The phthalocyanine derivatives can improve the stability and thermal characteristics of plastics. o Phtahalimide (N) prepared from the reaction of phthaloanhydride with urea reacted、 with formaldehyde to get N hydroxymethyl phthalimide(H), and then the latter was sulfonated with fuming sulfuric acid to get the final product phthalimidomethyl copper phthalocyanines(S). The reaction conditions were optimized through adjusting the proportion of reactants, temperature and reaction time in synthesis and the structures of the products were confirmed. The conditions of solid phase reaction were easy to control, and the use of solvent was saved avoiding undesirable by products. The yield of N was up to 95% on the basis phthaloanhydride. In the synthesis of H, pH was a key factor and the yield reached 96%. The influence of reaction temperature and the amount of sulphonated agent was important in the synthesis of S.
