Synthesis of tetrahydrofuran
-
, (2008/06/13)
This invention provides a process for producing tetrahydrofuran by the reaction of 3-(5'-alkyl-1',3'-dioxane)-propionaldehyde and/or 3-(5'-alkyl-1',3'-dioxane)propanol and/or 4-hydroxybutanal with hydrogen in an aqueous medium having a pH between about 0.1 and 5. Maintenance of the reaction medium within the specified acidic range of pH is an important feature of the invention process.
Preparation of an acetal from a diol and acrolein
-
, (2008/06/13)
A process for preparing an acetal from acrolein and a 1,3-diol whereby substantially complete conversion of the acrolein to acetal is attained, by simultaneously reacting and separating by extraction the acetal and water formed from said diol and acrolein reaction, said process comprising continuously feeding a 1,3-diol and an acid catalyst countercurrent to a solvent while continuously feeding acrolein to the solvent and diol, separating the acetal-solvent from the diol-water, optionally separating the acetal and solvent and optionally separating the diol and water.
