Aluminum-alkyl-based Aujbaureaktion Growth Reaction

Aluminum-alkyl-based Aujbaureaktion (Growth Reaction) 

To calculate the product distribution of ethylene oligomerization, the reaction orders for the insertion and the elimination steps with respect to ethylene are highly relevant. For most ethylene oligomerization processes, it is reasonable to assume that ethylene insertion is first order with respect to ethylene concentration while elimination is zero order with respect to ethylene. Under these preconditions, Eq. (6.16.1) describes the so-called coefHcient that gives the ratio of the rates of elimination over insertion (Onken and Behr 1996)  

2) shows a different picture with maxinia of mass share for certain higher 1-alkene fractions depending on the coefficient. 

From a technical point of view, a Scdiulz-Flory type distribution of 1-olefins is problematic as 1-butene, which is always produced in the highest molar amount, is less desired for industrial applications compared to, for example, l-Q, 1-Cg, or the detergent range 1-alkenes. 

These two components are separated in a second distillation column (DC2) with AIBU3 being transferred over-head back to the stoichiometric reactor to serve as reaction partner for chain growth while the longer chain products are isolated as commercial products.
