醋酸与醇反应:CH3COOH+C2H5OH=CH3COOC2H5+H2O(条件是加热,浓硫酸催化,可逆反应)ethanoic acid + ethanol= ethyl ethanoate + water (condition is to heat ,with concentrated sulphuric acid as catalyst,a reversible reaction)***醋酸与醇反应这个的条件不是回流加热吗?以防万一,回流加热的翻译是heat under reflux...
Na2SO4·10H2O的相变点仅有32.4qC,前者是克服正、负离子间的静电引力,故熔点,相变点比较高,而后 者除在相变点脱去全部或部分结晶水吸收热量外,还包括更复杂的过程。目前这方面的研究工作没有 突破性进展,但是如不考虑此类物质复杂的相变过程,理论上计算相变潜热值偏差比较大。为此,本文 ...
In order to enhance the water-solubility and biological utilization rate of chrysin,sodium 5,7-dihydroxylflavone-8-sulfonate(1,[Na(H2O)1/2]X,X=C15H9O4SO3,5,7-dihydroxylfla-vone-8-sulfonate) was synthesized and its structure was identified on the basis of NMR,FT-IR and elemental analysi...
Titanocene complexes ([Ti(eta(5)-C5H4R)(2)X-2]; R = H, SiMe3; X = Cl, Er) react with Na(2)H(2)EDTA in aqueous methanol to give an identical product ([Ti(EDTA)(H2O)] by cleavage of the halogen and cyclopentadienyl ligands. The structure of [Ti(EDTA)(H2O)] has been ...
利用三参数的Pitzer模型对25℃下的Na^+‖CrO4^2-,CO3^--H2O三元水盐体系溶解度进行了计算,计算值略低于值;当其中某一组份浓度较低时,计算值与实验值基本一致,当两组份浓度都较高时,计算值与实验值偏差较大.两组...
