a novel sol gel synthetic route to alumina nanofibers via aluminum nitrate and Hexamethylenetetramine
Materials Letters, 2007Co-Authors: Jianqiang Wang, Youzhen Wang, Minghua QiaoAbstract:Abstract Attempts have been made to prepare alumina nanofibers by hydrolyzing aluminum nitrate in the presence of Hexamethylenetetramine (HMTA) followed by the supercritical fluid drying (SCFD) process. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and nitrogen physisorption. The results show that δ-Al2O3 nanofibers with diameter of 2 nm, length of 50 nm and with BET surface areas of 412.6 m2 g− 1 were successfully synthesized. The thermal evolution of the fibers and the role of Hexamethylenetetramine were also briefly discussed.

Spectrophotometric determination of Hexamethylenetetramine
The Analyst, 1992Co-Authors: Gary L. Madsen, Bruno JaselskisAbstract:A spectrophotometric method has been developed for the quantitative determination of aqueous Hexamethylenetetramine (HMT) alone, in the presence of large amounts of formaldehyde, and in the presence of urine. The method is based on the perchloric acid hydrolysis of HMT to formaldehyde, oxidation of formaldehyde by hydrous silver(I) oxide, and oxidation of silver(O) with iron(III) in the presence of FerroZine. Optimum conditions were developed and HMT was determined over the range from 3 × 10–7 to 3.3 × 10–6 mol dm–3. The method developed is approximately 7.5 times more sensitive than the chromotropic acid method.
