Description
温度計、窒素導入管、攪拌機及びジムロート冷却管と容量30mLの油水分離管とを取り付けた2Lの4つ口フラスコ(反応器)に、表1,2に示す割合で混合した2−エチルヘキサン酸と3,5,5−トリメチルヘキサン酸との混合脂肪酸、及びペンタエリスリトールを、混合脂肪酸:ペンタエリスリトール=5:1の割合(モル比)で仕込んだ。必要に応じて触媒を更に仕込んだ後、窒素気流下、反応器をマントルヒーターで加熱し、反応器が200℃に達した後、エステルの水酸基が3mgKOH/g以下となるまで、混合脂肪酸とペンタエリスリトールとを反応させた。その後、反応器内を50Torrまで減圧し、酸価が5mgKOH/g以下となるまで過剰の脂肪酸を留去した。85℃まで反応器を冷却した後、上記の酸価から算出される水酸化カリウム量の1.5当量をイオン交換水で希釈して10%の水溶液を作製し、それを反応液に加えて1時間撹拌した。撹拌を止めた後、30分静置して下層に分離した水層を除去した。次に、反応液全量に対して20質量%のイオン交換水を加えて85℃で10分撹拌して、15分静置した後、分離した水層を除去する操作を5回繰り返した。その後、100℃、30Torrで1時間撹拌することで脱水した。最後に、反応液全量に対して2質量%の活性白土を加え、80℃、30Torrの条件で1時間撹拌し、ろ過して吸着剤を除去することで所望のエステルを得た。

エステルb:2−エチルヘキサン酸とペンタエリスリトールとのテトラエステル
エステルc:3,5,5−トリメチルヘキサン酸とペンタエリスリトールとのテトラエステル
得られた基油について、以下に示す試験方法に従って、Mw/Mn、引火点及び自然発火点の測定、並びに低温析出性試験を行った。結果を表1,2に示す。
溶剤としてクロロホルムを使用し、各基油を希釈して試料濃度を1質量%とした溶液を調製した。その溶液を、GPC装置(Waters Alliance2695)を用いて分析を行った。溶剤の流速は1ml/min、分析可能分子量100から10,000のカラムを使用し、屈折率検出器を用いて分析を実施した。なお、分子量が明確なポリプロピレングリコール標準を用いてカラム保持時間と分子量との関係を求め、検量線を別途作成した上で、得られた保持時間から分子量を決定した。
引火点:JIS K2265−4:2007
自然発火点:ASTM E 659−1978
各基油を試験管に入れ、ドライアイスを入れたエタノール浴(−70℃)に24時間浸漬した後の基油における白濁の有無を観察した。
