Clear colorless liquid
Uses
3-Methyl-1,3-butanediol is a useful compound in carbon oxygen coupling reactions.
Definition
3-methyl-1,3-butanediol (BDO) is a alkanediols. BDO is preferentially dehydrated into two unsaturated alcohol isomers such as 3M2B1ol and 2-methyl-3-buten-2-ol (2M3B2ol) over CeO2 catalyst at 375 °C. It was found that the selectivity to 3-methyl-3-buten-1-ol was increased by the coke deposition over Al2O3 catalysts in the dehydration of 3-methyl-1,3-butanediol at 200 °C[1].
