Esters of cyclohexane polycarboxylic acids are used as plasticisers for polyvinyl chloride to enable products with comparable mechanical properties to be obtained using less polyvinyl chloride. Use of these esters also produces formulations with increased stability to ultra-violet light, improved lo ...

This invention is to a method of oligomerizing an olefin feed stream. The olefin feed stream contains at least one C2 to C12 olefin to obtain an olefin feed stream and has less than 1,000 ppm by weight oxygenated hydrocarbon. The olefin is oligomerized by contacting with an acid based oligomerizatio ...

ExxonMobil Chemical Patents, Andrew B Griffis, September 16, 2008: US07425662 (12 worldwide citation)

A selectivated molecular sieve, e.g., ZSM-22 or ZSM-23, is used as olefin oligomerization catalyst to provide product, e.g., octenes and dodecenes from butene, having a low degree of branching and hindered double bonds.

The gas cycle in a high pressure hydroformylation reaction using a series of at least two reactors is controlled to optimise yield, conversion and selectivity and to control reaction temperature. The control is achieved through balancing fresh gases and recycle gases in each of the reactors and as a ...

Ronald D Garton, James T Ritchie, Raphael Frans Caers: Oxo process. ExxonMobil Chemical Patent, Andrew B Griffis, July 25, 2006: US07081554 (4 worldwide citation)

The Oxo Process that recycles its cobalt primarily as cobalt salt is improved by concentration of the cobalt salt solution from the demetalling section and the addition of a separation step for organic acid and water. This allows for a higher reuse of acid in the process and thus a lower amount of a ...
