Answer 1

What you are asking about is way over my head, but I looked around and found this:

Check it out. It may help.

Answer 2

yeah i was at the same website, but it doesnt explain to me much. Thank you though =)

Answer 3

Are you familiar with what that is?

Answer 4

basically once you get the product you dissolve the product into a solution then recrystal it so get a purer product

Answer 5

in a fisher esterification you produce water, to increase the extent of the reaction, i.e. the yield, you distill off the water produced.
