O-Xylene → 5-Ortho-tolylpentene

Participants

Reaction Steps

Using the equipment and procedure described in Example I a run was made using an alloy of 0.1% sodium and 0.1% potassium based on the weight of the xylene and another run with the same alloy was made adding 0.09% TMEDA. Both runs were made using butadiene having 155 ppm water which decreased activity but the effect of the amine cocatalyst is indicated by a trans:cis ratio 2.11 compared to 1.35 for the alloy alone, and by cumulative yield of 59.7% 5-OTP compared to 40% for the alloy alone. Other examples are listed in Table I.
