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 Calorimetric and theoretical investigation of heat effects and reaction kinetics for nitration of 2-methyl-4,6-dihydroxypyrimidine (MDP), published in 2012-09-30, which mentions a compound: 1194-22-5, mainly applied to calorimetric theor heat kinetics nitration methyldihydroxypyrimidine MDP, COA of Formula: C5H6N2O2.
The thermal effects accompanying the process of nitration of 2-methyl-4,6-dihydroxypyrimidine (MDP) were studied. Measurements were performed using a reaction calorimeter DRC Evolution delivered by Setaram. The heat of solution of MDP in concentrated sulfuric acid (95%), the heat of mixing of nitric acid (100%) with sulfuric acid (95%) and the heating effect of nitration of MDP in a mixture of nitric and sulfuric acids were measured. The heat of solution of MDP was 95 ± 3 kj/mol, while the total heat effect of nitration MDP was 392 ± 9 kj/mol. The measured heat of solution of acids was 34 ± 2 kJ/mol HNO3. Anal. of literature data and own research allowed us to propose the model of kinetics for nitration of MDP. The model was used to simulate phenomena and reactions running in the reaction calorimeter. The exptl. data were compared with modeling results. The parameters of the rate constants of reactions running in the calorimeter were determined as a model for preparation of 1,1-diamino-2,2-dinitroethene (DADNE).
There are many compounds similar to this compound(1194-22-5)COA of Formula: C5H6N2O2. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
