Competitive double bond isomerization and competitive esterification of C8 to C18 linear 1-alkenes on amberlyst (R) 15 catalyst: Calculation of relative adsorption coefficients in two concurrent reactions

Relative initial reaction rates for both double bond isomerization and direct esterification with heptanoic acid were determined for the series of linear 1-alkenes from 1-octene to 1-octadecene. In competitive reactions between two 1-alkenes on Amberlyst (R) 15 catalyst at 90 degrees C, rates for both double bond isomerization and esterification decreased with increasing carbon chain length. Data suggested each 1-alkene had two different adsorption coefficients on the catalyst, one for an isomerization site and one for a site for the addition reaction. Results were consistent with previous data suggesting that Amberlyst (R) 15 catalyst has two different types of active sites.

Automated summary

Relative initial reaction rates for both double bond isomerization and direct esterification with heptanoic acid were determined for a series of linear 1-alkenes. The rates for both reactions decreased as the carbon chain length increased. Each 1-alkene showed two different adsorption coefficients on the catalyst, indicating the presence of two types of active sites on the Amberlyst (R) 15 catalyst.
