国外工业氢甲酰化的现状和发展

Current situation and development of industrial hydroformylation abroad

自 60年前羰基合成 (OXO)技术发现以来 ,形成了非常大的对醛的需求 ,如今已生产出C2～ 1 8链长的醛。其中丙烯转化成丁醇起着最重要的作用。由于产能过剩和替代产品的加入 ,所以这一市场的竞争非常激烈。最具活性的催化剂体系是以含膦配体改性的Rh络合物。人们已经进行各种研究以利用这些体系 ,已经建立起生产NBA、转化长链烯烃的工业工艺体系。随着越来越少的公司生产大部分产品 ,工业研究正在日益集中。工业研究的焦点是催化剂的开发和研制 。

Since the discovery of hydroformylation more than 60 years ago,a very large demand for aldehydes has developed.Today aldehydes having chain lengths of 2-18 carbon atoms are produced by this method.The reaction of propene to butanal plays the most important role here.Competition is very harsh in the markets because of overcapacities and alternative products.The most active catalyst systems are Rh complexes modified with phosphorus contained ligands.Research is being made to carry out these systems,which have been established for the production of butanal,for industrial processes for the reaction of longer chain olefins.Industrial research is being increasingly concentrated,with fewer and fewer companies producing most of these products.The hotspot of industrial research is the development and preparation of catalysts.There is increasing interest in the development of two phase reactions.
