【発明の属する技術分野】
本発明は、アルコキシル化触媒に関する。詳しくは、特定の金属酸化物からなるアルコキシル化触媒、および該触媒を用いて行う、副生成物が少なく、重合度分布が狭い、アルコキシレートの製造方法に関する。
【0002】
【従来の技術】
高級アルコール、アルキルフェノール、脂肪酸、アルキルアミン等の活性水素含有化合物は、アルキレンオキサイドとの付加重合により、疎水基の構造と親水基の構造を自由に組み合わせることができるので、家庭用洗剤および工業用界面活性剤、さらにアニオン界面活性剤の原料として広範な用途に利用されている。これらの活性水素を持つ化合物とアルキレンオキサイドから得られるアルコキシレートを製造するためには、従来より触媒として、苛性ソーダ、苛性カリ、トリエチルアミン等の塩基性触媒や三弗化ホウ素コンプレックス(エーテラート等)や五塩化アンチモン等の酸性触媒が用いられている。
【0003】
【発明が解決しようとする課題】
しかしながら、これらの公知の触媒には以下のような欠点がある。
【0004】
すなわち、塩基性触媒を用いた場合は、副生成物が少なく、重合度が高いものが容易に得られるが、重合度分布が広くなり、高級アルコール等の活性水素含有化合物の未反応物からアルキレンオキサイドの重合度の高いものまで含む混合物となる。未反応物が多いと重合物の臭気が強く、重合物の石油エーテル可溶分等の値が高くなるので、洗浄用の界面活性剤としての使用には問題があり、また、アルキレンオキサイドの重合度が高いものが多いと、疎水性と親水性のバランスが崩れるので、界面活性剤としての性能の低下等が問題となる。
【0005】
一方、酸性触媒を用いた場合は、高級アルコール等の活性水素含有化合物の未反応物は少なくなるが、ポリアルキレングリコールやジオキサン、ジオキソラン等の望ましくない副生成物が多く生成する。また、酸性触媒は、金属に対する腐食性が強いので、使用する装置が限定され、工業用触媒として不具合な点を有する。
【0006】
重合度分布が狭く、副生成物が少なくなる触媒としては、ハロゲン化物(特開昭60−29370号、特開平2−227426号公報)、複合金属酸化物(特開平1−164437号、特開平2−71841号、特開平6−322098号、特開平7−227540号公報)、ポリフィリン(特公平5−14734号公報)等が提案されている。
【0007】
しかし、これらの触媒には次のような問題点がある。
【0008】
例えば、ハロゲン化物の触媒は、金属に対する腐食性があるので、装置が限定され、またポリフィリンは、触媒活性が低いため、反応時間が非常に長くなり、いずれも工業的には有利であるとはいえない。
【0009】
一方、複合酸化物の触媒では、アルコキシレートの重合度の分布は狭いものの、触媒を除去するための濾過行程に時間を要し、工業的には問題があったので、最近では、より高く活性化して触媒添加量を減らすことにより、濾過行程の効率化が図られている。
【0010】
本発明は上記に鑑みてなされたものであり、濾過行程の効率が向上し、なおかつアルコキシレートの重合度の分布が狭く、副生成物が少なくなる高い触媒活性を持ったアルコキシル化触媒、およびその触媒を用いるアルコキシレートの製造方法を提供することを目的とする。

【発明の効果】
請求項1のアルコキシル化触媒は、重合度分布が狭く、しかも未反応原料や副生成物が少ないアルコキシレートが製造でき、中和工程が省略できるので、産業上大きな価値がある。
【0053】
特に、岩塩型構造をとる金属酸化物の金属元素が、カルシウム、ストロンチウム、バリウム、マンガンからなる群から選ばれた一種又は二種以上であることにより、上記に加えて触媒の活性が高いため、製造時間の面でも従来のものと比較して遜色がない。
【0054】
さらに、亜族方式周期律表の第3A族、3B族、5A族、7A族、8族およびランタノイド類から選ばれた元素として、アルミニウム、ガリウム、インジウム、マンガン、プラセオジウムからなる群から選ばれた一種又は二種以上を含有することから、未反応原料や副生成物がほとんどなく、また触媒の活性が高いことにより製造時間が短縮できる上に、反応物から容易に触媒を除去できるため、濾過行程での効率が向上する。
【0055】
また、亜族方式周期律表の第3A族、3B族、5A族、7A族、8族及びランタノイド類から選ばれた元素の含有量が、前記岩塩型構造をとる金属酸化物の金属元素1.0に対し、0.001〜0.5の割合(但し組成比)であることによっても、未反応原料や副生成物がほとんどなく、触媒の活性が高いため、製造時間の面で有利である。
【0056】
請求項2の製造方法によれば、上記したような、重合度分布が狭く、未反応原料や副生成物が少ないアルコキシレートが容易に効率よく製造できる。

BACKGROUND OF THE INVENTION
The present invention relates to an alkoxylation catalyst. Specifically, the present invention relates to an alkoxylation catalyst comprising a specific metal oxide, and a method for producing an alkoxylate, which is carried out by using the catalyst and has few by-products and has a narrow polymerization degree distribution.
