Methods of ultramarine production using synthetic zeothetic zeolites as substrates have been developed. In contrast to the conventional method the emission of sulfur oxides is almost negligible. Intense blu products having the sodalite (SOD) structure have been obtained by the calcination of zeolites A, X, Y and hydroxysodalite impregnated with sulfur compounds (mainly sodium polysulfides). An attempt has been made to introduce into zeolites the S3−radicals generated in DMSO solutions of polysulfides.
