Abstract
Description
本願は、2018年8月20日に、日本に出願された特願2018-154145号に基づき優先権を主張し、その内容をここに援用する。
特許文献7には、ダイマージオールとポリイソシアネートとを反応させて得た生成物に、MOIなどの不飽和イソシアネート化合物を反応させて合成したウレタンアクリレートが記載されている。また、特許文献7には、このウレタンアクリレートを含む硬化性組成物が記載されている。
MOIは、イソプロペニルオキサゾリンまたは2-アミノエチルメタクリレート塩酸塩と、ホスゲンとの反応により合成されている。AOIは、2-ビニルオキサゾリンまたは2-アミノエチルアクリレート塩酸塩と、ホスゲンとの反応により合成されている。MAIは、メタクリル酸アミドとオキザリルクロリドとの反応により合成されている。
また、従来の不飽和イソシアネート化合物は、従来の判定方法では品質に大きな差が見られなくても、これを用いて不飽和化合物を製造した場合、製造中に急激に反応生成物の粘度が上昇したり、ゲル化したりする場合があった。このため、利用時の安定性を向上させることが要求されていた。
しかし、不飽和イソシアネート化合物に多くの重合防止剤を添加すると、これを原料として不飽和化合物を製造した場合に、不飽和化合物とともに、重合防止剤に起因する着色成分が生成されやすくなる(例えば、非特許文献1参照)。このため、製造した不飽和化合物が、着色されてしまう場合があった。
すなわち、本発明は以下の事項に関する。
前記化合物(A)100質量部に対して、前記化合物(B)を0.00002~0.2質量部含有することを特徴とする組成物。
(R1-COO)n-R2-(R3-R1)m …(2)
(一般式(1)および一般式(2)において、R1は炭素数2~7のエチレン性不飽和基である。R2は炭素数1~7のm+n価の炭化水素基であり、エーテル基を含んでいてもよい。一般式(1)のR1およびR2と一般式(2)のR1およびR2はそれぞれ同じである。一般式(2)において、R3は、-NHC(=O)-である。nおよびmは1または2の整数である。)
[3] 前記組成物中の前記化合物(A)の含有量が95.0質量%以上である、[1]または[2]に記載の組成物。
一般式(1)で示される化合物(A)と、一般式(2)で示される化合物(B)とを含み、前記化合物(A)100質量部に対して前記化合物(B)を0.2質量部超の量で含有する混合物を製造する工程と、

(R1-COO)n-R2-(R3-R1)m …(2)
(一般式(1)および一般式(2)において、R1は炭素数2~7のエチレン性不飽和基である。R2は炭素数1~7のm+n価の価炭化水素基であり、エーテル基を含んでいてもよい。一般式(1)のR1およびR2と一般式(2)のR1およびR2はそれぞれ同じである。一般式(2)において、R3は、-NHC(=O)-である。nおよびmは1または2の整数である。)
[5] 前記精製工程によって得られた組成物において、
前記化合物(A)100質量部に対する前記化合物(B)の含有量が0.00002~0.2質量部であることを特徴とする、[4]に記載の組成物の製造方法。
[8]前記反応生成物が、不飽和ウレタン化合物、不飽和チオウレタン化合物、不飽和ウレア化合物、または不飽和アミド化合物である[6]または[7]に記載の不飽和化合物の製造方法。
また、本発明の組成物は、化合物(A)100質量部に対して、化合物(B)を0.00002質量部以上含有するため、不飽和化合物を高い収率で製造できる。
なお、以下の例は、発明の趣旨をより良く理解させるために具体的に説明するものであり、特に指定のない限り、本発明をこれらのみに限定するものではない。本発明の範囲内において、必要に応じて、量や種類や比率や数や位置などについて、省略、変更、交換、及び/又は追加することも可能である。
また本明細書に記載の圧力は、絶対圧力である。
本実施形態の組成物は、不飽和イソシアネート化合物を含有するものである。本実施形態の組成物は、一般式(1)で示される化合物(A)と、上記特定化合物である一般式(2)で示される化合物(B)とを含む。本実施形態の組成物は、化合物(A)100質量部に対して、化合物(B)を0.00002~0.2質量部含有する。また、本実施形態の組成物は、組成物中の化合物(A)の含有量が95.0質量%以上であることが好ましい。
