[0046] In a second aspect, the present application provides a method for preparing the above-mentioned metal phthalocyanine salt modified polyol, the preparation method comprising the following steps:
[0047] S1: In an inert atmosphere, and in the presence of a first basic catalyst, reacting 4-nitrophthalonitrile and a polyhydric alcohol in a first organic solvent at a first reaction temperature for a first predetermined period of time, obtaining phthalonitrile-terminated polyols; and
[0048] S2: In an inert atmosphere and in the presence of a second basic catalyst, make phthalonitrile, the metal salt and the phthalonitrile-terminated polyol obtained in step S1 in a second organic reacting in a solvent at a second reaction temperature for a second predetermined period of time to obtain the metal phthalocyanine salt-modified polyol.
[0049] In a specific embodiment, the preparation method of metal phthalocyanine salt modified polyol described herein comprises K 2 CO 3 , 4...
Embodiment 1
[0084] Will K 2 CO 3 (82.8g, 0.6mol), 4-nitrophthalonitrile (51.9g, 0.3mol) and PCL205U (633.6g, 1.2mol) were added to the reaction flask, under the protection of nitrogen, heated to 60 ° C, stirred for 24 Hour. After the reaction finishes, add phthalonitrile (38.4g, 0.3mol), ZnCl 2 (40.8g, 0.3mol), DBU (300ml) and DMF (800ml), the mixture was heated to 150°C under nitrogen protection and kept for 8 hours. After the reaction, cool to room temperature, first add water to precipitate, and wash the filtered solid with water until neutral. The solid was redissolved with ethyl acetate, the insolubles were filtered off, and then ethanol was added for precipitation. The filtered solid was dried in a vacuum oven to obtain zinc phthalocyanine modified polycaprolactone polyol (342.0g), and the hydroxyl value was measured It is 58.2mgKOH / g.
Embodiment 2
[0086] Will K2 CO 3 (82.8g, 0.6mol), 4-nitrophthalonitrile (51.9g, 0.3mol and BDO (108.1g, 1.2mol) were dissolved in DMF (800ml), under nitrogen protection, heated to 60 ° C, stirred Reaction 24 hours. After the reaction finishes, add phthalonitrile (38.4g, 0.3mol), ZnCl 2 (40.8g, 0.3mol), DBU (300ml), and the mixture was heated to 150°C under nitrogen protection for 8 hours. After the reaction, cool to room temperature, first add water to precipitate, and wash the filtered solid with water until neutral. The solid was re-dissolved with DMF, and then ethanol was added for precipitation. The filtered solid was dried in a vacuum oven to obtain butanediol-grafted zinc phthalocyanine (153.4 g), and the measured hydroxyl value was 152.1 mgKOH / g.
