A new polymorph of HMTD
Date of Original Version
While exploring the synthesis pathway of HMTD, an unexpected new route for preparing HMTD was found through the reaction of formaldehyde, hydrogen peroxide, and ammonium hydroxide. The recovered HMTD was characterized by Raman spectroscopy and powder x-ray diffraction and found to be a different crystal structure. This HMTD is believed to be the result of a different conformation of the HMTD, only previously predicted by computational methods and through the use of specialized NMR reagents.
