    • This invention provides a novel process for preparing soluble phthalocyanines by microwave irradiation in the absence of any organic solvent. Three different starting materials, i.e. t-butylphthalic anhydride, t-butyl phthalonitrile and metal-free H2Pc (tetra-t-butylphthalocyanine) have been adopted , respectively. The starting material with proper metal compound, such as chloride or acetate were irradiated in a commercial microwave oven for a period of 1 to 30 minutes at a power of 200null900 W. This process is noted to reduce drastically reaction time of MPc formation from 8null24 hours to 10null30 minutes due to its unique heating by microwave irradiation. Sandwiched type MPc2(such as Lu Pc2) can be produced only through metal replacement from metal-free phthalocyanine by microwave irradiation.
    • 本发明提供了在不存在任何有机溶剂的情况下通过微波照射制备可溶性酞菁的新方法。 分别采用三种不同的原料,即叔丁基邻苯二甲酸酐,邻苯二甲酸叔丁酯和不含金属的H 2 Pc(四叔丁基酞菁)。 在200〜900W的功率下,在商业微波炉中照射具有合适金属化合物(如氯化物或乙酸酯)的起始材料,时间为1至30分钟。该过程注意到可以大大减少MPc形成的反应时间 8〜24小时至10〜30分钟,由于微波照射独特加热。 三明治型MPc2(如Lu Pc2)只能通过微波照射从金属替代无金属酞菁中生产。
