氨基磺酸生产的两种制备方法
来源:http://www.jnjrh.com 日期:2019-05-17 发布人:admin
氨基磺酸又称磺酰胺酸、磺胺酸,是一种强酸,1836年由Rose初次制得,能和许多碱性化合物起反响,在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, also known as sulfamic acid and sulfamic acid, is a strong acid. It was first prepared by Rose in 1836. It can react with many alkaline compounds. It can be synthesized by heating it above the melting point (209 C) at atmospheric pressure. It can be further heated to above 260 C. Sulfur trioxide, sulfur dioxide, nitrogen, hydrogen and water are synthesized. It can hydrolyze and produce ammonium bisulfate at room temperature. It can be heated to the boiling point of aqueous solution to produce ammonium sulfate.
氨基磺酸的消费主要有两种方法,一种是以三氧化硫和氨气为原料消费的气相法,一种是以尿素与发烟硫酸为原料消费的液相法。
There are two main ways to consume aminosulfonic acid. One is gas phase method using sulfur trioxide and ammonia as raw materials, and the other is liquid phase method using urea and fuming sulfuric acid as raw materials.
(1)气相法
(1) gas phase method
将气态三氧化硫和氨气直接中止反响生成氨基二磺酸铵,然后参与水中和硫酸中止水解产生氨基磺酸和硫酸铵。将氨基磺酸从母液中析出,经分别、精制、单调即得产品。
氨基磺酸
Gaseous sulfur trioxide and ammonia gas were directly stopped to react to produce ammonium aminodisulfonate, and then participated in water and sulfuric acid to stop hydrolysis to produce sulfamic acid and ammonium sulfate. Amino sulfonic acid is separated from mother liquor and the product is obtained by separation, refining and monotony.
此种方法的大优点是不产生废酸,原料可循环应用,且应用率较高。但在消费中,其转化率较低,对设备腐蚀较重,同时会产生大量的副产硫酸。每消费1t氨基磺酸要副产8t硫酸铵。因此,该方法本钱较高。该种方法的工艺流程为:S03和NH3同时参与到常压反响
The biggest advantage of this method is that it does not produce waste acid, and the raw material can be recycled and applied at a higher rate. However, in consumption, the conversion rate is low, the equipment is corroded heavily, and a large number of by-product sulfuric acid will be produced at the same time. The byproduct of aminosulfonic acid is 8 tons ammonium sulfate per ton of consumption. Therefore, the cost of this method is higher. The process flow of this method is that S03 and NH3 participate in atmospheric pressure response at the same time.
器中,制得氨基二磺酸铵,氨基二磺酸铵在H2S04的作用下水解、结晶、单调即可得废品。
Ammonium aminodisulfonate is prepared in the reactor. Waste products can be obtained by hydrolysis, crystallization and monotony of ammonium aminodisulfonate under the action of H2S04.
(2)液相法
(2) liquid phase method
将尿素与发烟硫酸在40 - 70℃时中止磺化反响生成氨基磺酸粗品,然后用水处置结晶,得氨基磺酸精品。
The sulfonation reaction of urea and fuming sulfuric acid was stopped at 40 - 70 (?) C to produce crude sulfamic acid, and then the refined sulfamic acid was obtained by treating and crystallizing with water.
液相法消费的特性是:在常压下中止,产生的废酸量少,废气以C02为主,对环境影响小。其工艺流程为:尿素和发烟硫酸参与磺化反响器中,反响一段时间后过滤、重结晶、单调即得废品。
The characteristics of liquid phase consumption are: stop at atmospheric pressure, produce less waste acid, C02 is the main waste gas, and have little impact on the environment. The process flow is: urea and fuming sulfuric acid participate in the sulfonation reactor, after a period of reaction, filter, recrystallization, monotonous waste products.
