A very interesting result was obtained carrying out the reaction in two steps. The total amount of soaps obtained in this case was exactly the same as that obtained when carrying out the reaction in a one-step strategy. Nevertheless, according to the results obtained in this study, it can be concluded that it is possible to optimize the total catalyst dosification in the case of the two-step reaction strategy, decreasing the total catalyst consumption specifically in the second reaction step. This study is currently being carried out.
