Abstract
La presente invención se relaciona con un proceso para lasíntesis de poliéster ácido graso de poliol por transesterificación de poliol, que comprende la reacción del poliol con una primera porción de éster alquilo ácido graso inferior para producir un producto de reacción de primer paso en el cual todo el poliol es reaccionado substancialmente con al menos un éster alquilo ácido graso inferior, dada una columna de etapas múltiples en donde cada etapa está separada por una etapa adyacente anterior con una plaza de segmento y cada plaza de segmento está provista con al menos un conducto que permite la transferencia de un líquido en una primera dirección entre etapas adyacentes y con al menos un conducto que permite la transferencia de un gas en una segunda dirección entre etapas adyacentes, siendo la segunda dirección a contra corriente de la primera dirección, alimentar el producto de reacción de primer paso y una segunda porción de éster alquilo ácido graso inferior a la columna, para causar la reacción del producto de reacción de primer paso y el éster alquilo ácido graso inferior y formar una mezcla líquida que contiene poliol esterificado parcialmente, éster alquilo ácido graso inferior y subproducto alcohol alquilo inferior, pasar la mezcla líquida en la primera dirección entre etapas adyacentes a través de la columna, por medio de lo cual ocurre la reacción adicional del poliol parcialmente esterificado y del éster alquilo ácido graso inferior para formar un producto poliéster de poliol, alimentar un gas inerte a través de la columna en la segunda dirección entre etapas adyacentes, a contra corriente del flujo de la mezcla líquida en la primera dirección, con agitación que produzca corte radialmente para incrementar el contacto gas-líquido entre el gas inerte y la mezcla líquida, por medio de lo cual el subproducto alcohol alquilo inferior de la reacción de transesterificación es transferido desde la mezcla líquida al gas inerte.
