    摘要： The hydroformylation of 3-methyl-3-buten-1-ol with hydrogen and carbon monoxide, when carried out under relatively mild conditions, gives 2-hydroxy-­4-methyltetrahydropyran (MHP) in high rate of reaction and in high selectivity even in a very low rhodium catalyst concentration. MHP is useful as a starting material for the production of 3-methyl-1,5-pentanediol and β-methyl-δ-valerolactone which are in turn usable as raw materials for producing polyesters and polyurethanes. The process according to the invention can give such MHP advantageously from the industrial viewpoint and has very great industrial utility.

    摘要： Butadiene and water are reacted continuously in the presence of a solvent capable of dissolving both reactants at least partially and a palladium catalyst With the mole ratio of butadiene to the reaction product octa-2,7-dien-1-ol in the reaction mixture being maintained at 0.6 or more. By this process, octa-2,7-­dien-1-ol can be produced continuously without reduc­tions in reaction rate and selectivity and with decreased insoluble polymer formation.
