It was established that microwave irradiation solvent-free processing of 2,6-diaminopyridine or 1,3-phenylenediamine with phthalonitrile or 4-tert-butylphthalonitrile led to corresponding hemiporphyrazines I (X = N, CH; Y = H, t-Bu; X = CH, Y = t-Bu, Z = H; X = CH, Y = H, Z = t-Bu) with sufficiently high yields and a huge reduction in the time required for synthesis, from 8-12 h to 20 min. The Knudsen effusion method with mass spectrometric control of vapor composition was applied. The mass spectrometric investigations established that the macrocyclic compounds I give a stable stream of particles and their enthalpies of sublimation were estimated by the second law of thermodn. The results came from multiple reactions, including the reaction of 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 141-86-6)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Recommanded Product: 141-86-6
