Conversion of unrefined phthalocyanine blue from red tone to green tone at aqueous phase environment

通过碾磨粗制酞菁和水介质的分散体系将粗制酞菁蓝由红色转化为绿色的方法，水介质包含粒状研磨辅助料和表面活性剂研磨助剂组合物，特征为使用包含通式I和II的炔二醇表面活性剂于表面活性剂研磨助剂组合物中：∴式中R#+[1]和R#+[2]可以相同或不同，是C1-C8烷基，R#+[3]是氢或甲基，R#+[4]是氢、甲基、乙基，或其任何相结合，m+n＝1到100的平均值。 A method for converting crude phthalocyanine blue from red to green by milling a dispersion of the crude phthalocyanine and an aqueous medium containing a particulate grinding aid and a surfactant grinding aid composition characterized by employing a surfactant grinding aid composition comprising an acetylenic diol surfactant of the general formulas I and II: where R and R , which may be the same or different, are C1-C8 alkyl, R is hydrogen or methyl, R is hydrogen, methyl, ethyl, or any combination thereof, and m + n = an average value from 1 to 100.
