High quality Ammonium hydroxide cas 1336-21-6

Ammonia (NH3[aq]) is often referred to as Ammonian water. It refers to an aqueous ammonia solution that has a strong pungent odor and is slightly alkaline. In ammonia water, ammonia molecules undergo weak hydrolysis to produce hydroxide ions and ammonium ions. The “ammonium hydroxide” does not actually exist, but is only a description of the ions in the aqueous ammonia solution and cannot be separated from the solution. The ionization of ammonia in water can be expressed as:
NH3·H2O→NH+ 4+OH−
The reaction equilibrium constant Kb = 1.8×10−5. The pH of 1M ammonia is 11.63, and approximately 0.42% of NH3 becomes NH4+. Ammonia is a common source of ammonia in the laboratory. It can react with solutions containing copper (II) ions to generate dark blue complexes. It can also be used to configure analytical reagents such as silver ammonia solution.

production method
Method 1. Using the bottle of liquid ammonia as raw material, after washing with 1% potassium permanganate, 5% sodium hydroxide suspension and two pure water bottles, dissolve in the high-purity water in the absorption plane, and the absorption bottle is cooled with ice water. . Control the ammonia flow rate, careful operation can reach high purity level. Pure distilled water is used to administer reagent ammonia.
Method 2. Using industrial ammonia as raw material, add appropriate amount of potassium permanganate (plus 15 g of potassium permanganate per 15 kg of ammonia) to remove all reducing substances. Then add dropwise to 9
In distilled water at 8 oC, the evaporated ammonia is washed with distilled water and a saturated solution of cesium hydroxide in order, and an empty bottle (to prevent the backflow of ammonia) is poured into it. After entering the absorption bottle containing distilled water, the absorption bottle is cooled with water. When the relative density of hand sanitizer is up to standard, other indicators can be tested. To improve the purity of the absorbed ammonia, chemical ammonia can be used as a raw material, and the level of auxiliary reagents can be increased accordingly.

USED 

Used as an analytical reagent, such as neutralizer, masking agent, precipitant, and buffer solution. Also used as a cleaning agent, alkaloid lixivium. For the pharmaceutical industry, yarn cover industry, blueprints, agricultural fertilization and so on.

Product expansion

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.

2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.

3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.

4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.

5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
