    • The present invention relates to a process for the preparation of metal-free phthalocyanines of the formula I by conversion of an ortho-phthalodinitrile of the formula Ia in an inert solvent with a boiling point of at least 120° C. (at standard pressure) in the presence of ammonia, in which, in formula I or Ia, the variable n can adopt values of 1, 2, 3 or 4 and the R radicals denote a five- or six-membered saturated nitrogen-comprising heterocyclic ring optionally substituted by one or two C1-C8-alkyl groups which is bonded via a ring nitrogen atom to the benzene ring and which can still comprise one or two additional nitrogen atoms or an additional oxygen or sulfur atom, which comprises carrying out the conversion in the presence of an alkali metal hydroxide or alkali metal carbonate.
    • 本发明涉及通过在沸点至少为120℃的惰性溶剂中(在标准压力下)转化式Ia的邻苯二甲腈,制备式I的无金属酞菁的方法, 在氨的存在下,其中在式I或Ia中,变量n可以采用1,2,3或4的值,并且R基团表示五或六元饱和含氮杂环,任选地被 一个或两个通过环氮原子与苯环键合并且还可以包含一个或两个另外的氮原子的C 1 -C 8 - 烷基或 另外的氧或硫原子,其包括在碱金属氢氧化物或碱金属碳酸盐的存在下进行转化。
