日本大坂大学一些研究工作者在探索规整性聚乙醛用的催化剂的科学试验中取得了重要的进展。这种催化剂是一些新型的金属有机化合物,具有如M[R_2AlOAlR′_3]的通式。另一个相似的系统,是以N-苯基基团代替了上速通式中的氧原子。这一个新的合成方法给制备许多含有现代烷基基团的催化剂提供了可能性。他们所用的合成方法是:使R_2AlOLi 的甲苯溶液(作为Lewis 碱)与AlR′_3的甲苯溶液(作为Lewis 酸)
Some researchers at the University of Osaka in Japan made important progress in the scientific experiments to explore catalysts for regular polyaldehyde acetalization. This catalyst is a new class of organometallic compounds with the general formula M [R 2 AlOAlR’_3]. Another similar system replaces the oxygen atom in the supersonic formula with an N-phenyl group. This new synthesis gives the possibility of preparing many catalysts containing modern alkyl groups. The synthesis method they used was to make the toluene solution of R 2 AlOLi (as Lewis base) and the toluene solution of AlR’_3 (as Lewis acid)
