The invention provides a process of preparing glycolaldehyde by reacting formaldehyde with hydrogen and carbon monoxide in the presence of a catalyst composition which is based on, a) a source of rhodium, and b) a ligand of general formula R1P-R2(I), wherein R1 is a bivalent radical that together with the phosphorous atom to which it is attached is an optionally substituted 2-phospha-tricyclo[3.3.1.13,7}]-decyl group, wherein from 1 to 5 of the carbon atoms has been replaced by a heteroatom, and wherein R2 is a monovalent radical which is an optionally substituted hydrocarbyl group having from 1 to 40 carbon atoms; a catalyst composition of use in said process; and a process of preparing ethylene glycol from the glycolaldehyde thus prepared.
该发明提供了一种制备甘醛的方法,通过在催化剂组合物的存在下,将甲醛与氢气和一氧化碳反应,所述催化剂组合物基于a)铑的来源,和b)一般式R1P-R2(I)的配体,其中R1是一个二价基团,与其连接的磷原子一起是一个可选择替代的2-磷杂-三环[3.3.1.13,7}]-癸基团,其中1到5个碳原子已被杂原子取代,而R2是一个单价基团,是一个可选择替代的碳氢基团,含有1到40个碳原子;用于该方法的催化剂组合物;以及从制备的甘醛制备乙二醇的方法。
