Versuchsvorschrift
In carrying out the reaction to prepare the preferred hexahydro-triazine, the tert-butylamine is added slowly to a concentrated aqueous solution of the formaldehyde (formalin) and the stoichiometry is maintained to so that there is an exact equivalent to a slight excess of the amine at the end of the reaction. Typically, a molar ratio of at least 1.00 to 1.05 of the amine to the formaldehyde is preferred for the overall process to form the tert-butyltriazine quantitatively (in excess of 90% yield). For the reaction to go to completion satisfactorily and to yield the tert-butyltriazine, careful control of the reaction conditions must be observed in order to avoid side-reactions. During the slow addition of the amine it is desirable to maintain a reaction temperature below 46° C.
