本発明は、アルキルナフタレンホルムアルデヒド重合体の精製方法、特に、金属含有量の低減されたアルキルナフタレンホルムアルデヒド重合体の工業的に有利な精製方法に関する。 The present invention relates to a method for purifying an alkylnaphthalene formaldehyde polymer, and more particularly to an industrially advantageous method for purifying an alkylnaphthalene formaldehyde polymer having a reduced metal content.
モノメチルナフタレン及び/又はジメチルナフタレンを主成分とする多環式芳香族炭化水素とパラホルムアルデヒドとを、芳香族モノスルホン酸の存在下に反応させて得られる芳香族炭化水素樹脂は公知であり、得られる樹脂は、液状エポキシ樹脂との相溶性及びキシレンに対する溶解性が優れている(特許文献1参照)。 Aromatic hydrocarbon resins obtained by reacting polycyclic aromatic hydrocarbons mainly composed of monomethylnaphthalene and / or dimethylnaphthalene with paraformaldehyde in the presence of aromatic monosulfonic acid are known and obtained. The obtained resin is excellent in compatibility with a liquid epoxy resin and in xylene (see Patent Document 1).
また、メトキシメチレンナフタレン化合物と、フェノール、クレゾール又はナフトール等のフェノール性水酸基を有する化合物とを、ジエチル硫酸の存在下に反応させ、ナフタレンとフェノール性水酸基を有する化合物とがメチレン基を介して結合した構造を持つフェノール樹脂を得る方法が公知である(特許文献2参照)。 Further, a methoxymethylene naphthalene compound and a compound having a phenolic hydroxyl group such as phenol, cresol or naphthol were reacted in the presence of diethyl sulfate, and the naphthalene and the compound having a phenolic hydroxyl group were bonded via a methylene group. A method for obtaining a phenol resin having a structure is known (see Patent Document 2).
これらの樹脂は半導体用のコーティング剤、レジスト用樹脂、半導体下層膜形成樹脂として使用されている。これらの用途においては、特に金属含有量が、歩留まり向上のために重要な性能項目となっている。すなわち、金属含有量の多い樹脂を用いた場合には、半導体中に金属が残存し、半導体の電気特性を低下させることから、金属含有量を低減することが求められている。 These resins are used as semiconductor coating agents, resist resins, and semiconductor underlayer film forming resins. In these applications, particularly the metal content is an important performance item for improving the yield. That is, when a resin having a high metal content is used, the metal remains in the semiconductor, which lowers the electrical characteristics of the semiconductor. Therefore, it is required to reduce the metal content.
金属含有量の低減されたアルキルナフタレンホルムアルデヒド重合体の製造方法として、アルキルナフタレンホルムアルデヒド重合体と有機溶媒を含む溶液を、イオン交換樹脂と接触させる方法や、フィルターで濾過する方法等が考えられる。
しかしながら、イオン交換樹脂を用いる方法では、種々の金属イオンを含有する場合は、イオン交換樹脂の選択に難があり、金属の種類によっては除去が困難であるという問題、非イオン性の金属の除去が困難であるという問題、さらには、ランニングコストが大きいという問題がある。一方、フィルターで濾過する方法では、イオン性金属の除去が困難であるという問題がある。
そのため、金属含有量の低減されたアルキルナフタレンホルムアルデヒド重合体の工業的に有利な精製方法の確立が望まれている。As a method for producing an alkylnaphthalene formaldehyde polymer with a reduced metal content, a method of bringing a solution containing an alkylnaphthalene formaldehyde polymer and an organic solvent into contact with an ion exchange resin, a method of filtering with a filter, or the like can be considered.
However, in the method using an ion exchange resin, when various kinds of metal ions are contained, it is difficult to select an ion exchange resin, and it is difficult to remove depending on the type of metal, and removal of nonionic metals. Is difficult, and there is a problem that running cost is high. On the other hand, the method of filtering with a filter has a problem that it is difficult to remove the ionic metal.
Therefore, it is desired to establish an industrially advantageous purification method for alkylnaphthalene formaldehyde polymers having a reduced metal content.
本発明の目的は、金属含有量の低減されたアルキルナフタレンホルムアルデヒド重合体の工業的に有利な精製方法を提供することにある。 An object of the present invention is to provide an industrially advantageous purification method for alkylnaphthalene formaldehyde polymers having a reduced metal content.
本発明者らは上記課題を解決するため鋭意検討した結果、アルキルナフタレンホルムアルデヒド重合体と有機溶媒を含む溶液を、酸性の水溶液と接触させることにより、種々の金属の含有量が著しく低下することを見出し、本発明に到った。 As a result of intensive studies to solve the above problems, the present inventors have found that the content of various metals is significantly reduced by bringing a solution containing an alkylnaphthalene formaldehyde polymer and an organic solvent into contact with an acidic aqueous solution. The headline and the present invention were reached.

