Upon contacting ethene alone onto MoO3/SiO2 catalyst, propene was detected after induction period. In the induction period, production of 1-butene by dimerization of ethene was recognized and then propene was detected. It was conjectured that the propene formation was caused by metathesis reaction of ethene and 2-butenes following the dimerization of ethene giving 1-butene, and that isomerization of 1-butene giving 2-butenes might be taken place simultaneously via associative mechanism. The results led us to an attempt of ethene homologation on H2(a) adsorbed MoO3/SiO2 and as a result the reaction rate was enhanced on it.
