Description
本発明は、ポリアミドやポリイミドの原料として有用な９，９−ビス（アミノアルキル）フルオレン化合物の経済的な製造方法に関する。 The present invention relates to an economical method for producing a 9,9-bis (aminoalkyl) fluorene compound useful as a raw material for polyamide and polyimide.
９，９−ビス（アミノアルキル）フルオレン化合物は、自由体積を大きくするカルド骨格を有しており、特異な性質を有するポリアミドやポリイミドの原料として期待されている。従来、この９，９−ビス（アミノアルキル）フルオレン化合物の具体的な製造例としては、９，９−ビス（シアノエチル）フルオレンを、エタノール中、スポンジ（ラネー）ニッケル触媒の存在下で水素化して９，９−ビス（アミノプロピル）フルオレンを製造する方法が知られている（特許文献１）。この文献においては、目的物の収率や品質に関する記載はないが、蒸留精製した後も粘性ある液体として得られているところから、副生物である不純物をかなり含むものと考えられる。同じく９，９−ビス（シアノエチル）フルオレンを、アンモニアを含有するイソプロパノールやトルエン中、ケイ酸ナトリウムと酸化コバルトの混合物を水素還元することによって得られる触媒の存在下で水素化する方法も知られている（特許文献２、３）。この文献においては、目的物と共に、ニトリル基の一方のみが水素化されたアミノニトリルを含めた収率が記載されており、また反応時間が非常に長いところから、この方法では、短時間で二つのニトリル基を完全に水素化することは困難であると想定される。 The 9,9-bis (aminoalkyl) fluorene compound has a cardo skeleton that increases the free volume, and is expected as a raw material for polyamide and polyimide having unique properties. Conventionally, as a specific production example of the 9,9-bis (aminoalkyl) fluorene compound, 9,9-bis (cyanoethyl) fluorene is hydrogenated in ethanol in the presence of a sponge (Raney) nickel catalyst. A method for producing 9,9-bis (aminopropyl) fluorene is known (Patent Document 1). Although there is no description regarding the yield and quality of the target product in this document, it is considered that the product contains a substantial amount of impurities as a by-product because it is obtained as a viscous liquid after distillation purification. Also known is a method of hydrogenating 9,9-bis (cyanoethyl) fluorene in the presence of a catalyst obtained by hydrogen reduction of a mixture of sodium silicate and cobalt oxide in isopropanol or toluene containing ammonia. (Patent Documents 2 and 3). In this document, the yield including the target product and an aminonitrile in which only one of the nitrile groups is hydrogenated is described, and the reaction time is very long. It is assumed that it is difficult to completely hydrogenate two nitrile groups.
そこで本発明の目的は、９，９−ビス（シアノアルキル）フルオレン化合物を水素化することによって、相当する９，９−ビス（アミノアルキル）フルオレン化合物を、短時間の反応で収率よく製造する方法を提供することにある。 Accordingly, an object of the present invention is to produce a corresponding 9,9-bis (aminoalkyl) fluorene compound in a high yield with a short reaction time by hydrogenating the 9,9-bis (cyanoalkyl) fluorene compound. It is to provide a method.

Is to be manufactured. Examples of the alcohol that can be used as the solvent include methanol, ethanol, isopropanol, n-propanol, and the like, and methanol is most preferable. The preferred amount of alcohol used is 0.5 to 20 parts by weight, preferably 1 to 10 parts by weight, particularly preferably 2 to 8 parts by weight, based on 1 part by weight of the 9,9-bis (cyanoalkyl) fluorene compound. is there. Ammonia is preferably used in a proportion of 2 to 20 mol, particularly 2.5 to 10 mol, per mol of 9,9-bis (cyanoalkyl) fluorene compound.
本発明において触媒として使用されるスポンジコバルト触媒は、コバルトと、溶出される金属、例えばアルミニウム、珪素、亜鉛、錫等との合金から、侵食剤例えばアルカリ、酸などによって溶出される金属を溶出させて得られるスポンジ状形態の活性コバルトを主成分とする触媒である。スポンジコバルト触媒は、９，９−ビス（シアノアルキル）フルオレン化合物１質量部に対し、０．０１〜０．５質量部、好ましくは０．０５〜０．４質量部、とくに好ましくは０．１〜０．３質量部となる割合で使用するのが好ましい。 The sponge cobalt catalyst used as a catalyst in the present invention elutes metal eluted by an eroding agent such as an alkali or acid from an alloy of cobalt and an eluted metal such as aluminum, silicon, zinc or tin.

９，９−ビス（シアノアルキル）フルオレン化合物の水素化反応は、種々の方法によって行うことができる。例えば、耐圧反応釜に、アルコール、アンモニア、スポンジコバルト触媒及び９，９−ビス（シアノアルキル）フルオレン化合物を仕込み、所定温度まで昇温後、水素を導入することによって行うことができる。水素化は、通常、７０〜１５０℃、好ましくは９０〜１３０℃の温度で行われる。反応温度が低すぎると充分な反応速度を得ることができず、また反応温度が高くなり過ぎると、副反応や分解反応を伴いやすくなり、収率が低下する傾向が見られる。また反応圧力は、水素分圧で、通常、０．５〜３０ＭＰａ、好ましくは２〜２０ＭＰａである。反応時間は、触媒の使用量や反応温度、その他反応条件によっても異なるが、通常、０．５〜３０時間、工業的観点からは１〜２０時間の範囲であり、このような反応時間で反応が完結するように反応条件の設定をすることが好ましい。 The hydrogenation reaction of the 9,9-bis (cyanoalkyl) fluorene compound can be performed by various methods. For example, it can be carried out by charging alcohol, ammonia, a sponge cobalt catalyst and a 9,9-bis (cyanoalkyl) fluorene compound into a pressure-resistant reaction kettle, raising the temperature to a predetermined temperature, and then introducing hydrogen. The hydrogenation is usually performed at a temperature of 70 to 150 ° C, preferably 90 to 130 ° C. If the reaction temperature is too low, a sufficient reaction rate cannot be obtained, and if the reaction temperature is too high, side reactions and decomposition reactions tend to occur and the yield tends to decrease. The reaction pressure is a hydrogen partial pressure and is usually 0.5 to 30 MPa, preferably 2 to 20 MPa. The reaction time varies depending on the amount of catalyst used, reaction temperature, and other reaction conditions, but is usually 0.5 to 30 hours, and 1 to 20 hours from an industrial point of view. It is preferable to set reaction conditions so that is completed.
反応終了後は、常法によって目的とする９，９−ビス（アミノアルキル）フルオレン化合物を単離することができる。例えば、反応液を冷却後、反応釜から取り出し、濾別によってスポンジコバルト触媒を除き、濾液を濃縮してアンモニアや溶媒のアルコールを回収すると共に、残渣として粗製の９，９−ビス（アミノアルキル）フルオレン化合物を単離することができる。必要に応じ、これを蒸留、晶析、再結晶などに付することによって精製することができる。 After completion of the reaction, the desired 9,9-bis (aminoalkyl) fluorene compound can be isolated by a conventional method. For example, after cooling the reaction solution, it is taken out from the reaction kettle, the sponge cobalt catalyst is removed by filtration, the filtrate is concentrated to recover ammonia and alcohol as a solvent, and crude 9,9-bis (aminoalkyl) as a residue. Fluorene compounds can be isolated. If necessary, it can be purified by subjecting it to distillation, crystallization, recrystallization and the like.
