Description
(実施例1)
パーム油169.6g(0.2モル)とグリセリン18.4g(0.2モル)を撹拌装置、温度センサー、および圧力計を備えた5L容積のオートクレーブに入れ、触媒として水酸化カリウム9gを添加し、系内を窒素ガスで置換した後、110℃に昇温し、窒素を吹き込みながら0.04MPa以下の減圧下で脱水を2時間行った。その後、120℃にて0.6MPa以下でプロピレンオキシド278.4g(4.8モル)を徐々に圧入した後、そのまま1時間反応を継続した。次に、エチレンオキシド545.6g(12.4モル)を徐々に圧入し、そのまま1時間反応を継続した。さらに、プロピレンオキシド1972g(34モル)を圧入し、そのまま2時間反応を継続した。反応終了後、窒素を通じながら未反応のアルキレンオキシドを除去し、塩酸を用いて触媒である水酸化カリウムを失活させ、脱水後にろ過を行うことにより本発明の消泡剤2745.3g(収率92%)を得た。
以下、実施例1と同様の方法により表1に示す原料を用いて本発明の消泡剤2〜4、および比較例の消泡剤を得た。
表1中、(EO)/(PO)はランダム付加、(EO)−(PO)はブロック付加を表す。
100mlメスシリンダーにイオン交換水99ml採取し、消泡剤1gを添加した後、スターラーチップ(Ф5mm×20mm)を入れ、1000rpmの速度で撹拌を開始した。撹拌開始から均一に溶解もしくは懸濁するまでの時間について計測し、分散性の指標として表2で評価した。分散性試験の全工程は室温にて行った。
100ml蓋つきサンプル瓶にイオン交換水95g、および消泡剤サンプルを5g仕込み、均一な希釈液になるまで撹拌した後、オートクレーブ高温加圧滅菌装置にて加熱滅菌(120℃、2kPa、20分)を行った直後の外観を観察した。また、その後25℃まで冷却し、その外観についても観察した。これらの結果を表2に示した。
△:1〜3分経過後、水溶液もしくは懸濁液となる
×:均一に分散しない
(注2) ○:均一な水溶液もしくは懸濁液
△:不均一な懸濁液
×:懸濁液内に沈殿または油滴が生成した水溶液もしくは懸濁液
1000mlメスシリンダーに、培地200mlを仕込み、これに[高温安定性試験]に示す方法で消泡剤を希釈して、加熱滅菌したものを、スターラーチップ(Ф5mm×20mm)で1000rpmの速度で撹拌後にサンプリングしてイオン交換水で50倍希釈し、評価系の消泡剤濃度が0.0005〜0.001%となるように、培地に1または2ml添加した。38℃で温度一定に保ったメスシリンダーに、デフューザーストーンから1000ml/分の空気流量にて空気を吹き込み、10分後の泡の高さ(ml)を測定した。この結果を表3に示した。
