Inhibition of crystal formation of 1,2-dimethyl-3,5-diphenylpyrazolium methyl sulfate in aqueous solutions with an acrylamide polymer

摘要

The present invention relates to a liquid composition comprising a water soluble acrylamide polymer, 1,2-dimethyl-3,5-diphenylpyrazolium methyl sulfate, a surfactant and water. More particularly, this invention relates to the use of a water soluble hydrolyzed acrylamide polymer for the inhibition of partial recrystallization of 1,2-dimethyl-3,5-diphenylpyrazolium methyl sulfate from aqueous solutions thereof.
