Abstract

PURPOSE: To prepare the title compound, by hydroformylating 2-methyl-1-buten-4- ol with H2/CO mixed gas in the presence of rhodium catalyst and an organic phosphorus compound, and distilling the reaction product at a specific temperature.
CONSTITUTION: The title compound is prepared by hydroformylating 2-methyl-1- buten-4-ol in the presence of (A) a rhodium catalyst (e.g. rhodium oxide) and (B) at least 1mol, based on 1g-atom of the rhodium, of a compound I, II, or III (R1,2,5 are hydrocarbons; R3 is H or lower alkyl; R4 is H or hydrocarbon), and distilling the reaction mixture at 75W160°C to separate the unreacted raw material from the reaction product.
EFFECT: The objective compound can be prepared in high selectivity. The catalyst keeps its activity after the distillation, and can be recycled to the reaction system. The reaction proceeds under relatively low pressure.
USE: Precursor 3-methyl-1,5-pentanediol which is raw material of polyester, etc.
