基磺酸物理性质
Physical properties of sulfonic acid
氨基磺酸是一种白色斜方晶体,无味无臭,不挥发、不吸潮,绿色环保,常压时很稳定,其性质可保持数年不变;
Aminosulfonic acid is a white orthorhombic crystal, tasteless, odorless, non-volatile, non-moisture absorption, green, stable at atmospheric pressure, and its properties can remain unchanged for several years.
氨基磺酸易溶于水、液氨和甲酰胺,在水溶液中呈强酸性,微涪于甲醇、丙酮、吡啶、甲酰胺和二甲基甲酰胺等有机溶剂,不溶于乙醇和乙醚。
Aminosulfonic acid is easy to dissolve in water, liquid ammonia and formamide. It is strongly acidic in aqueous solution. It is slightly soluble in organic solvents such as methanol, acetone, pyridine, formamide and dimethyl formamide. It is insoluble in ethanol and ether.
氨基磺酸化学性质
Chemical Properties of Aminosulfonic Acid
氨基磺酸是强酸,电离度很大,别名叫固体硫酸,但其腐蚀性与其它酸如硫酸、盐酸和硝酸相比较低,加入缓蚀剂后,还能够进一步降低腐蚀速率;
Aminosulfonic acid is a strong acid with high ionization, nicknamed solid sulfuric acid, but its corrosivity is lower than other acids such as sulfuric acid, hydrochloric acid and nitric acid. After adding corrosion inhibitor, it can further reduce the corrosion rate.
氨基磺酸能与多种无机化合物、有机化合物进行各种化学反应,其金属盐都是易溶的,因此,氮基磺酸及其盐类具有阻止硫酸钡沉淀的作用。
Aminosulfonic acid can react with a variety of inorganic and organic compounds, and its metal salts are soluble. Therefore, azosulfonic acid and its salts can prevent the precipitation of barium sulfate.
氨基磺酸是具有氨基和磺酸基的双官能团物质,能进行与之有关的许多化学反应.
Aminosulfonic acid is a bifunctional substance with amino and sulfonic groups, which can carry out many chemical reactions related to it.
