Abstract
Description
[2]一般式(1)で示されるアミン化合物のうち、R1、R2、R3及びR4が水素原子であることを特徴とする上記[1]に記載の触媒組成物。
2Lのセパラブルフラスコに、ピペラジン43.1g(0.5mol)、トリエチルアミン151.8g(1.5mol)を仕込み、トルエンで希釈した。窒素置換後、これにトルエンで希釈した2,3−ジブロモプロピオン酸エチル(東京化成工業社製)を攪拌しながら添加し、100℃で24時間熟成反応を行った。析出したトリエチルアミンの臭化水素塩をろ過により除去し、得られた反応液を濃縮し、エステル体を合成した。このエステル体をテトロヒドロフランに溶解させ、氷浴下、水素化アルミニウムリチウムのテトロヒドロフラン溶液に攪拌しながら添加した。室温で2時間反応後、水、15%水酸化ナトリウム水溶液を加えて反応を停止し、不溶物をろ過により除去した。反応液を濃縮後、酢酸エチルで抽出洗浄した。酢酸エチルを除去し、目的化合物である1,4−ジアザビシクロ[2.2.2]オクタン−2−メタノール(以下、「例示化合物1」と称する)を48g得た(収率68%)。
表1に示す配合比にて、アミン化合物をグリコール類等で希釈した触媒1〜13を調合した。
・クリームタイム:
発泡開始時間、フォームが上昇開始する時間を目視にて測定した。
反応が進行し、液状物質から樹脂状物質に変わる時間を測定した。
フォームの上昇が停止する時間をレーザ変位センサ(キーエンス社製、型式:LF−2510)を用いて測定した。
・全体密度:
成型フォームの重量を測定し、体積で除した。
ISO2439Bに則って実施した。成型フォームをクラッシング(75%で3回)した後、25%、又は65%に圧縮するのに要する荷重を測定した。
直径16mm、質量16gの鋼球を470mmの高さから成型フォームに落下させ、跳ね返った最高の高さを記録する。反発弾性を以下の式により計算した。
C:鋼球を落下させる高さ(mm)
D:跳ね返った最高の高さ(mm)。
成型フォームの中心部から20×20×5cmをカットし、コア部分とする。コア部分の重量を測定し、体積で除した。
ISO3386/1に則って実施した。上記コア部分をクラッシング(75%で3回)した後、40%に圧縮するのに要する荷重を測定した。
成型フォームの中心部から5×5×3cm寸法のフォームをカットし、900mLのマヨネーズ瓶の中に入れ蓋をした。この瓶を80℃で1時間加熱後室温に戻し、5人のモニターがそのフォームの臭いをかぎ、臭いの強さを測定した。
フォームの耐久物性(耐候性)として、HACSを測定した。これは、湿熱劣化させた軟質ポリウレタンフォームを一定時間圧縮した際にどれだけ永久圧縮歪みが残るかを測定するものである。よって、この値が小さいほど、耐久物性が良いといえる。
上記コア部分から、縦5cm、横5cm、厚さ2.5cmの寸法でフォームをカットし、これを90℃、相対湿度100%で100時間処理した。その後、70℃、相対湿度5%の条件下、22時間、厚さ方向に50%の圧縮試験を行い、寸法変化率を測定した。HACSを以下の式により計算した。
E:初期の厚さ(cm)
F:圧縮試験後の厚さ(cm)。
