The present invention relates to a method of producing butene-1. According to the invention, the method of producing butene-1 resides in dimerizing ethylene in the presence of a complex organometallic catalyst of the formula (RO).sub.3 TiR' .AlR.sub.2 'OR + AlR.sub.2 'R', where R is an alkyl radical with from 2 to 4 carbon atoms, R' = R or H, R' is the same as R, or a catalyst having the formula Ti(OR).sub.4 + AlR.sub.2 'R' and modifiers such as (C.sub.5 H.sub.5).sub.2 TiCl.sub.2, oxygen, metaphenylenediamine or N-phenyl-.beta.-naphthylamine, in the medium of solvents such as n-heptane, n-decane, toluene, diethyl ether, ethyl chloride, vinylbutyl ether, tetrahydrofuran, diphenyl ether, methylphenyl ether and mixtures thereof. The invention will find application in petrochemical processing.

An analyser for the determination of double bonds in organic compounds comprises a reactor containing a compound to be tested through which passes an ozone-oxygen or ozone-air mixture. The gas outlet of the reactor is connected to a measuring cell which is mounted between a source and receiver of ultraviolet radiation, with the receiver being connected to the input of an integrating unit which is adapted to measure the area of a figure described by a time-dependent electric signal, which area is directly proportional to the number of double bonds in the compound being tested.
