The isothermal dissolution equilibrium method and the Schreinemakers method were used to study the two ternary systems(KCl+KB5O8+H2O)and(K2SO4+KB5O8+H2O)at 298.15 K and 101.325 kPa,and the solubilitie
Densities of sodium arsenate(Na3AsO4)aqueous solution with the molality varied from(0.04165 to 0.37306)mol·kg-1 at temperature intervals of 5 K from(283.15 to 363.15)K and 101.325 kPa were measured by
塑性晶体,是一类在固态晶格中质心保持固定位置,而分子或离子呈现转动无序的晶体。有机离子塑晶加入Li+,H+,Na+后,有高离子传导率,全固态电池中可取代现有液体电解质,因极低挥发性、难燃性、结构可调节,是很有潜力、新型固态电解质[1]。在介电材料、铁电材料领域,塑晶也有重要应用前景。
无机盐液体矿产资源主要有盐湖卤水、深层地下卤水、油田卤水和海水,这些液体矿产资源构成了巨大的盐类资源宝库。其中,位于柴达木盆地西部的南翼山地区,在油气勘探时常伴有矿化度很高的卤水喷出(油田水),这些油(气)田水中含有丰富的锂、硼、钾、锶等资源。
以内蒙煤系高岭岩为原料,采用热分析-红外-质谱联用的测试方法对其在煅烧过程中质量、热量、逸出气体产物种类和释放流量等特征进行定性或定量表征。以H2O(g)和CO2(g)的释放特征分别代表脱羟反应和脱碳反应,获得脱羟和脱碳反应的转化率随时间的变化数据,采用非等温动力学方法计算脱碳动力学参数,得到动力学方程。采用动力学方程对煤系高岭岩在不同温度条件下的脱碳过程进行模拟,根据模拟数据拟合出煤系高岭岩完全
As a thermoplastic polymer resin with excellent mechanical property and chemical stability,poly ethylene terephthalate(PET)is widely used in high-strength fibers,packaging,film and plastic bottles.[1-
Polyethylene terephthalate(PET)has been widely used in these years due to its transparent,nontoxic and chemically stable.With the further development of PET applications,the annual consumption and was
碳酸二正丙酯(DPC)是一种重要的绿色化工原料,在有机合成中有着广泛应用。此外,它还被广泛用作石油添加剂、绿色溶剂和电池电解液[1]。另一方面,碳酸二甲酯(DMC)可替代剧毒光气和硫酸二甲酯作为绿色羰基化试剂使用。因而,以正丙醇和DMC 为原料经酯交换法合成DPC 是一条环境友好型路线,符合绿色化学的发展[2]。