本発明により、種々の金属の含有量の著しく低減されたアルキルナフタレンホルムアルデヒド重合体の精製方法を提供できる。 According to the present invention, it is possible to provide a method for purifying an alkylnaphthalene formaldehyde polymer in which the content of various metals is significantly reduced.
以下、本発明を詳細に説明する。
本発明は、アルキルナフタレンホルムアルデヒド重合体を有機溶媒に溶解させ、その溶液を酸性水溶液と接触させることにより、アルキルナフタレンホルムアルデヒド重合体と有機溶媒を含む溶液に含まれていた金属分を水相に移行させ、金属含有量の低減されたアルキルナフタレンホルムアルデヒド重合体を精製する。Hereinafter, the present invention will be described in detail.

Further, in obtaining the polymer, for example, after reacting alkylnaphthalene and formaldehyde, it is modified with phenol, a phenol derivative, naphthol, a naphthol derivative, or the like to obtain a desired polymer. A polymer finally obtained through a reaction may be used.
本発明に用いる重合体を得るのに用いられるアルキルナフタレンとしては、α―メチルナフタレン、β―メチルナフタレン、1,2−ジメチルナフタレン、1,3−ジメチルナフタレン、1,4−ジメチルナフタレン、1,5−ジメチルナフタレン、1,6−ジメチルナフタレン、1,7−ジメチルナフタレン、1,8−ジメチルナフタレン、2,3−ジメチルナフタレン、2,6−ジメチルナフタレン、2,7−ジメチルナフタレン、トリメチルナフタレン、テトラメチルナフタレン、アセナフテン、メチルアセナフテン、シクロヘキシルナフタレン、ノルボルニルナフタレン、トリシクロデカニルナフタレン、アダマンチルナフタレン、デカニルナフタレン及びビシクロオクチルナフタレンの群から選ばれる1種、又は2種以上の混合物である。原料調達の優位性と樹脂製造のしやすさ、光学特性等を総合的に考慮した際には1,5−、2,6−、2,7−、1,8−ジメチルナフタレンないしアセナフテンが好ましく、その中でも1,5−ジメチルナフタレンが特に好ましい。 Examples of the alkylnaphthalene used for obtaining the polymer used in the present invention include α-methylnaphthalene, β-methylnaphthalene, 1,2-dimethylnaphthalene, 1,3-dimethylnaphthalene, 1,4-dimethylnaphthalene, 1, 5-dimethylnaphthalene, 1,6-dimethylnaphthalene, 1,7-dimethylnaphthalene, 1,8-dimethylnaphthalene, 2,3-dimethylnaphthalene, 2,6-dimethylnaphthalene, 2,7-dimethylnaphthalene, trimethylnaphthalene, One or a mixture of two or more selected from the group consisting of tetramethylnaphthalene, acenaphthene, methylacenaphthene, cyclohexylnaphthalene, norbornylnaphthalene, tricyclodecanylnaphthalene, adamantylnaphthalene, decanylnaphthalene and bicyclooctylnaphthalene is there. 1,5-, 2,6-, 2,7-, 1,8-dimethylnaphthalene or acenaphthene is preferred when comprehensively considering the superiority of raw material procurement, ease of resin production, optical properties, etc. Of these, 1,5-dimethylnaphthalene is particularly preferable.

For example, an aqueous solution in which a mineral acid such as hydrochloric acid, sulfuric acid, nitric acid or phosphoric acid is dissolved in water, or acetic acid, propionic acid, succinic acid, malonic acid, succinic acid, fumaric acid, maleic acid, tartaric acid, citric acid, methanesulfone An aqueous solution in which an organic acid such as acid, phenolsulfonic acid, p-toluenesulfonic acid, trifluoroacetic acid or the like is dissolved in water can be used.

Among these acidic aqueous solutions, aqueous solutions of sulfuric acid, nitric acid, and carboxylic acids such as acetic acid, succinic acid, tartaric acid, and citric acid are preferable, and aqueous solutions of sulfuric acid, succinic acid, tartaric acid, and citric acid are preferable, and an aqueous solution of succinic acid is particularly preferable. . Since polyvalent carboxylic acids such as succinic acid, tartaric acid, and citric acid are coordinated to metal ions to produce a chelate effect, it is considered that the metal can be removed more. Moreover, the water used here is preferably one having a low metal content, such as ion-exchanged water, for the purpose of the present invention.
本発明で使用する酸性の水溶液のpHは特に制限されないが、水溶液の酸性度があまり大きくなるとアルキルナフタレンホルムアルデヒド樹脂に悪影響を及ぼすことがあり好ましくない。通常、pH範囲は0〜5程度であり、より好ましくはpH0〜3程度である。 The pH of the acidic aqueous solution used in the present invention is not particularly limited, but if the acidity of the aqueous solution becomes too large, it may adversely affect the alkylnaphthalene formaldehyde resin, which is not preferable. Usually, the pH range is about 0 to 5, more preferably about pH 0 to 3.

