By technical reform of the process of propylene oligomerization,the quality and yield of nonene are raised,thus the output of nonylphenol grade one is increased,good economic benefit of the unit is obtained.

The effect of various independent variables which affected the selectivity of nonene during the alkylation of benzene and propylene on phosphate catalyst was studied.

A new technology of producing nonene and dodecene by a two-stage reaction temperaturemethod of propene oligomerization over NiSO_4/γ-Al_2O_3 has been developed.

Benzene perfluorous nonene ether (Ⅱ) was prepared by the reaction of perfluo-rous nonene (C9F18) and phenol,and the molecular structure of which was identified by IR and NMR spectra.

Nitration of toluene with fluorous biphase system was studied by using the perfluorous nonene as solvent.

Compared with the reaction without perfluorous solvent,perfluorous nonene reduces the temperature of esterifications by 10~37 ℃,and raises the yield by 10%~47%.

This paper introduces the sythesis of nonenecarboxylic acid from n heptanal,obtains the kind of catalyst as well as it's quantity and the reacting time demanded in practice and solves the problem of the product treatment afterward.
