PROBLEM TO BE SOLVED: To develop a method for producing ditrimethylolpropane (di-TMP) without using conventional n-butyraldehyde, since the method for producing the di-TMP collects the di-TMP as a byproduct of the production of TMP, the content of the di-TMP is low, and therefore, in order to increase the di-TMP production amount, it is necessary to increase the content of the same. SOLUTION: This method for producing the di-TMP is provided by reacting 2-ethyl-2-propenal with formaldehyde and a base. COPYRIGHT: (C)2009,JPO&INPIT |
