指标称号劣等品 一等品 合格品外观 无色或白色结晶 无色或白色结晶 白色粉末氨基磺酸的质量分数/%≥ 99.8 99.0 95.0水不溶物/%≤ 0.02 — —硫酸盐/%≤ 0.4 1.0 —铁(Fe)含量/%≤ 0.01 0.01 —枯燥失量/%≤ 0.2 — — 氨基磺酸是重要的精密化工产品,普遍应用于金属和陶瓷制造的多种工业设备和民用清洗剂、石油并处置剂和清洗剂、电镀工业用剂电化学抛光用剂、沥青乳化剂、蚀刻剂、染料医药及颜料工业用磺化剂、染色用剂、高效漂白剂、纤维、纸张用阻燃剂、柔软剂、树脂交联促进剂、除草剂、防枯剂以及规范剖析试剂等各个范畴中。氨基磺酸能够制成极纯的常温时稳定的结晶体,其水溶液具有与盐酸、硫酸同等的强酸性,别名固体硫酸。不挥发,不吸湿,对人身毒性极小,但皮肤不能长时间与氨基磺酸接触,更不能进入眼睛。氨基磺酸消费工艺过程简单,反响较容易控制,原料及设备都较容易处理,废水也容易处置,副产物能够有效应用。该产品能够替代硫酸,其包装、储存、运输都很便当。
Indicator Title Grade I Qualified Product Appearance Colorless or White Crystal Colorless or White Crystal White Powder Aminosulfonic Acid mass fraction /%> 99.8 99.0 95.0 Water insoluble /%= 0.02 - Sulfate /%= 0.41.0 - Iron (Fe) content /%= 0.01 - Dry loss /%= 0.2 - Aminosulfonic acid is an important precision chemical product, which is widely used in metals and ceramics. Manufactured various industrial equipment and civil cleaning agents, petroleum and disposal agents and cleaning agents, electrochemical polishing agents for electroplating industry, asphalt emulsifiers, etchants, sulfonating agents for dyestuffs, pharmaceuticals and pigments industry, dyeing agents, high-efficiency bleaching agents, flame retardants for fibers, paper, softeners, resin cross-linking promoters, herbicides, withering inhibitors and standard analytical reagents, etc. Category. Aminosulfonic acid can be prepared into very pure crystals at room temperature. Its aqueous solution has the same strong acidity as hydrochloric acid and sulfuric acid, alias solid sulfuric acid. No volatilization, no moisture absorption, very little toxicity to human body, but the skin can not be long contact with Aminosulfonic acid, let alone into the eyes. Aminosulfonic acid consumption process is simple, the reaction is easy to control, raw materials and equipment are easy to deal with, wastewater is easy to deal with, by-products can be effectively applied. The product can replace sulphuric acid, and its packaging, storage and transportation are convenient.
氨基磺酸是具有氨基和磺酸基的双官能团物质,能停止与之有关的许多化学反响.
Aminosulfonic acid is a bifunctional substance with amino and sulfonic groups, which can stop many chemical reactions related to it.
1、合成反响:氨基磺酸在常温度下很稳定,加热到209度时开端合成。2HSO3NH2——SO2+SO3+N2+2H2+H2O
氨基磺酸
1. Synthetic response: Aminosulfonic acid is stable at normal temperature, and begins to synthesize when heated to 209 degrees. 2HSO3NH2-SO2+SO3+N2+2H2+H2O
2、与金属反响 氨基磺酸能与金属反响,生成盐和氢气,但与较生动金属反响,氨基的一个氢可被取代,生成双金属盐。2HSO3NH2+Zn——Zn(SO3NH2)2+H2HSO3NH2+2Na——NaSO3NHNa+H2
2. Aminosulfonic acid reacts with metals to form salts and hydrogen, but reacts with more vivid metals to form bimetallic salts. 2HSO3NH2+Zn-Zn(SO3NH2)2+H2HSO3NH2+2Na-NaSO3NHNa+H2
3、与金属氧化物、氢氧化物和盐反响。2HSO3NH2+FeO——Fe(SO3NH2)2+H2O
3. Reaction with metal oxides, hydroxides and salts. 2HSO3NH2+FeO-Fe(SO3NH2)2+H2O
4、与亚硝酸盐和硝酸盐反响 氨基磺酸能被亚硝酸盐和硝酸盐疾速氧化。
4. Aminosulfonic acid, which reacts with nitrite and nitrate, can be rapidly oxidized by nitrite and nitrate.
5、与氧化剂反响 氨基磺酸能被次氯酸钠氧化,但不能被、和三氯化铁氧化。
5. Aminosulfonic acid reacting with oxidant can be oxidized by sodium hypochlorite, but not by ferric chloride and ferric chloride.
6、与醇和酚反响HSO3NH2+ROH——ROSO2ONH4HSO3NH2+C6H5OH——C6H5OSO2ONH4
6. Reaction with alcohols and phenols HSO3NH2+ROH-ROSO2ONH4HSO3NH2+C6H5OH-C6H5OSO2 ONH4
7、与胺和酰胺反响HSO3NH2+RNH2—— RNH3SO3NH2HSO3NH2+C6H5CONH2——C6H5CONHSO3NH4
7. Reaction with Amines and Amides HSO3NH2+RNH2-RNH3SO3NH2HSO3NH2+C6H5CONH2-C6H5CONHSO3NH4
8、生成络合物氨基磺酸与硫酸钠反响,生成氨基磺酸络合物。6HSO3NH2+5Na2SO4——6HSO3NH2*5Na2SO4*15H2O
8. The formation of complex sulfamic acid reacts with sodium sulfate to form sulfamic acid complex. 6HSO3NH2+5Na2SO4-6HSO3NH2*5Na2SO4*15H2O
9、水解反响氨基磺酸水溶液加热至60度以上时,将水解成硫酸盐HSO3NH2+H2O——NH4HSO4 自从氨基磺酸工业化消费以来,由于应用范围不时扩展,产品产量也相应增长。
9. When the water solution of hydrolytic reaction aminosulfonic acid is heated to above 60 degrees, it will be hydrolyzed into sulfate HSO3NH2+H2O-NH4HSO4. Since the industrial consumption of aminosulfonic acid, the product output has increased correspondingly due to the expansion of its application range from time to time.
