Abstract

A preliminary attempt to modify a molybdena-silica for ethylene homologation was performed by adding copper. Ethylene homologation (3C2H4→2C3H6) was enhanced 2.5 times on copper doped catalyst. Contrary to this, ethylene metathesis (C2H4−12C2+C2H4−13C2→2C2H4−13C1) was suppressed in the presence of copper. The selectivity of the homologation to metathesis was increased 7.5 times.

Abstract

Проведены предварительные попытки модифицирования окиси молибдена-окиси кремния, используемых в гомологировании этилена (3C2H4→2C3H6), добавлением меди. На катализаторах с добавкой меди зта реакция ускорялась в 2,5 раза, а метатезис этилена (C2H4−12C2+C2H4−13C2→2C2H4−13C1) уменьшался. Селективность гомологирования к метатезису повышалась в 7,5 раз.
