description PROCESO PARA PREPARAR 2 - ALQUIL - 1,4 - BUTANODIOLES Y MEZCLAS CON 1,4 - BUTANODIOL QUE COMPRENDE PONER EN CONTACTO, A UN PH ALCALINO INICIAL, Y A UNAS TEMPERATURA Y PRESION ADECUADAS PARA LA REACCION, UNA MEZCLA DE 4 - HIDROXIBUTIRALDEHIDO Y/O SU ACETAL CICLICO, 2 - HIDROXITETRAHIDROFURANO, HIDROFORMALDEHIDO, Y UN CATALIZADOR DE HIDROGENACION. TAMBIEN SE DESCRIBEN PROCESOS PARA PREPARAR MEZCLAS DE TETRAHIDROFURANO Y 3 - ALQUILTETRAHIDROFURANO A PARTIR DE LAS MEZCLAS DE DIOLES, Y COPOLINEROS A PARTIR DE MEZCLAS DE TETRAHIDROFURANO. Process for preparing 2-alkyl-1,4-butanediols and mixtures with 1,4-butanediol which comprises bringing together, at an initial alkaline pH, and at a temperature and pressure suitable for reaction, a mixture of 4-hydroxybutyraldehyde and/or its cyclic acetal, 2-hydroxytetrahydrofuran, hydrogen, an unsubstituted aliphatic aldehyde, especially formaldehyde, and a hydrogenation catalyst. Also processes for preparing mixtures of tetrahydrofuran and 3-alkyltetrahydrofuran from the diol mixtures, and copolymers from the tetrahydrofuran mixtures.
