Advantages of manufacturing process of copper phthalocyanine blue

phthalocyanine production technology project informationcopper phthalocyanine dyes are produced by introducing solubilizing groups, such as one or more sulfonic acid functions in cpc structure. these dyes find extensive use in various areas of textile dyeing (direct dyes for cotton), for spin dyeing and in the paper industry.copper phthalocyanines pci magserendipitiesstructurereaction of phthalonitrile and cupric chloridereaction of phthalonitrile and cuprous chloridecrystal modificationsthermodynamic stability of b modificationpreparation of b modificationsurface treatmentacknowledgmentsreferences1. in 07, braun and tchermiac tried to synthesize ocyanobenzamide by dehydrating phthalamide using acetic anhydride (scheme 1). the scientists failed to get the desired product but instead got a small quantity of a bright bluish compound that was later known as metalfree phthalocyanine. unfortunately, the scientists failed to recognize the significance of their discovery. 2. it took another s for the second accidental synthesis of the phthalocyanine moiety. swiss chemists von der weid and de dipper phthalocyanine pigment manufacturers, suppliersfind listing of copper phthalocyanine pigment, copper phthalocyanine pigment manufacturers, suppliers, dealers exporters from india. get copper phthalocyanine pigment at best price from listed companies as per your buying requirements.phthalocyanine blues printwikiit is the most commonly used cyan in process color printing, as it is usable in every type of ink and printing process.
