摘要:
This invention relates to methods for the production of sodium, potassium, rubidium, cesium, magnesium, manganese, cobalt, nickel, aluminum, copper (II) and zinc salts of 5-sulfoisophthalic acid. In addition, this disclosure describes new compositions of matter, specifically, the rubidium, manganese, cobalt, nickel, and copper (II) salts of 5-sulfoisophthalic acid. The method utilizes the addition of metals salts to a crude sulfonation solution of 5-sulfoisophthalic acid.
