Process for the preparation of 2-alkyl-1,4-butanedial |
| 摘要 |
A process is disclosed for the preparation of 2-alkyl-1,4-butanedial by hydroformylation of acetals of a 2-alkyl-substituted-1-propenal in the presence of a complex rhodium catalyst. The 3-alkyl-4,4-dialkoxybutanal obtained in this manner is separated and hydrolyzed to the desired compound.
