Abstract

Mejoras en el objeto de la patente principal, nº 244576, por: Procedimiento para la preparación de compuestos alfa-beta-delta-epsilon-insaturados, de la fórmula general: R - CH = CH - CH2 - CH = CH - COOR1 en la cual R es H, un fenilo o un residuo orgánico alifático o cicloalifático que contiene de 1 a 10 átomos de carbono, el cual puede substituirse también por grupos inertes en las condiciones de reacción, con tal de que estos no sean substituyentes electronegativos en posición conjugada con enlace doble, y R1 es H o un residuo alifático o cicloalifático o arilalifático, saturado, lineal o ramificado, que tenga de 1 a 10 átomos de carbono, cuyas mejoras se caracterizan por el hecho de que se hacen reaccionar los compuestos siguientes: alcoholes dotados de la fórmula R - CH = CH - CH2OH (en la que R tiene el significado indicado antes), compuestos ROH hidroxilados, en exceso de 50% por lo menos respecto a la proporción estoiquiométrica (calculada a base del grupo que incluye agua y alcoholes saturados, lineales o ramificados, alifáticos, cicloalifáticos o arilalifáticos, dotados de 1 a 10 átomos de carbono), mezclas de acetileno y óxido carbónico que contengan de 25 a 75% de óxido carbónico, niquel-carbonilo y ácido clorhídrico, hallándose este último en defecto respecto al niquel-carbonilo, a temperaturas situadas enter 35 y 65ºC.
