Description of ALS Ammonium Lauryl Sulfate ：

Chemical structure: dodecyl ammonium sulfate combines dodecyl (C12H25) with ammonium sulfate (NH4HSO4). Its molecular formula is C12H25SO4NH4.

Physical state: Ammonium lauryl sulfate is a white or light yellow solid soluble in water.

Solubility: Ammonium dodecyl sulfate has good water solubility, which increases with an increase in temperature. 

pH sensitivity: Ammonium dodecyl sulfate dissociates into cations and anions in water, making the solution acidic. Its dissociation constant (pKa) depends on temperature and concentration but is usually between 4.5 and 5.0.

Surface activity: Due to its unique hydrophilic and hydrophobic structure, ammonium lauryl sulfate has surface activities such as reducing surface tension, wetting, emulsification, decontamination and foaming. These properties make it widely used in cleaning agents, cosmetics, pesticides, the petro, and textile industries.

Stability: Ammonium dodecyl sulfate is relatively stable under normal storage conditions, but decomposition may occur under high temperature, strong acid or base conditions.

Biodegradability: Ammonium lauryl sulfate has a certain biodegradability in the natural environment, but it may have negative effects in cases of strong pollution, such as biotoxicity or eutrophication.

Toxicity: Ammonium lauryl sulfate irritates the skin and eyes, and inhalation or ingestion may cause discomfort or poisoning. Therefore, appropriate personal protection measures should be taken during use.

Reactivity with other substances: Ammonium lauryl sulfate can react with various ions and other surfactants to form precipitates, micelles or associations. Understanding its reactivity helps to predict its performance in different applications.

Cosmetics industry: Due to its good wetting, emulsifying and decontamination ability, ammonium lauryl sulfate is widely used as an emulsifier, stabilizer and detergent in the cosmetics industry. It can effectively improve the stability of cosmetics, improve the texture of products, and enhance the skin's absorption of cosmetics. Ammonium dodecyl sulfate can be found in cosmetics such as face creams, lotions and lipsticks.

Textile industry: In the textile industry, ammonium lauryl sulfate is mainly used as a dispersant for dyes and a softener for textiles. It can effectively improve the dispersion of the dye so that it can better penetrate the fiber, thus improving the dyeing effect. At the same time, it can also improve textiles' softness, elasticity and wrinkle resistance, improving the comfort and durability of products.

Petroleum industry: In the petroleum industry, ammonium lauryl sulfate is mainly used as a drilling fluid and oil recovery additive in oil fields. At the same time, it can also be used as an oil recovery additive to improve oil recovery efficiency and production.

Agriculture: In agriculture, ammonium lauryl sulfate can be used as an additive to pesticides and a plant growth regulator. It can improve the adhesion and permeability of pesticides and enhance their effect. At the same time, it can also promote plant growth and development, improving crop yield and quality.

Detergent Industry: Ammonium lauryl sulfate is widely used in the detergent industry as an ingredient in products such as detergents, hand sanitizers and cleaners.  At the same time, it can give cleaning products good foam and stability and improve the user's experience.

Plastics industry: Ammonium lauryl sulfate can be used as additives such as plasticizers and stabilizers in the plastics industry. It can improve the processing performance and stability of plastics and extend the service life of products. At the same time, it can also improve the surface properties of plastics, making it easier to paint and print.

Leather industry: In the leather industry, ammonium lauryl sulfate can be used as an additive in leather finishing and dyeing agents. It can improve the dyeing effect and finish quality of the leather, making it smoother, softer, and durable. At the same time, it can also improve the leather's water and wrinkle resistance and the product's practicality and beauty.

Water treatment industry: In sewage treatment and water purification, ammonium dodecyl sulfate can be used as additives such as flocculants and dispersants. At the same time, it can also be used as a flocculant so that the suspended matter and impurities in the water form a large fluffy precipitation, which is easy to separate and filter.

Ink industry: In ink manufacturing and printing, ammonium dodecyl sulfate can be used as a wetting and leveling agent for ink. It can improve the wettability and leveling of the ink, making the print clearer, smooth and flat. At the same time, it can also enhance the adhesion and wear resistance of the ink and improve the durability and preservation of the printed matter.

Production Method of ALS Ammonium Lauryl Sulfate:

Alcoholysis: Alcoholysis is one of the main methods for producing ammonium dodecyl sulfate. Using ethanol and methyl chloride as raw materials, methoxyethanol was produced by esterification reaction, and then ammonium dodecyl sulfate was obtained by hydrolysis reaction. The specific steps are as follows:

(1) Esterification reaction: ethanol and methyl chloride are esterified under the action of a catalyst to produce methoxyethanol. This step is a reversible reaction, and the reaction temperature and pressure need to be controlled to make the reaction proceed in the direction of the formation of methoxyethanol.

(2) Hydrolysis reaction: methoxyethanol and water are hydrolyzed under the action of a catalyst to generate ammonium dodecyl sulfate. Hydrolysis reaction needs to control the reaction temperature and pressure, and attention must be paid to prevent the occurrence of side reactions.

(3) Rectification: distillation of the hydrolysis reaction products to separate ammonium dodecyl sulfate. The rectification process aims to remove by-products and impurities and obtain high-purity ammonium dodecyl sulfate.

Ethylene process: Another method for producing ammonium lauryl sulfate is the ethylene process. Ethylene and ethylene oxide were used as raw materials; an addition reaction formed ethylene glycol, and a substitution reaction with methyl chloride obtained ammonium dodecyl sulfate. The specific steps are as follows:

(1) Addition reaction: ethylene and ethylene oxide are added under the action of a catalyst to produce ethylene glycol. The addition reaction must be carried out under certain temperature and pressure conditions to control the reaction speed and selectivity.

(2) Substitution reaction: ethylene glycol and methylene chloride are substituted under the action of a catalyst to generate ammonium dodecyl sulfate. The conditions and selective control of the substitution reaction are similar to that of the addition reaction, but attention should be paid to preventing the occurrence of side reactions.

(3) Rectification: distillation of the product of the substitution reaction to separate ammonium dodecyl sulfate. The rectification process aims to remove by-products and impurities and obtain high-purity ammonium dodecyl sulfate.

Transesterification: Transesterification is another feasible method for producing ammonium dodecyl sulfate. The method uses methyl ester and ethanol to produce ammonium dodecyl sulfate by transesterification reaction. The specific steps are as follows:

(1) Transesterification reaction: methyl ester and ethanol are transesterification reactions under the action of a catalyst to produce ammonium dodecyl sulfate. Transesterification reaction must be carried out under certain temperature and pressure conditions, and the reaction speed and selectivity are controlled.

(2) Rectification: distillation of the transesterification reaction products to separate ammonium dodecyl sulfate. The rectification process aims to remove by-products and impurities and obtain high-purity ammonium dodecyl sulfate.