(R1-COO)n-R2-(R3-R1)m …(2)
一般式(1)および一般式(2)において、nおよびmは1または2の整数であり、合成のしやすさから、いずれも1であることが好ましい。
添加物としては、例えば、ハイドロキノン等の重合防止剤が挙げられる。
本実施形態の組成物は、気相部に露点-30℃以下の乾燥窒素ガスが充填された容器内に収容されていることが好ましい。このことにより、蒸留後の組成物中の化合物(A)と水分との接触が防止され、組成物中での化合物(B)の増加が抑制される。その結果、保管時の安定性および利用時の安定性の良好となる。
本実施形態の組成物の製造方法は、一般式(1)で示される化合物(A)と、一般式(2)で示される化合物(B)とを含み、化合物(A)100質量部に対して化合物(B)を0.2質量部超含有する混合物を製造する工程と、混合物を2.0~4.0の還流比、1.0~10.0kPaの圧力、90~140℃の蒸留温度で蒸留法により精製して、化合物(A)100質量部に対する化合物(B)の含有量が0.00002~0.2質量部である精製物を得る精製工程とを含む。また、前記精製工程において、上記の蒸留法により精製して、化合物(A)の含有量が95.0質量%以上であり、化合物(A)100質量部に対する化合物(B)の含有量が0.00002~0.2質量部である精製物を得る精製工程であることが好ましい。
化合物(A)と化合物(B)とを含み、化合物(A)100質量部に対して、化合物(B)を0.2質量部超含有する混合物を製造する方法としては、例えば、従来公知の化合物(A)の製造方法を用いて、化合物(A)を生成させると同時に化合物(B)を副生させる方法が挙げられる。
具体的には、例えば、不飽和カルボン酸クロリドとアミノアルコール塩酸塩との反応によって、不飽和カルボン酸アミノアルキルエステル塩酸塩を合成する。次いで、不飽和カルボン酸アミノアルキルエステル塩酸塩と塩化カルボニルとを反応させることにより、化合物(A)である不飽和カルボン酸イソシアナトアルキルエステルを生成させる。それと同時に、化合物(A)のイソシアナト基(-NCO)の一部が、-NHC(=O)-R1(R1は不飽和カルボン酸イソシアナトアルキルエステルを形成しているエチレン性不飽和基と同じ基である。)で置換された不純物である化合物(B)を副生させる方法等が挙げられる。
このようにして得られた化合物(A)と化合物(B)との混合物中には、一般的に、化合物(A)100質量部に対して、化合物(B)が0.2質量部超含まれている。
本実施形態においては、このようにして得られた化合物(A)と化合物(B)とを含む混合物を、還流比(還流量/留出量)2.0~4.0、圧力1.0~10.0kPa、蒸留温度90~140℃で蒸留法により精製し、化合物(A)を低沸成分として回収する。このことにより、化合物(A)100質量部に対する前記化合物(B)の含有量が0.00002~0.2質量部である精製物(組成物)を得る。化合物(A)は、通常は液体であるので溶媒は不要である。
混合物に添加した重合防止剤は、蒸留を行うことにより一部除去される。蒸留後に組成物中に残留する重合防止剤は、組成物の保管中および輸送中に組成物がゲル化することを防止し、組成物の保管時の安定性の向上に寄与する。重合防止剤は、必要に応じて、蒸留後に得られた組成物に添加してもよい。
本実施形態の不飽和化合物の製造方法は、上記の組成物と、活性水素を有する化合物とを混合し、組成物に含まれる化合物(A)と活性水素を有する化合物とを反応させて反応生成物を得る工程を含む。
また、活性水素を有する化合物における活性水素は、窒素原子、酸素原子、硫黄原子等に結合した水素原子であり、炭素原子に結合した水素原子と比較して高い反応性を示す。活性水素を有する化合物は、特に限定されるものではなく、不飽和化合物の構造に応じて適宜選択できる。
例えば、活性水素を有する化合物として、水酸基、メルカプト基、アミノ基(環状アミン、アミド、イミドを含む)、カルボキシ基等の活性水素含有基を有する化合物を用いた場合、以下に示す反応により、以下に示す反応生成物(不飽和化合物)が得られる。
組成物に含まれる化合物(A)とメルカプト基を有する化合物とを反応させると、化合物(A)のイソシアナト基とメルカプト基とが反応して、不飽和チオウレタン化合物が生成する。本実施形態において、不飽和チオウレタン化合物は、分子内にエチレン性不飽和結合およびチオウレタン結合を含む化合物を意味する。
