1.在常温枯燥的环境中,氨基磺酸比较安稳,只需坚持不与水触摸,固体的不吸湿。在高温时分化,放出氮、硫的氧化物等毒性气体。氨基磺酸及其盐类与多种金属化合物都能生成可溶性盐类。260℃时分化。溶于水、液氨,微溶于甲醇,不溶于乙醇、乙醚有机溶剂及二硫化碳、液体亚硫酸。水溶液是高电离物。强酸。对有机物的反响性弱,其盐类易溶于水(除碱性汞盐外)。其水溶液煮沸时水解为硫酸铵。有毒!不蒸发也不吸湿,在常温下很安稳。能溶于水,水溶液呈酸性。在沸水中水解生成NH+4和HSO-4。
1. Aminosulfonic acid is relatively stable in the normal temperature and dry environment. It only needs to insist on not touching water and not absorbing moisture from solid. Differentiation at high temperature releases toxic gases such as oxides of nitrogen and sulfur. Aminosulfonic acid, its salts and various metal compounds can produce soluble salts. Differentiation at 260 C. Soluble in water, liquid ammonia, slightly soluble in methanol, insoluble in ethanol, ether organic solvents and carbon disulfide, liquid sulfite. Aqueous solutions are highly ionized. Strong acid. The reaction to organic matter is weak, and its salts are soluble in water (except alkaline mercury salts). Its aqueous solution is hydrolyzed to ammonium sulfate when boiling. Toxic! No evaporation, no moisture absorption, very stable at room temperature. It is soluble in water and acidic in water. NH+4 and HSO-4 were synthesized by hydrolysis in boiling water.
2.氨基磺酸在空气中不吸湿,在室温文枯燥环境下能长时间保存。化学性质安稳,其水溶液有较强酸性,对金属有腐蚀作用。
2. Aminosulfonic acid does not absorb moisture in the air and can be stored for a long time at room temperature in dry environment. Its chemical properties are stable, its aqueous solution has strong acidity and corrosive effect on metals.
3.溶解性:溶于水、液氨,微溶于乙醇和甲醇,微溶于丙酮不溶于醚。不溶于有机溶剂。易溶于含氮碱液和液氮;也可溶于含氮的有机试剂如吡啶等;难溶于乙醇和甲醇。在水中能中等程度溶解,与常见非极性溶剂如THF或甲苯等很难混合。
氨基磺酸
3. Solubility: soluble in water, liquid ammonia, slightly soluble in ethanol and methanol, slightly soluble in acetone and insoluble in ether. It is insoluble in organic solvents. It is soluble in nitrogen-containing alkali liquor and liquid nitrogen, or in nitrogen-containing organic reagents such as pyridine, etc. It is insoluble in ethanol and methanol. It can dissolve moderately in water and is difficult to mix with common non-polar solvents such as THF or toluene.
