ABSTRACT:
This invention reveals a process for the synthesis of 2-methylbutanal (2-methylbutyraldehyde). 2-methylbutanal is a chemical intermediate that is useful in the synthesis of isoprene (2-methyl-1,3-butadiene). In utilizing the process of this invention 2-butene is hydroformylated into 2-methylbutanal with only a minimal amount of n-pentanal being produced as a by-product. More specifically, this invention reveals a process for the synthesis of 2-methylbutanal from 2-butene comprising: hydroformylating 2-butene with a catalyst selected from the group consisting of hydridocarbonyltris (triphenylphosphine) cobalt, hydridocarbonyltris (triphenylphosphine) rhodium, and hydridocarbonyltris (triphenylphosphine) iridium in the presence of hydrogen and carbon monoxide wherein said hydroformylation is carried out in the presence of excess triphenylphosphine.
