title: [Transformation of tetrahydro-1,3-oxazine into 1,3,5-tris(3-hydroxypropyl)-hexahydro-1,3,5-triazine--a question of stability (author's transl)].
abstract: At room temperature tetrahydro-1,3-oxazine (THO) is converted into the very viscous 1,3,5-tris(3-hydroxypropyl)-hexahydro-1,3,5-triazine (THT) over several weeks. On heating to ca. 125 degrees C THO will be reformed from THT. The structure of THT was proven by mass-, 1H- and 13C-NMR spectra.