[0002]
[Prior art]
Active hydrogen-containing compounds such as higher alcohols, alkylphenols, fatty acids, and alkylamines can be combined freely with the structure of hydrophobic groups and hydrophilic groups by addition polymerization with alkylene oxide. It is used in a wide range of applications as a raw material for activators and anionic surfactants. In order to produce alkoxylates obtained from these active hydrogen-containing compounds and alkylene oxides, conventional catalysts such as caustic soda, caustic potash, triethylamine, boron trifluoride complexes (such as etherate) and pentachloride have been used as catalysts. An acidic catalyst such as antimony is used.
[0003]
[Problems to be solved by the invention]
However, these known catalysts have the following disadvantages.
[0004]
That is, when a basic catalyst is used, a by-product with a low degree of by-products and a high degree of polymerization can be easily obtained. A mixture containing even a high degree of polymerization of oxide. If there are many unreacted substances, the odor of the polymer is strong and the value of the petroleum ether soluble matter of the polymer is high, so there is a problem in use as a surfactant for washing, and the polymerization of alkylene oxide If the degree is high, the balance between hydrophobicity and hydrophilicity is lost, so that the performance as a surfactant deteriorates.
[0005]
On the other hand, when an acidic catalyst is used, an unreacted product of an active hydrogen-containing compound such as a higher alcohol is reduced, but many undesirable by-products such as polyalkylene glycol, dioxane and dioxolane are generated. Moreover, since an acidic catalyst has strong corrosiveness with respect to a metal, the apparatus to be used is limited and has a fault as an industrial catalyst.
[0006]
Examples of the catalyst having a narrow polymerization degree distribution and less by-products include halides (Japanese Patent Laid-Open Nos. 60-29370 and 2-227426) and composite metal oxides (Japanese Patent Laid-Open No. 1-164437 and Japanese Patent Laid-Open No. No. 2-71841, JP-A-6-322098, JP-A-7-227540), and polyphyrin (Japanese Patent Publication No. 5-14734) have been proposed.
[0007]
However, these catalysts have the following problems.
[0008]
For example, halide catalysts are corrosive to metals, so the equipment is limited, and polyphyrins have low catalytic activity, resulting in very long reaction times, both of which are industrially advantageous. I can't say that.
[0009]
On the other hand, in the composite oxide catalyst, although the distribution of the degree of polymerization of the alkoxylate is narrow, it took time for the filtration process to remove the catalyst, and there was an industrial problem. The efficiency of the filtration process is improved by reducing the catalyst addition amount.
[0010]
The present invention has been made in view of the above, and an alkoxylation catalyst having a high catalytic activity in which the efficiency of the filtration process is improved, the distribution of the degree of polymerization of the alkoxylate is narrow, and by-products are reduced, and its It aims at providing the manufacturing method of the alkoxylate using a catalyst.
