A dimerization reaction of ethylene is used to form 1-butene by the following reaction:
H2​C=CH2​+H2​C=CH2​⟶H3​CCH2​HC□CH2​
The process is a liquid phase reaction that takes place 25∘C. The initial feed to the reactor is pure ethylene and 20% (mole-wise) of ethylene is converted to 1 -butene at equilibrium. Assuming the non-ideal solution behavior of the system can be described by:
Gᴱ/RT​=AxB​xE​ Where:
A is a scaling coefficient
XB​ is the mole fraction of 1-butene
XE​ is the mole fraction of ethylene
