The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

ABSTRAKT

When hexamethylenetetramine (HMTA) was treated with cupric perchlorate at room temperature, protonation at one of the N atoms, it yielded protonated HMTA perchlorate (PHMTAP), C6H13ClN4O4 . It crystallizes in a monoclinic crystal system with the P21/n space group. On the other hand, when HMTA was treated with 20% perchloric acid in the absence of cupric perchlorate, the resulting product was ammonium perchlorate (AP), which crystallizes in an orthorhombic crystal system with the Pnma space group. Both PHMTAP and AP have been characterized by X-ray crystallography using a Nonius Kappa charge coupled device diffractometer. Thermolysis has been carried out by thermogravimetric, differential thermal analysis, ignition/explosion delay, and burning-rate measurements. The results have shown that PHMTAP salt was thermally less stable than AP.
