. This paper describes the analysis, with respect to individual componen ts, of th ree mlxtmes of olefin hydrocarbons. These were produced by the combination to form dimers of mixed butenes in a t ubul ar type reactor with phosphoric acid as catalyst. P roducts of such reactions ar e called "codimers" and the process " cod imeri zation". The allalyscs w~re made by utilizing di stillations performed at high effici ency with high rcfjux rat io, WIth accurately measured valu es of the boiling point and refractive index of the fraction s of di stillate, and with separation by adsorption of the paraffin por tion of selected distill ate . In the case of on e codimer, u se was made of the previous analysis of t he correspondi ng mixture of paraffins produced by hydrogenation of t he codimer.
