General description

Ethanesulfonic acid participates in electrolytic reduction of perrhenate solutions.

Ethanesulfonic acid is a sulfonic acid, commonly used as a catalyst for alkylation and polymerization reactions.

Application

Ethanesulfonic acid is used as an esterification catalyst in the pre-treatment of ACPO (acidic crude palm oil) to produce biodiesel.
