Ethanesulfonic acid Usage And Synthesis

Description

Ethanesulfonic acid (esylic acid) is a sulfonic acid with the chemical formula CH3CH2SO3H. The conjugate base is known as ethanesulfonate or, when used in pharmaceutical formulations, as esilate. It is a colorless liquid.

Uses

Ethanesulfonic acid is an alkanesulfonic acid in which the alkyl group directly linked to the sulfo functionality is ethyl, and it is a conjugate acid of an ethanesulfonate. employed in the electrolytic reduction of perrhenate solutions. Ethanesulfonic acid is used as pharmaceutical intermediates, catalyst of polymerization and alkylation. It participates in the electrolytic reduction of perrhenate solutions.

structure and hydrogen bonding

This compound belongs to the class of organic compounds known as organosulfonic acids. These are compounds containing the sulfonic acid group, which has the general structure RS(=O)2OH (R is not a hydrogen atom).

Preparation

(1) To a glass reactor equipped with a reflux condenser, sample inlet, internal cooler, stirring device and solvent was distilled off with an opening and closing cock was charged with 60weight % of hydrogen peroxide solution 295 g (5.20 mol) prepared and 154 g (1.00 mol) of bis(2-hydroxyethyl)disulfide was uniformly added from the sample inlet over 150 minutes and the liquid was stirred. During this time, the temperature of reaction liquid was held at 45 °C by flowing 19 °C cooling water at the flow rate of 140mL/minutes into the condenser. After completion of the addition, the reaction solution temperature was maintained at 50 °C for 2 hours and heated under reflux for 4 hours.
