PROCESS FOR CONVERTING ETHYLENE TO NORMAL ALPHA OLEFINS

摘要

1315067 Oligomerizing ethylene GULF RESEARCH & DEVELOPMENT CO 18 Aug 1971 [27 Aug 1970] 38749/71 Heading C5E Ethylene is oligomerized to give predominantly normal alpha olefins by heating the ethylene stream containing less than 3 wt. per cent ethane with a trihydrocarbyl aluminium compound at an elevated temperature and at a pressure of at least 35 kg./cm.2. The reaction may be effected at 141-324‹ C. in an elongated coil in the presence of 1 X 10-4 to 1 x 10-2 moles Et 3 Al per mole ethylene. Unconverted ethylene may be recycled to the reaction.
