A magnesium citrate glycinate co-salt has a formula of Mg2C8H9NO9 - X H2O and a suggested structure of Formula I. The magnesium citrate glycinate co-salt has an apparent density of 1740 kg/m3 and is compressible in a range of compression pressures from approximately 50 MPa to approximately 150 MPa. The magnesium citrate glycinate co-salt is formed by combining citric acid and glycine in a 1:1 molar ratio to form an aqueous reaction mixture and neutralizing the aqueous reaction mixture with a magnesium source having a magnesium:ligand ratio of 1:1.
一种柠檬酸镁甘氨酸共盐的化学式为Mg2C8H9NO9 - X H2O,建议的结构如公式I所示。柠檬酸镁甘氨酸共盐的表观密度为1740千克/立方米,在约50兆帕至约150兆帕的压缩压力范围内可压缩。柠檬酸镁甘氨酸共盐是通过将柠檬酸和甘氨酸按1:1的摩尔比混合形成水溶反应混合物,并用镁源中和具有1:1镁:配体比的水溶反应混合物而形成的。
Phase transition of hollow-porous α-Fe<sub>2</sub>O<sub>3</sub> microsphere based anodes for lithium ion batteries during high rate cycling
subsequent thermal treatment. The superior performance of the as-obtained α-Fe2O3 microspheres as an anodematerial for lithiumionbatteries is evaluated. After 1000 cycles, the capacity still remains more than 1100 mA h g−1 at a current rate of 1 A g−1. Meanwhile, the crystal size induced phasetransition of Fe2O3 microspheres (α → γ → β) is observed during cycling by the measurements of ex situ XRD and

A method of preparing a zinc citrate-containing oral care composition, the method comprising: (a) adding zinc oxide to a solution of citric acid in a solvent to form a suspension; (b) agitating the suspension until a clear solution is obtained; and (c) adding an additional oral care ingredient to the solution obtained in (b). Also, a method of preparing a zinc citrate-containing oral care composition, the method comprising: (a) adding citric acid to a suspension of zinc oxide in a solvent; (b) agitating the suspension until a clear solution is obtained; and (c) adding an additional oral care ingredient to the solution obtained in (b). In both methods, steps (a) and (b) are carried out at a temperature of from 10°C to 50°C and the molar ratio of zinc oxide to citric acid in step (a) is about 3:2.

decomposition behaviour of the citrates of zinc, bismuth and calcium has been investigated individually and as binary mixtures (1:1) consisting of zinccitrate as the essential component. Zinccitrate is found to decompose to zinc oxide at 400 ° C, bismuthcitrate decomposes to α-Bi 2 O 3 at 360 ° C and calciumcitrate decomposes to calcium oxide at 1150°C. The barium and calcium oxides which are normally
摘要 锌、铋和钙的柠檬酸盐的热分解行为已被单独研究,并作为以柠檬酸锌为主要成分的二元混合物 (1:1) 进行了研究。发现柠檬酸锌在400°C分解为氧化锌,柠檬酸铋在360°C分解为α-Bi 2 O 3 ,柠檬酸钙在1150°C分解为氧化钙。通常在柠檬酸单独分解过程中在较高温度下形成的氧化钡和氧化钙在较低温度下获得,即分别在 1140 和 800°C 下与柠檬酸锌的混合物分解。发现单独的柠檬酸铋分解为α-Bi 2 O 3 而其与柠檬酸锌的混合物分解为氧化铋的β相。
