Abstract
A method of making di-TMP includes reacting TMP and a dialkyl carbonate in the presence of a base catalyst in a reaction medium to form an oxetane of TMP in the reaction medium; providing additional TMP and an acid catalyst to the reaction mixture and reacting the oxetane in situ with the additional TMP to produce di-TMP; and recovering di-TMP. The process may be carried out in sequential reaction zones by feeding the reaction medium forward or carried out sequentially in a single reactor. Preferably, one or all of the following conditions are met: (i) said acid catalyst is a strong acid catalyst or (ii) said base catalyst is a strong base catalyst; or (iii) the molar ratio of TMP/dialkyl carbonate employed in the method is greater than 2.5.
