Hi, whilst revising I came across this:

"An ester can be made by reacting an alcohol with a carboxylic acid. The technique usedinvolves four stages: reflux, distillation, purification and drying.

In the reflux stage, the alcohol and ester are heated with a little concentratedsulfuric acid in a flask with a condenser attached in an upright position. Evaporatedliquid is allowed to run back into the flask.

In the distillation stage, the mixture is placed in a flask connected to a slopingcondenser and heated. The product is collected at its boiling point."

The part I made bold is meant to say "the alcohol and carboxylic acid are heated" right? I can't find much help on esters and so I just want to clarify if the above is true before I try memories the 4 steps, so can someone please confirm?

Thanks.

Question 2b
Yes. Esters are made from an alcohol and a CA so it's a typo.

Esterification is (always, I suspect?) exothermic. If you want a high yield, you'd be better to wait a while and do it at room temp rather than reflux it.

But people these days are always in a Goddamn hurry.

OK, thanks for the verification, appreciate it.
