氨基磺酸的生产原料成本及特性为发展带来哪些作用?
来源:http://www.jnjrh.com 日期:2019-09-08 发布人:admin
氨基磺酸又称磺酞胺酸,其化学式为NHZ一0一 )O ‘11 卜s一OH,它是一种基本有机化工原料,由于其性质 优良用途广泛,日益受到重视。在国外,氨基磺酸的 ‘需求量越来越大。在我国,只有少量生产,且质量较 差,价格昂贵,影响到它在生产上的应用,但在一些 ,引进的工艺生产中需要氨基磺酸配套,氮基礴酸的性能 ;氨基磺酸HSO。
Aminosulfonic acid, also known as sulfaphthalamic acid, whose chemical formula is NHZ-101) O'11Boos-OH, is a basic organic chemical raw material. It has attracted increasing attention because of its excellent properties and wide applications. Overseas, the demand for aminosulfonic acid is increasing. In our country, only a small amount of production, poor quality and high price affect its application in production, but in some imported process production, it needs amino sulfonic acid matching, the performance of nitrogen-based hyaluronic acid, HSO of amino sulfonic acid.
NHZ是一种白色结晶体,无臭, 、不挥发,’示吸湿,可燃,低毒。干燥的产品性质稳 }定,可以保持几年不变化,可作标准试剂。 ;氨基磺酸比重2.126。熔点205℃(209℃开始分 亡解)。260℃时分解为502、503、NZ、HZo及其它微量产物。氨基磺酸的生成热为685.9千焦耳/摩尔。 氨基磺酸能溶于水、氨水,甲酞胺、微溶甲醇、乙醇等有机溶剂。氨基磺酸在水溶液中电离度很大,它的酸性比甲酸、磷酸、草酸强,可与硫酸、盐酸及硝酸相提并论。
NHZ is a white crystalline, odorless, non-volatile,'indicating hygroscopicity, flammability and low toxicity. Dry products have stable properties and can remain unchanged for several years. They can be used as standard reagents. The specific gravity of aminosulfonic acid was 2.126. The melting point is 205 ("209') and begins to decompose. It was decomposed into 502, 503, NZ, HZo and other trace products at 260 ~C. The heat of formation of aminosulfonic acid is 685.9 kJ/mol. Aminosulfonic acid can be dissolved in water, ammonia water, methylphthalide amine, slightly soluble methanol, ethanol and other organic solvents. Aminosulfonic acid is highly ionized in aqueous solution. Its acidity is stronger than formic acid, phosphoric acid and oxalic acid. It can be compared with sulfuric acid, hydrochloric acid and nitric acid.
氨基磺酸
氨基磺酸(NHZSO3H)为白色结晶性粉末,可以长期保存,能作标准试剂。它具有不挥发、不吸湿、无气味、毒性低等特性,极易溶于水。水溶液呈酸性,仅次于硝酸、硫酸、盐酸。 我国生产该产品的历史不到十年。氨基磺酸的应用范围相当广,由它出发,可以衍生出不少产品,是一个很有开发前途的化学新产品。 根据我国国情及今后发展需求,应用方面的开拓,应致力于清洗、漂白、阻燃、电镀以及磺化等领域,就华南、华中地区实际情况,则可侧重向清洗、磺化、电镀等方向发展和开拓。
Aminosulfonic acid (NHZSO3H) is a white crystalline powder, which can be preserved for a long time and used as a standard reagent. It is non-volatile, non-hygroscopic, odorless, low toxicity and other characteristics, very soluble in water. The aqueous solution is acidic, second only to nitric acid, sulfuric acid and hydrochloric acid. Our country has been producing this product for less than ten years. Aminosulfonic acid has a wide range of applications. Starting from it, many products can be derived. It is a promising new chemical product. According to China's national conditions and future development needs, application development should be devoted to cleaning, bleaching, flame retardant, plating and sulfonation. In view of the actual situation in South and Central China, we can focus on cleaning, sulfonation and plating.
氨基磺酸是原料便宜、用途广泛的精细化工产品。在国外氨基磺酸广泛用作分析基准试剂、低腐蚀金属清洗剂、无机阻燃剂、pH调节剂、纸浆漂白、印染工艺改进助剂以及酸性洗涤剂、甜味剂和氨基磺酸盐类产品合成的基本原料。 .近年来国内有关行业已开始注意氨基磺酸的工业应用推广,取得了很好的效果。由于该产品性能极稳定,存运方便,并为低腐蚀性强酸产品,‘其发展前景比较广阔。
Aminosulfonic acid is a fine chemical product with cheap raw materials and wide uses. Aminosulfonic acid is widely used abroad as analytical benchmark reagent, high-efficiency and low-corrosion metal cleaner, inorganic flame retardant, pH regulator, pulp bleaching, printing and dyeing process improvement additives, as well as basic materials for acid detergent, sweetener and sulfamate product synthesis. In recent years, the relevant industries in China have begun to pay attention to the industrial application and promotion of sulfamic acid, and achieved good results. Because the product has very stable performance, convenient storage and is a low corrosive strong acid product,'Its development prospects are relatively broad.
