In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Thermogravimetric and kinetic study of new bis(iminophosphorane)ethane solvates, published in 2020-08-31, which mentions a compound: 1663-45-2, mainly applied to bisiminophosphorane solvate preparation thermal stability crystal structure, Product Details of 1663-45-2.
Thermal and crystallog. characterization of one solvent-free bis(iminophosphorane)ethane (BIPE) form and three solvates with acetonitrile (ACN), DMSO (DMSO) and toluene is presented. Thermal behaviors of new compounds indicate that the solvent is removed differently from the BIPE structure, accordingly with the stoichiometric solvent mol. amount incorporated. Thus, the solvent-free BIPE reveals high thermal stability up to 315°C, while BIPE solvates have a similar pattern behavior with low stability about 130°C. The kinetic parameters of the thermal decomposition process were determined by three different methods Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose and nonparametric kinetic. Crystallog. data revealed that the solvent plays the role of space filler without strong interactions with host mols. Guest-free BIPE, BIPE0.5ACN and BIPE0.35DMSO crystallized in monoclinic C2/c (15) space group, while BIPETOLUENE in a triclinic P – 1 (2) one. Crystallog. and thermogravimetric data show a good correlation between mol. structures and activation energies.
Compound(1663-45-2)Product Details of 1663-45-2 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(1,2-Bis(diphenylphosphino)ethane), if you are interested, you can check out my other related articles.