組成物に含まれる化合物(A)とカルボキシ基を有する化合物とを反応させると、化合物(A)のイソシアナト基とカルボキシ基とが反応して、不飽和アミド化合物が生成する。本実施形態において、不飽和アミド化合物は、分子内にエチレン性不飽和結合およびアミド結合を含む化合物を意味する。
水酸基を有する化合物としては、上記の中でも、ポリオールが好ましく、脂肪族ポリオールがより好ましい。
メルカプト基を有する化合物としては、上記の中でも、ポリチオールが好ましく、脂肪族ポリチオールがより好ましい。
アミノ基を有する化合物としては、上記の中でも、ポリアミンが好ましく、脂肪族ポリアミンがより好ましい。
カルボキシ基を有する化合物としては、上記の中でも、ポリカルボン酸が好ましく、脂肪族・芳香族ポリカルボン酸がより好ましい。
活性水素を有する化合物としては、上記の中でも、汎用性の点で、ポリオール、ポリチオール、ポリアミンまたはポリカルボン酸であることが好ましく、ポリオールが特に好ましい。
イソシアナト基/活性水素の比は、従来、化合物(A)と活性水素を有する化合物との反応において適用されている比と同じであってよい。イソシアナト基/活性水素の比は、活性水素を有する化合物の種類によって異なる。
反応触媒としては、公知の反応触媒を用いることができる。反応触媒の具体例としては、ジブチル錫ジラウレート、ナフテン酸銅、ナフテン酸コバルト、ナフテン酸亜鉛、トリエチルアミン、1,4-ジアザビシクロ[2.2.2]オクタン、ジルコニウムアセチルアセトナート、チタンジイソプロポキシビス(エチルアセトアセテート)、ビスマストリス(2-エチルヘキサノアート)と2-エチルヘキサン酸の混合物、等が挙げられる。これらの反応触媒は、1種単独で用いてもよいし、2種以上を組み合わせて用いてもよい。
その他、前記反応に際し、目的に応じて、公知の光安定剤、紫外線吸収剤、酸化防止剤、染料充填剤、反応性希釈剤等の種々の物質を添加してもよい。
また、本実施形態の組成物は、化合物(A)100質量部に対して、化合物(B)を0.00002質量部以上含有するため、高い収率で製造できる。

50gの混合物2を、表3および表4に示す条件(還流比(還流量/留出量)、蒸留温度、蒸留圧力)で蒸留し、実施例7~12、比較例5~8の液状の組成物を得た。
組成物を下記の条件でガスクロマトグラフィー(GC)分析することにより行った。
カラム:DB-1、注入口温度:300℃、検出温度:300℃
カラム温度:50℃→(10℃/min)→300℃
カラム流量:1.4ml/min
スプリット比:1/50
検出器:FID
収率=(組成物質量/理論収量)×100(%)
実施例1~12、比較例1~8の蒸留直後の液状の組成物100gを、透明なガラス容器に入れ、密封状態で、25℃で30日間保管し、保管後の外観を以下に示す方法により評価した。
組成物を入れた透明なガラス容器を、約45度の角度に数回傾け、目視により以下に示す規準で評価した。その結果を表1~表4に示す。
「基準」
変化なし:ガラス容器を傾けてから30秒未満で流れ落ちる。
水飴状:ガラス容器を傾けてから30秒以上180秒未満で流れ落ちる。
固化:ガラス容器を傾けてから180秒以上経過しても流動しない。
密封状態で、25℃で30日間保管した実施例1~12、比較例1~8の組成物の粘度を、JIS―Z 8803:2011に則り以下に示す方法により求めた。その結果を表1~表4に示す。
各組成物について、ウベローデ式粘度計を用いて25℃での動粘度(cm3/sec)を測定した。実施例1~6、比較例1~4については、動粘度の測定値に以下に示すカレンズMOI(登録商標)(昭和電工製)の密度を乗じて粘度(mPa・sec)を算出した。また、実施例7~12、比較例5~8については、動粘度の測定値に以下に示すカレンズAOI(登録商標)(昭和電工製)の密度を乗じて粘度(mPa・sec)を算出した。
(カレンズMOI(登録商標)の密度)1.096g/cm3(25℃)

これに対し、化合物(A)100質量部に対する化合物(B)の含有量が0.2質量部超含まれている比較例1~8の組成物では、25℃で30日間の保管することにより粘度が高くなりすぎて、粘度の測定ができなかった。また、比較例1~8の組成物では、外観評価が「水飴状」または「固化」となった。
