Title:
MANUFACTURING METHOD FOR SULFONIC ACID GROUP-CONTAINING ETHER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2010/030024
Kind Code:
A1
Abstract:
Provided are compositions that contain sulfonic acid group-containing ether compounds that have low impurity content and satisfactory radical (co)polyermizability, and a method whereby the generation of by-products can be limited and sulfonic acid group-containing ether compounds having high purity and satisfactory polymerizability can be manufactured efficiently. The manufacturing method for sulfonic acid group-containing ether compounds is a method to manufacture the compounds by reacting a compound represented by general formula (1) and a sulfurous acid compound. The manufacturing method comprises a step to adjust the pH of the reaction system to 5.5 or higher using an alkaline substance, and a step to add a compound represented by the general formula (1) to a reactor in which a sulfurous acid compound is present.
