titleOfInvention | Process for the production of mixtures of 2-hydroxytetrahydrofuran and 4-hydroxybutanal |
abstract | Disclosed is a process for the production of an equilibrium mixture of 2-hydroxytetrahydrofuran and 4-hydroxybutanal by a two-step process comprising (1) heating 2,5-dihydrofuran in the presence of a catalyst system comprising a phosphine, ruthenium or rhodium to convert the 2,5-dihydrofuran to 2,3-dihydrofuran; and (2) contacting 2,3-dihydrofuran with water in the presence of an acidic catalyst to convert the 2,3-dihydrofuran to a mixture of 2-hydroxytetrahydrofuran and 4-hydroxybutanal. Also disclosed is a process for the continuous production of an aqueous solution of 2-hydroxytetrahydrofuran and 4-hydroxybutanal. The mixture of 2-hydroxytetrahydrofuran and 4-hydroxybutanal may be catalytically hydrogenated to produce 1,4-butanediol. |
