Ester separation from other liquids after esterification can be achieved through fractional distillation, with efficiency dependent on the boiling point differences of the components involved. Concerns were raised about the appropriateness of using fractional distillation in this context, but it is generally considered a correct method for separation. The discussion also touches on the concept of transesterification, which may be relevant to the esterification process being referenced.

After esterification, can the ester be separated from other liquids using fractional distillation?
I don't see why it couldn't, though the difference in boiling points would determine how efficient it was.

ok thanks. that was a planning exam i just did, and some people said fract. distillation is wrong, i just wanted to make sure that it is "correct" to do it.
Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert?
What is so special with a full p orbital?
Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive.
Can someone explain it to me?
Thanks!!
