PROCEDIMENTO PER LA PRODUZIONE DI POLIISOBUTENI |
摘要 |
A process for selectively producing liquid polyisobutene contacting a feed stream containing mixed butenes with a dry chlorinated alumina catalyst at a temperature of from about -15 DEG to about 50 DEG C. wherein the chlorinated alumina contains from about 2 to 20% by weight of chlorine and the alumina has a purity of at least 99% and a surface area greater than 150 m2/g with at least 10% of the pores having a mean diameter larger than 200A and recovering polyisobutenes having a molecular weight between about 280 and 4000. |
