氨基磺酸的分子式为nh2s03h。市售商品为白色粉末,在常温下,只需坚持枯燥不与水接触,固体的氨基磺酸不吸湿,比拟稳定。 氨基磺酸的水溶液具有与盐酸、硫酸同等等的强酸性,故别名又叫固体硫酸,它具有不挥发、无臭味和对人体毒性极小的特性。 氨基磺酸水溶液对铁的腐蚀产物作用较慢,可添加一些氯化钠,使之迟缓产生盐酸,从而有效地溶解铁垢。 氨基磺酸水溶液可去除铁、钢、铜、不锈钢等资料制造的设备外表的水垢和腐蚀产物。另外,它还是独一可用作镀锌金属外表清洗的酸。 应用氨基磺酸水溶液停止清洗时,温度普通控制在不超越66℃(以防氨基磺酸合成),浓度不超越10%。
The molecular formula of aminosulfonic acid is nh2s03h. The commercial product is white powder. At room temperature, only insist on dryness and not contact with water. Solid sulfamic acid does not absorb moisture and is comparatively stable. Aminosulfonic acid aqueous solution has the same strong acidity as hydrochloric acid and sulfuric acid, so it is also called solid sulfuric acid. It has the characteristics of non-volatile, odorless and minimal toxicity to human body. Aminosulfonic acid aqueous solution has a slow effect on the corrosion products of iron. Some sodium chloride can be added to slow the production of hydrochloric acid, thus effectively dissolving iron scale. Aminosulfonic acid aqueous solution can remove scale and corrosion products on the surface of equipment made of iron, steel, copper and stainless steel. In addition, it is the only acid that can be used for cleaning the surface of galvanized metal. When the washing is stopped by using sulfamic acid aqueous solution, the temperature is generally controlled not to exceed 66 C (in order to prevent the synthesis of sulfamic acid), and the concentration is not more than 10%.
氨是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。
Ammonia is an important precise chemical product. It is widely used in many industrial equipments and civil cleaning agents for metal and ceramics manufacturing, petroleum and disposal agents and cleaning agents, electrochemical polishing agents for electroplating industry, asphalt emulsifiers, etching agents, sulfonating agents for dyes, pharmaceuticals and pigments industry, dyeing agents and efficient bleaching agents. In the fields of agent, fiber, paper flame retardant, softener, resin cross-linking accelerator, herbicide, withered-proof agent and standard analytical reagent, etc.
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。
氨基磺酸
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.
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。日本在1965年年产量为1.4万吨,1980年售价每公斤为140~160日元。日本消费厂有富士的日产化学公司,年产7.2千吨;大阪的大喜产业公司,年产3千吨。美国年产量为5万吨,在1984年每100磅售价为38~41美圆。我国消费氨基磺酸厂有无锡硫酸厂,扩建后的消费才能为年产600吨,上海硫酸厂,年消费才能为1000吨。售价每吨为2800~3000元。
Since the industrial consumption of aminosulfonic acid, the output of products has increased correspondingly due to the expansion of its application range from time to time. Japan produced 14,000 tons in 1965 and sold at 140-160 yen per kilogram in 1980. Japanese consumer factories have Fuji Nissan Chemical Company, with an annual output of 7.2 thousand tons; Osaka Daxi Industrial Company, with an annual output of 3 thousand tons. The annual output of the United States is 50,000 tons. In 1984, the price was 38-41 dollars per 100 pounds. There are Wuxi Sulphuric Acid Plant in China. After expansion, the annual consumption can reach 600 tons, and Shanghai Sulphuric Acid Plant can reach 1000 tons. The price is 2800-3000 yuan per ton.

Properties of Aminosulfonic Acid
分子量 97.09   熔点℃ 205   应用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,在水中溶解高度不析出沉淀而对金属的腐蚀小的特性,作为清洗剂可除去铁、钢、铜、不锈钢、铅、陶瓷等制造的机器、设备中在运用过程中生成的铁锈和水垢。
Molecular Weight 97.09 Melting Point Temperature 205 Application of sulfamic acid and its salts and a variety of metal compounds can produce soluble salts, soluble in water without precipitation and little corrosion to metals. As a cleaning agent, it can remove iron, steel, copper, stainless steel, lead, ceramics and other manufacturing machinery and equipment in use. Rust and scale formed during the process.
氨基磺酸作为清洗剂,由于它是固体,具有储存、运输便当,容易配制等很多优点,特别适用远途运用。
Aminosulfonic acid as a cleaning agent, because it is solid, has many advantages such as convenient storage, transportation, easy preparation and so on, especially suitable for long-distance use.
将氨基磺酸溶液注入碳酸盐岩产油层。由于氨基磺酸容易和油层岩石起反响,能防止反响生成盐的堆积,处置费用比用盐酸略高些,但石油产量倍增。美国用羟基乙酸钾48.5%,氨基磺酸3.4%。润湿剂0.1—3%的水溶液清洗油井套管中的石膏垢层,处置时间约30小时,镀镍废液中回收时是用阳离子交流树脂吸附处置然后用氨基磺酸清洗树脂,使被吸附的解吸出来,树脂取得再生。例如处置400ppmni的电镀废液,用150克/升的氨基磺酸50ml,回收的(nh2so3)2112克/升,niso4148克/升。在镀镍部件修复时需求镍上镀镍,在其阳极处置时可用100克/升的氨基磺酸处置。在镀镍前的镀镍外表要用0.003~0.1克分子的氨基磺酸溶液清洗
Aminosulfonic acid solution is injected into carbonate reservoir. Because sulfamic acid is easy to react with reservoir rocks and can prevent the accumulation of salt generated by the reaction, the cost of disposal is slightly higher than that of hydrochloric acid, but the oil production is doubled. Potassium glycoacetate 48.5% and aminosulfonic acid 3.4% were used in the United States. The wetting agent 0.1-3% water solution cleans the gypsum scale layer in the casing of oil well. The disposal time is about 30 hours. When the nickel plating waste liquid is recovered, the resin is adsorbed and disposed by cation exchange resin and then cleaned by Aminosulfonic acid, so that the adsorbed resin is desorbed and regenerated. For example, 400 ppmni electroplating waste solution is disposed of with 150 g/l sulfamic acid 50ml, recycled (nh2so3) 2112 g/l and niso4148 g/l. Nickel plating on nickel is required for repairing nickel plated parts, and 100g/L sulfamic acid can be used for anodic disposal. The appearance of nickel plating before nickel plating should be cleaned with 0.003-0.1 g molecule sulfamic acid solution.
