Phthalocyanine compound synthesizer

Abstract

The invention discloses a phthalocyanine compound synthesizer. The phthalocyanine compound synthesizer comprises a first reaction kettle, a first condenser, a second reaction kettle and a second condenser, wherein the first reaction kettle is communicated with the second reaction kettle by a first material conveying tube; a first gas inlet, a first gas outlet, a first solvent reflux opening and a first water outlet are formed on the first condenser; the first reaction kettle is communicated with the first gas inlet by a first mixed gas conveying tube; the first solvent reflux opening is communicated with the first reaction kettle by the first solvent reflux tube; a second gas inlet, a second gas outlet, a second solvent reflux opening and a second water outlet are formed on the second condenser; the second reaction kettle is communicated with the second gas inlet by the second mixed gas conveying tube; the second solvent reflux opening is communicated with the second reaction kettle by the second solvent reflux tube; and the second gas outlet is communicated with the first reaction kettle by a third mixed gas conveying tube. The phthalocyanine compound synthesizer disclosed by the invention effectively controls generated moisture, improves ammonia gas yield, recycles a carrier solvent and ensures safety and continuity of operation.

Description

technical field

[0001] The invention relates to equipment for producing phthalocyanine compounds, in particular to a phthalocyanine compound synthesis device suitable for producing phthalocyanine compounds by a two-step solvent method. Background technique

[0002] The production methods of phthalocyanine compounds are divided into solid-phase method and solvent method.

[0003] Due to the poor heat and mass transfer effect of the phthalocyanine compound produced by the solid phase method, it is difficult to fully mix the materials, and the temperature in the system is not uniform, so the product yield is low, the quality is poor, the color is not bright, and it is difficult to realize large-scale industrial production.

[0004] The production of phthalocyanine compounds by solvent method is more widely used because of overcoming the above-mentioned shortcomings. The solvent method is divided into one-step method and two-step method. Compared with the one-step solvent meth...
