摘要:
A process for production of higher linear alpha olefins and/or alkyl-branched alpha olefins, which comprises the co-oligomerisation of one or more alpha olefins with ethylene in the presence of a metal catalyst system employing one or more bis-aryliminepyridine MXa complexes and/or one or more [bis-aryliminepyridine MYp.Lb+][NC−]q complexes; and said process is carried out at an ethylene pressure of less than 2.5 MPa.

摘要:
A process for preparing styrene by contacting a gaseous feed which contains 1-phenylethanol and at least 0.1% wt of phenol and/or ethylphenol with a heterogeneous dehydration catalyst in the presence of at least 0.40% wt of benzylalcohol and at a molar ratio of benzylalcohol to total amount of phenol and ethylphenol of at least 0.8.
