Abstract
A salt of an acrylamidoalkanesulfonic acid can be conveniently prepared by preparing a solid mixture of a normally solid acrylamidoalkanesulfonic acid and a basic compound which is reactive with the acrylamidoalkanesulfonic acid to form the salt. The solid mixture is combined with a solvent in which neutralization of the acrylamidoalkanesulfonic acid occurs.
