The acetic acid should be as concentrated as possible (glacial acetic acid).

Dangerous substance information

Equipment needed

2 test tubes
rubber plugs with hole and discharge tube
stand with double sleeve and clamp
beaker or the like
burner (preferably alcohol)

Test procedure



Esterification is a balance reaction. Due to the dehydrating effect of concentrated sulphuric acid and the distilling off of the product the balance is shifted in the desired direction. Compared with the Demonstration of ethyl acetate the product is less volatile, therefore the increased admixture of sulphuric acid. Esterification with distillation has herewith reached its limit of practical applicability, for a demontration of a low-volatility ester see Demonstration of ethyl benzoate.