本発明は、上記のような酸性の水溶液と、アルキルナフタレンホルムアルデヒド樹脂及び有機溶媒を含む溶液とを接触させることにより、金属分を抽出することを特徴とする。
抽出処理を行う際の温度は通常、20〜90℃であり、好ましくは30〜80℃の範囲である。抽出操作は、例えば、攪拌等により、よく混合させたあと、静置することにより行われる。これにより、アルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液に含まれていた金属分が水相に移行する。The present invention is characterized in that a metal component is extracted by bringing an acidic aqueous solution as described above into contact with a solution containing an alkylnaphthalene formaldehyde resin and an organic solvent.
The temperature at the time of performing the extraction treatment is usually 20 to 90 ° C, and preferably 30 to 80 ° C. The extraction operation is performed, for example, by mixing the mixture well by stirring or the like and then allowing it to stand. Thereby, the metal content contained in the solution containing the alkylnaphthalene formaldehyde resin and the organic solvent is transferred to the aqueous phase.
得られる混合物は、アルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液相と水相に分離するのでデカンテーション等によりアルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液を回収する。静置する時間は特に制限されないが、静置する時間があまりに短いと有機溶媒を含む溶液相と水相との分離が悪くなり好ましくない。通常、静置する時間は10分以上であり、より好ましくは30分以上である。
また、抽出処理は1回だけでもかまわないが、混合、静置、分離という操作を複数回繰り返して行うのも有効である。Since the resulting mixture is separated into a solution phase containing an alkylnaphthalene formaldehyde resin and an organic solvent and an aqueous phase, a solution containing the alkylnaphthalene formaldehyde resin and the organic solvent is recovered by decantation or the like. The standing time is not particularly limited. However, if the standing time is too short, the separation between the solution phase containing the organic solvent and the aqueous phase is not preferable. Usually, the time to stand still is 10 minutes or more, More preferably, it is 30 minutes or more.
The extraction process may be performed only once, but it is also effective to repeat the operations of mixing, standing, and separation a plurality of times.
酸性の水溶液を用いてこのような抽出処理を行った場合は、処理を行ったあとに、該水溶液から抽出し、回収したアルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液は、さらに水との抽出処理を行うことが好ましい。抽出操作は、攪拌等により、よく混合させたあと、静置することにより行われる。そして得られる溶液は、アルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液相と水相に分離するのでデカンテーション等によりアルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液相を回収する。また、ここで用いる水は、本発明の目的に沿って、金属含有量の少ないもの、例えばイオン交換水等が好ましい。抽出処理は1回だけでもかまわないが、混合、静置、分離という操作を複数回繰り返して行うのも有効である。また、抽出処理における両者の使用割合や、温度、時間等の条件は特に制限されないが、先の酸性の水溶液との接触処理の場合と同様で構わない。 When such an extraction process is performed using an acidic aqueous solution, the solution containing the extracted alkylnaphthalene formaldehyde resin and the organic solvent extracted from the aqueous solution after the process is further extracted with water. It is preferable to carry out. The extraction operation is performed by allowing the mixture to stand after mixing well by stirring or the like. The obtained solution is separated into a solution phase containing an alkylnaphthalene formaldehyde resin and an organic solvent and an aqueous phase, and therefore a solution phase containing the alkylnaphthalene formaldehyde resin and the organic solvent is recovered by decantation or the like. Moreover, the water used here is preferably one having a low metal content, such as ion-exchanged water, for the purpose of the present invention. The extraction process may be performed only once, but it is also effective to repeat the operations of mixing, standing, and separation a plurality of times. In addition, the use ratio of both in the extraction process, conditions such as temperature and time are not particularly limited, but may be the same as in the case of the contact process with the acidic aqueous solution.
こうして得られたアルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液に混入する水分は減圧蒸留等の操作を施すことにより容易に除去できる。また、必要により有機溶媒を加え、アルキルナフタレンホルムアルデヒド樹脂の濃度を任意の濃度に調整することができる。 Water contained in the solution containing the alkylnaphthalene formaldehyde resin thus obtained and the organic solvent can be easily removed by performing an operation such as vacuum distillation. Moreover, an organic solvent can be added as needed, and the density | concentration of alkyl naphthalene formaldehyde resin can be adjusted to arbitrary density | concentrations.
得られたアルキルナフタレンホルムアルデヒド樹脂と有機溶媒を含む溶液から、アルキルナフタレンホルムアルデヒド樹脂のみ得る方法は、減圧除去や再沈殿による分離、及びそれらの組み合わせ等、公知の方法で行うことができる。 A method for obtaining only the alkylnaphthalene formaldehyde resin from the solution containing the obtained alkylnaphthalene formaldehyde resin and an organic solvent can be performed by a known method such as separation under reduced pressure, separation by reprecipitation, or a combination thereof.
