Synthesis of new poly-benzoylthiourea and thermal and surface properties

Yeni Bir Polibenzoiltiyoüre’nin Mekanik, Termal ve Yüzey Özellikleri

“…BTP1 (benzoylthiourea polymer 1) and BTP2 (benzoylthiourea polymer 2) polymers were synthesized and characterized according to the literature [8] to compare their mechanical properties with PBTU polymer.…”

“…After 2h stirring at room temperature, the obtained mixture was filtered and obtained precipitate (potassium chloride) was removed. 40 mL of terephthaloyl diisothiocyanate solution was obtained [8]. To a solution of 3,5-diamino-1,2,4-triazole (2.486 g, 0.024 mol) in 40 mL of dichloromethane, terephthaloyl diisothiocyanate filtrates in 1:1 stoichiometry (40 mL) was dropwise added.…”

“…Here, we report a new kind of polybenzoylthiourea polymer (PBTU) synthesized through polyconden sation reaction between 3,5-diamino-1,2,4-triazole and tereftaloyl diisothiocyanate in poly(ethylene glycol)dimethylether as the phase transfer catalyst. While different polybenzoylthiourea derivatives [8] are insoluble in any organic solvents, obtained PBTU is highly soluble in solvents including DMSO and DMF, and show a glass transition temperature. With the synthesis of PBTU, a new polybenzoylthiourea containing triazole and thiourea units in the backbone was synthesized.…”

“…With the synthesis of PBTU, a new polybenzoylthiourea containing triazole and thiourea units in the backbone was synthesized. When PBTU was compared with BTP1 and BTP2 polymers reported in the literature, the main difference was the existence of the triazole unit in the PBTU chain [8].The triazole ring is a heterocyclic aromatic compound with large dipole moment, hydrogen bonding ability and biological activity [9][10][11]. Due to its aromatic structure, the triazole ring shows high stability.…”

Investigation of the Effect of Benzoylthiourea Derivative Fuel Additive N-(5-bromo-pyridin-2-yl)carbonothioyl)furan-2-carboxamide on Engine Performance and Exhaust Emissions in a Spark Ignition Engine

“…Benzoiltiyoüre türevleri, koordinasyon özellikleri nedeniyle, geçiş metal iyonlarına çok sayıda bağlanma olanağı da sağlarlar. Sonuç olarak, platin, rodyum, paladyum, bakır, nikel, kobalt, kadmiyum ve çinko dahil olmak üzere benzoiltiyoüre türevlerinin farklı koordinasyon modlarına sahip çeşitli geçiş metal kompleksleri birçok çalışmada rapor edilmiştir (Kurt, 2008;Schmitt ve ark., 2012;Yang ve ark., 2012;Saeed ve ark., 2014;Mukiza ve ark., 2021;Abdelhamid ve ark., 2021;Zahra ve ark., 2022;Kurt, 2019). Benzoiltiyoüre ile ilgili yapılan başka bir çalışmada N-(5-bromo-pyridin-2-yl)carbonothioyl)furan-2carboxamide ve bunun Cu, Ni ve Co metal kompleksleri hazırlanmış ve yapısal karakterizasyonları elementel analiz, FT-IR, UV-vis., 1 H NMR, tek kristal XRD, manyetik susseptibilite ve DTA/TG teknikleri kullanılarak gerçekleştirilmiştir (Yeşilkaynak ve ark., 2022).…”
