% ethanol. Distillation cannot be used to obtain higher percentages of ethanol. As far as the DAT goes,,,,,,make sure you are clear on these definitions.....and understand that the distillation process is based on different boiling points . The material must be VOLATILE. If a compound is non-volatile techniques like TLC is done.

I hope this helps.
