Optimisation of Heterogeneous Catalysed Esterification Reaction for n-Hexyl Acetate Synthesis part 2 Introduction continued Blagov et al. (2006) explored the catalysed esterification with n-butanol observing the effect on conversion and selectivity of ester from various catalyst brands. Most notably, at higher catalyst loadings, particularly at 10-15%, they detected the formation of side-products (olefins and ethers). […]
