    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 .beta.-methyl-.delta.-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: A process for producing 7-octen-1-al by isomerization of 2,7.octadien-1-ol by feeding 2,7-octadien-1-ol and hydrogen to a reaction zone in the presence of a copper catalyst while controlling the molar ratio of 2,7-octadien-1-ol to hydrogen within a range of 99/1 to 75/25, and effecting isomerization in the gaseous phase. This process ensures a high yield, a high selectivity and stable operation over a long period of time.
