氨基磺酸与硫酸的生产方式一样吗?
来源:http://www.jnjrh.com 日期:2019-06-28 发布人:admin
氨基磺酸与水反响生成的氨基磺酸水溶液,具有与盐酸、硫酸同等等的强酸性,故别名又叫固体硫酸,具有不挥发、无臭味和对人体毒性极小的特性,所以能够容易远途运输,现场配置氨基磺酸清洗剂,用处于水处置化学清洗、电镀抛光、消毒漂白等范畴。
Amino sulfonic acid water solution produced by reaction of amino sulfonic acid and water has strong acidity like hydrochloric acid and sulfuric acid, so its nickname is solid sulfuric acid. It has the characteristics of non-volatile, odorless and minimal toxicity to human body, so it can be easily transported over long distances. Amino sulfonic acid cleaning agent is deployed on the spot and used in the fields of chemical cleaning, electroplating polishing, disinfection and bleaching of water disposal.
氨基磺酸消费厂家引见:氨基磺酸是一种强酸,能和许多碱性化合物起反响,常压下将其加热至熔点以上(209℃)开端合成,继续加热至260℃以上,合成为三氧化硫、二氧化硫、氮、氢和水,能水解,常温下,生成硫酸氢铵,加热至水溶液的沸点,生成硫酸铵。
Aminosulfonic acid is a strong acid that reacts with many alkaline compounds. It is heated to above the melting point (209 C) at normal pressure and then synthesized to sulfur trioxide, sulfur dioxide, nitrogen, hydrogen and water at 260 C. Ammonium bisulfate can be hydrolyzed to form ammonium bisulfate at normal temperature and heated to the boiling point of aqueous solution to form ammonium sulfate.
氨基磺酸固然别名叫固体硫酸,但却不能替代硫酸挡硫酸用,由于硫酸是液体,稀硫酸能降低氨基磺酸的溶解度,所以在工业循环水系统中,可用氨基磺酸替代浓硫酸运用来降低循环水水质的总碱度,而且条件是氨不发作反响,其他状况下,氨基磺酸是不能替代硫酸挡硫酸用的。
Aminosulfonic acid, although nicknamed solid sulfuric acid, can not replace sulfuric acid as a barrier to sulfuric acid. Because sulfuric acid is liquid and dilute sulfuric acid can reduce the solubility of sulfamic acid, sulfamic acid can be used instead of concentrated sulfuric acid in industrial circulating water system to reduce the total alkalinity of circulating water quality, and the condition is that ammonia does not react. In other cases, sulfamic acid can not replace sulfur. Sulfuric acid.
氨基磺酸的消费办法与硫酸有关:
The consumption of aminosulfonic acid is related to sulfuric acid.
氨基磺酸
1、以尿素为原料,与发烟硫酸作用,反响在45℃以下停止,由于放热,应留意冷却,反响完毕后,坚持低温数小时,然后加热至 80~90℃,蒸出多余的三氧化硫,过滤、洗濯,在水中重结晶制得,在参加尿素时,应冉冉参加,防止因放热过激使温度升高。
1. With urea as raw material and fuming sulfuric acid, the reaction stops below 45 C. Because of exothermic reaction, we should pay attention to cooling. After the reaction is finished, we should keep low temperature for several hours, then heat it to 80-90 C. The excess sulfur trioxide is evaporated, filtered and washed. It is recrystallized in water. When urea is added, we should take part in it slowly to prevent the temperature from rising due to exothermic stress.
2、液氨和硫酸停止气相反响,然后水解,可制得。副产硫酸铵及硫酸。此法反响条件苛刻,设备材质请求高,纯度及收率均低,只合适消费粗制。
2. Liquid ammonia and sulfuric acid stop gas-to-gas reaction and hydrolyze to produce. By-product ammonium sulfate and sulfuric acid. This method has harsh reaction conditions, high material requirements, low purity and yield, and is only suitable for rough consumption.
3、三氧化硫和液氨反响,生成氨基亚硫酸氨,进一步与硫酸作用,可制得。
3. Sulphur trioxide and liquid ammonia react to form ammonia aminosulfite, which can be further reacted with sulfuric acid.
氨基磺酸用处:
Aminosulfonic acid use:
氨基磺酸是固体,具有储存、运输便当,容易配制等优点,特别适用远途运用,所以可现场配置氨基磺酸清洗剂,用处于清洗锅炉、冷凝器、换热器、夹套及化工管道,肃清啤酒厂用的玻璃衬里贮罐、锅、启齿啤酒冷却器、啤酒桶上的垢层,清洗搪瓷厂的蒸发器,以及造纸厂的设备等;在空调方面可除去冷却系统、蒸发冷凝器的铁锈、水垢;肃清海水蒸发器(蒸馏设备)、换热器和盐水加热器内的海藻、水垢;清洗铜壶、散热器、餐具洗濯机理、银器、抽水马桶、瓷砖、食品和奶酷加工设备的水垢;肃清堆积在蒸煮器上的蛋白质以及鲜肉、蔬菜、奶酪加工厂中运用的消毒吕上的堆积物,以及在鲜肉、家禽、兔、蛋加工企业上用作酸性清洗剂。
Aminosulfonic acid is a solid, with the advantages of convenient storage, transportation and easy preparation. It is especially suitable for long-distance application. Therefore, it can be disposed of on-site cleaning agent, cleaning boilers, condensers, heat exchangers, jackets and chemical pipelines, cleaning glass-lined tanks, pots, toothed beer coolers, beer drums, cleaning evaporators in enamel factories. As well as the equipment of paper mill, it can remove the rust and scale of cooling system and evaporative condenser in air-conditioning; remove seaweed and scale in seawater evaporator (distillation equipment), heat exchanger and brine heater; clean copper kettle, radiator, washing mechanism of tableware, silver, toilet, ceramic tile, food and milk processing equipment; remove the scale accumulated on the steamer. Protein and the accumulation of disinfectant Lu used in fresh meat, vegetable and cheese processing plants, as well as acid detergent used in fresh meat, poultry, rabbit and egg processing enterprises.
