无水对氨基苯磺酸 化学试剂、在常温枯燥的环境中,氨基磺酸比拟稳定,只需坚持不与水接触,固体的不吸湿。在高温时合成,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。
Anhydrous p-Aminobenzene Sulfonic Acid Chemical reagent, in normal temperature and dry environment, aminobenzene sulfonic acid is comparatively stable, only insist on not contacting with water, solid does not absorb moisture. It is synthesized at high temperature and emits toxic gases such as oxides of nitrogen and sulfur. Aminosulfonic acid, its salts and a variety of metal compounds can produce soluble salts.
℃时合成。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!不挥发也不吸湿,在常温下很稳定。能溶于水,水溶液呈酸性。
It is synthesized at 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! It is not volatile or hygroscopic and stable at room temperature. It is soluble in water and acidic in water.
在沸水中水解生成NH+4和HSO-4。
NH+4 and HSO-4 were synthesized by hydrolysis in boiling water.
2、基磺酸在空气中不吸湿,在室温和枯燥环境下能长期保管。化学性质稳定,其水溶液有较强酸性,对金属有腐蚀作用。
氨基磺酸
2. Sulfonic acid does not absorb moisture in the air and can be stored in room temperature and dry environment for a long time. Its chemical properties are stable, its aqueous solution has strong acidity and corrosive effect on metals.
3、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。在水中能中等水平溶解,与常见非极性溶剂如THF或甲苯等很难混合。
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.
