摘要
The present invention relates to making tetra-sulfo iron-phthalocyanine by reacting sulfonated reactant(s) in the presence a boron-containing promoter. The present invention also relates to making tetra-sulfo iron phthalocyanine more tolerant to oxygen by combining the tetra-sulfo iron-phthalocyanine with a stabilizing amount of a complexing agent (e.g., a stabilizing amine) and/or contacting the tetra-sulfo iron-phthalocyanine with steam.
