Condensation reactions and formation of amides, esters, and nitriles under hydrothermal conditions.
Hydrothermal pyrolysis experiments were performed to assess condensation (dehydration) reactions to amide, ester, and nitrile functionalities from lipid precursors. Beside product formation, organic compound alteration and stability were also evaluated. Mixtures of nonadecanoic acid, hexadecanedioic acid, or hexadecanamide with water, ammonium bicarbonate, and oxalic acid were heated at 300 deg...
متن کاملHydrothermal synthesis, characterization and catalytic performance of La3+ and Sm3+ - doped Bi2Mn2O7 nanocatalysts for Biginelli reactions
La3+ and Sm3+ - doped Bi2Mn2O7 nanocatalysts were synthesized in 1 M NaOH aqueous solution, via a stoichiometric 1:1 Bi:Mn molar ratio hydrothermal method at 180 °C for 48 h. Bi(NO3)3, MnO2, La(NO3)3 and Sm2O3 were used as raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique. Both of the La3+ and Sm3+ - doped Bi2Mn2O7 nanomaterials were cr...
متن کاملStudy on Interfacial Strength Properties between PBO Fiber Modified
1 緒 言 PBO(ポリパラフェニレンベンゾビスオキサゾ-ル) 繊維は,繊維強化複合材料の有機系強化繊維の一つであ り,炭素繊維に匹敵する強度・弾性率を有し,有機繊維 中最高の耐熱性・難燃性を示す事から,FRPの次世代の 強化繊維としての用途展開が期待されている.1), 2) しかしながら,PBO繊維は,繊維/樹脂間の界面強度 が不十分であり,この界面強度は FRPの様々な力学的特 性に大きく影響するため,3)PBO繊維の FRPの強化繊維と しての優れた特性を最大限に活かすためには,界面強度 向上を目的とした繊維表面改質法の研究が不可欠となっ てくる. 現在,繊維/樹脂間の界面強度の向上を目的として, 様々な表面改質法が試みられている.中でも低温プラズ マ処理は,ドライプロセスで低公害であり,繊維自身の 物性を損なうことなく,親水性の官能基を表面に効率的 に付与できるといった利点を...
متن کاملSpeciation of Molybdates under Hydrothermal Conditions
In situ Raman spectroscopy was applied to investigate the speciation of molybdates under hydrothermal conditions in 0.2 M aqueous solution in the temperature range between 20°C and 200°C and at pH values between 7 and 1. The nature and abundance of molecular and supra-molecular species differs significantly compared to the distribution of species under ambient conditions at the same pH. Whereas...
متن کاملThe Relationship between Structural and Optical Properties of GeO2-PbO Glasses
The structural and optical characterization of bulk GeO2-PbO glasses was the goal of this study. In this regard, six different (100-x)GeO2-xPbO (15<x<45) glasses were prepared by conventional melt quenching technique between two steel sheets. The produced samples were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and UV-Vis s...
