Abstract

Procedimiento para la preparación de oligocarbonatodioles alifáticos con un grado de protección de los grupos OH terminales con grupos metoxicarbonilo inferior al 5%, por reacción de carbonato de dimetilo con dioles alifáticos con un grado de transformación del carbonato de dimetilo utilizado superior al 80%, caracterizado porque la reacción del carbonato de dimetilo y los dioles alifáticos acelerada mediante catalizadores solubles se realiza en un dispositivo de paso en contracorriente gas-líquido, seguida de una oligomerización con disociación de metanol y trazas de carbonato de dimetilo en un dispositivo que genera burbujas de gas en el oligocarbonato.
