Description
a)不飽和脂肪酸のトリグリセリドと酸化剤とを、不飽和脂肪酸のオレフィンの二重結合の酸化反応のための触媒の存在下に反応させ、中間生成物として、隣接するジオールを得て;
b)工程(a)で得られる前記中間生成物と酸素又は酸素を含む化合物とを、前記隣接するジオールの2つのヒドロキシ基の、カルボン酸基への酸化反応のための触媒の存在下に反応させ、飽和モノカルボン酸(i)と1より多くの酸官能基を有する飽和カルボン酸のトリグリセリド(ii)とを含む反応生成物を得て;該工程(b)は1:1より低い水/ジオール比を有し;
c)1より多くの酸官能基を有する飽和カルボン酸の前記トリグリセリド(ii)から前記飽和モノカルボン酸(i)を分離する
を含むことを特徴とする、不飽和脂肪酸のトリグリセリドを含む未修飾の植物油から出発して、飽和モノカルボン酸及び1より多くの酸官能基を有する飽和カルボン酸のトリグリセリドを製造するための方法に関する。
本発明のもう1つの観点では、前記工程(b)の間、反応生成物は、好ましくは、水相及び有機相の形態で存在する。
本発明のよりさらなる観点では、工程(a)と(b)の両方が、有機溶媒を加えることなく行われる。
有利には、前記分離は工程(b)の終了時に行われる。
水相は、必要であれば工程(a)の触媒との混合物で、工程(b)の触媒を含み、該触媒は、次いで回収され、工程(b)の触媒として任意に再利用されてもよい。
・工程(a)(H2O2との反応)
次の物質:
−高オレイン酸含量のヒマワリ油1000g(オレイン酸82%、リノール酸10%、パルミチン酸4.5%、ステアリン酸3.5%)
−タングステン酸5g(不飽和脂肪酸に対して0.7モル%)
−原料のヒドロキシル化した油50g(前の反応の工程(a)の終了時に得られた中間体、いわゆる「反応活性化剤」)
を反応器中に入れた。温度を60℃〜65℃に上げ、49.9%のH2O2溶液280ccを3時間で加えた。反応の間、プロセスの水の一部を蒸留し、H2O2の過度な希釈を防ぐために窒素をフラックスさせた。H2O2の添加終了後、反応を65℃で、3時間継続した。
工程(a)の終了時に得られた混合物を、攪拌装置を備えたオートクレーブに移した。1%酢酸コバルト水溶液300gを加えた(工程(a)で製造されたジオールに対して0.4モル%)。温度を70℃に上げ、反応器を空気で圧力12atmとした。酸素を十分に供給するために、空気を継続的にフラックスさせた。反応の開始は、酸化開裂の発熱による混合液の温度上昇により明確となった。反応を8時間継続した。
ペラルゴン酸及び短鎖遊離モノカルボン酸360gからなる軽い留分を分離するのに、水蒸気蒸留により油相を蒸留した。蒸留残渣(790g)は、アゼライン酸のトリグリセリドから主になっていた。
実施例1の工程(c)の蒸留終了時に蒸留装置内に残留するトリグリセリドを、180℃で、圧力下、3時間、1:1の比で水を加えることにより加水分解反応に付した。この反応は、グリセロールから一価及び二価の飽和脂肪酸を遊離させた。アゼライン酸及びグリセロールを、90℃で、水を用いた連続抽出により、脂肪酸の混合物から分離した。水溶液を冷却することにより、アゼライン酸370gを結晶化させた。残留水を、塩基性イオン交換樹脂を通過させ、次いで蒸発させ、グリセロール100gを回収した。得られたアゼライン酸の量は、ガスクロマトグラフィ分析により確認すると、アゼライン酸の理論収量に対して約70%に等しいオレイン酸の開裂収量に相当した。
