Abstract

La presente invención se refiere a un proceso para preparar polibuteno de bajo peso molecular que tiene un Mn dentro de la escala de aproximadamente 700 a aproximadamente 3000 y una distribución de peso molecular de menos de aproximadamente 2.0 a partir de una mezcla de corriente de alimentación de hidrocarburo de 4 átomos de carbono que contiene por lo menos aproximadamente 6 por ciento en peso de isobutileno, en una zona de reacción agitada mantenida a temperatura de aproximadamente -50 a +30 grados C, que comprende: a) inyectar el HC1 en una cantidad de aproximadamente 25 a 300 partes en peso por un millón de partes en peso de la mezcla de la corriente de alimentación hacia la mezcla de la corriente de alimentación, b) introducir simultáneamente la mezcla de la corriente de alimetnación tratada y el catalizador de cloruro de organoaluminio como corrientes separadas hacia la zona de reacción; c) poner en contacto la mezcla de la corriente de alimentación tratada introducida y el catalizador introducido en la zona de reacción durante un período de tiempo bajo condiciones suficientes para formar una mezcla de reacción de polimerización que contiene el polibuteno; d) retirar la mezcla de reacción de polimerización desde la zona de reacción; y e) recuperar el producto de polibuteno de la mezcla de reacción de polimerización retirada.
