で反応させるフタル酸溶剤法が多く用いられている。The method for producing copper phthalocyanine pigments includes (1) reaction of phthalonitrile with copper or copper salt, (2) reaction of phthalic acid, phthalic anhydride, phthalimide, etc. with urea and copper or copper salt in the presence of a catalyst. Many methods are known, such as (3) reaction of orthocyanobenzamide with copper or a copper salt, and (4) reaction of metal-free phthalocyanine with copper salt. Industrial production methods include the 2) IJ sil solvent method, in which phthalonitrile and copper salt are reacted in a solvent inert to the reaction, such as nitrobenzene, and phthalic anhydride, urea, and copper salt are reacted in a solvent such as nitrobenzene or trichlorobenzene. A phthalic acid solvent method is often used.

点となる。To deal with these problems, methods using an alkylbenzene such as polyalkylbenzene having at least one propyl group as a solvent have been proposed in JP-A-49-63735 and JP-A-49-116121. As a result of carrying out the method by the present inventors, the color tone of the crude copper phthalocyanine was stained and unclear, making it impossible to obtain a satisfactory result. In particular, the unclear color tone of crude copper phthalocyanine is a fatal drawback when used in paints, printing inks, and the like.

査検討し、食品衛生上、環境衛生」二無害なものがある
ことに着目し、その使用について研究し、本発明を完成
した。In order to solve this problem, the present inventors researched and considered harmless solvents, and focused on the fact that there were solvents that were harmless in terms of both food hygiene and environmental hygiene, researched their use, and completed the present invention.
従来の溶剤を単にこの分野の溶剤として公知の上記のご
ときアルキルベンゼンに変換して反応せしめると、得ら
れる銅フタロシアニンの色調が不鮮明で実用できない。If a conventional solvent is simply converted into the above-mentioned alkylbenzene, which is known as a solvent in this field, and reacted, the color tone of the resulting copper phthalocyanine will be indistinct and cannot be put to practical use.

タロシアニン顔料が得られることを発見した。The present inventors conducted research on alkylbenzenes with various structures in order to synthesize crude copper phthalocyanine with a vivid color tone. As a result, the inventors conducted a reaction in an alkylbenzene solvent with a specific structure, and found that conventional solvents could be It was discovered that a copper phthalocyanine pigment with a clearer color tone than the crude phthalocyanine synthesized using the method was obtained.
すなわち本発明は、前記の二) IJル溶剤法、フタル
酸溶剤法において、溶剤として下記一般式のアルキルベ
ンゼンを使用し、反応せしめるものである。That is, the present invention uses an alkylbenzene of the following general formula as a solvent in the above-mentioned 2) IJ solvent method and phthalic acid solvent method to carry out the reaction.

顔料を得るもので、実用上の価値犬なものである。According to the present invention, the general formula (R in the formula represents an alkyl group having 3 carbon atoms) is useful for improving environmental hygiene and preventing pollution in workplaces where harmless alkylbenzene is used as a solvent. This method yields a copper phthalo-7-anine pigment with better color tone than the standard, and is of great practical value.

本発明は無害のアルキルベンゼンを溶剤として使用し、

。また反応は、必要があれば加圧して行なってもよい。The present invention uses harmless alkylbenzene as a solvent,
The amount of solvent used for the reaction may be the same as in the conventional method. Further, the reaction may be carried out under pressure if necessary.

ギー損失を低減できるので好ましい。The degree of pressurization is effective from a pressure of about 2 ky/cm2, and good results are obtained with a pressure of 3 kg/6n2 or more, but in practice it is carried out at a pressure of about 1.0 ky/cm2. The pressurization method utilizes the pressure of gas and steam generated by heating and reacting in a closed container such as an autoclave. The reactor is provided with an adjustable gas outlet through which a portion of the gas or vapor is released to adjust the pressure in the reactor. It is preferable to carry out the reaction under pressure because it suppresses the decomposition of ureas, increases the yield of copper phthalonanine, and reduces thermal energy loss.

Filtration, washing with water, and drying at 90°C to 100°C yielded 53 parts of copper phthalocyanine pigment.This product had a clear blue color, which was brighter than that obtained by the conventional solvent method. The comparison is shown next. The product used for comparison was one in which nitrobenzene, inglobiltoluene, diisozolopyltoluene, and isopropylxylene were used as solvents, and other conditions were the same as in this example (ie, conventional method). Each sample was prepared by mixing 1 part of phthalocyanine pigment and 10 parts of titanium white R-820 with 17 parts of alkyd varnish having a non-volatile content of 60 parts, and the resulting paint was spread and measured.
