About ALS Ammonium Sulfate：

Sodium 2-(dodecyl oxygen) ethanesulfonate (SDAO) is an important anionic surfactant with excellent surface activity and wettability. Here are the main features of SDAO:

Surface activity: SDAO has a lower critical micelle concentration (CMC), which can effectively reduce surface tension at lower concentrations and promote wetting, emulsification, dispersion and stabilization.

Solubility: SDAO has good solubility and can be dissolved in water, alcohol, ketone and other solvents to form a transparent solution.

Stability: SDAO has good chemical stability, is not easy to decompose and deteriorate, and can withstand a certain range of acid, base and salt environments.

Biocompatibility: SDAO is less irritating to the skin, low or non-toxic, biodegradable and environmentally friendly.

Simple synthesis: SDAO can be synthesized by a simple chemical reaction; the process is mature, and costs are low.

However, SDAO has some limitations, such as poor foam stability, which may affect the use effect. At the same time, its production and use process may produce environmental problems, such as wastewater, waste gas discharge, and waste residue treatment. Therefore, corresponding environmental protection measures should be taken in the production process and used to strengthen the treatment and recycling of waste to reduce the negative impact on the environment.

Applications of SLI-80 Sodium 2-(dodecanoyloxy)ethanesulfonate:

Industrial cleaning: SDAO is widely used because of its strong wettability and permeability; it can effectively remove oil and impurities. It can be used to clean various equipment and parts, such as mechanical parts, oil tanks, pipelines, etc., especially in petrochemical, automobile manufacturing and other industries. Using SDAO, the cleaning effect and efficiency can be greatly improved, and the cleaning time and labour costs can be reduced.

Cosmetics industry: SDAO is widely used as an emulsifier, stabilizer and thickener in the cosmetics industry. It helps to improve the product's stability, spreadability and permeability and increase its use effect and experience. In cosmetics such as creams, lotions, shampoos, and body washes, SDAO plays an important role as one of the main ingredients.

Pesticides and fertilizers: SDAO is used as a dispersant, wetting agent and stabilizer in pesticides and fertilizers, which helps to improve the uniform dispersity and adhesion of pesticides and fertilizers, increase the absorption of nutrients and control the effect of plants. It can prepare good-performance pesticide and fertilizer suspension agents, is easy to apply, improves the control effect and reduces environmental pollution.

Rubber and plastics industry: SDAO is used as additives such as plasticizers, stabilizers and dispersants in the rubber and plastics industry. It helps to improve the processing performance, stability and quality of the product. Using SDAO, rubber and plastic products' surface gloss and wear resistance can be improved, and their service life can be extended.

Construction industry: SDAO is used in the construction industry as an additive, such as a reducing agent and dispersant for concrete admixtures. It helps improve concrete's fluidity and hardening properties, reduce construction costs and improve engineering quality. Using SDAO can reduce the water consumption of concrete and improve its strength and durability.

Environmental protection: SDAO has application value in wastewater treatment, soil remediation and oil-water separation. It helps to improve the treatment efficiency and separation effect and reduce the emission of pollutants. In wastewater treatment, SDAO can be used as a flocculant and adsorbent to remove harmful substances in water. In soil remediation, SDAO can improve the treatment effect of contaminated soil. In oil-water separation, SDAO can improve the efficiency of oil-water separation and reduce the impact of oil pollution on the environment.

Production Method of SLI-80 Sodium 2-(dodecanoyloxy)ethanesulfonate:

Alkylation reaction: SDAO production usually begins with an alkylation reaction by reacting dodecyl or dodecyl alcohol with ethylene oxide (EO) to form the corresponding alkyl ether. The key to this reaction step is to control the amount of EO and the reaction temperature to ensure that the resulting alkyl ether has the appropriate chain length and purity. Commonly used catalysts are acidic catalysts, such as sulfuric acid or phosphoric acid.

Sulfonation reaction: After forming the alkyl ether, it is necessary to carry out a sulfonation reaction, that is, to introduce sulfonic acid groups on the hydroxyl group of the alkyl ether. The sulfonation reaction needs to be carried out under certain temperature and pressure conditions to promote the reaction and the high yield of the product.

Salinization reaction: After completing the sulfonation reaction, it is necessary to carry out a salinization reaction to neutralize the generated sulfonate with an appropriate amount of base (such as sodium hydroxide or calcium hydroxide) to generate the corresponding salt. The purpose of this step is to convert the product from an acidic state to sodium salt or calcium salt, which is convenient for subsequent separation and purification.

Separation and purification: After the above reaction steps, the product obtained is a mixture, which needs to be separated and purified. Usually, crystallization, filtration, recrystallization and other methods are used for separation and purification to obtain high-purity SDAO products.

In the production process, the reaction conditions and raw material purity need to be strictly controlled to avoid side reactions and the generation of impurities. At the same time, it is also necessary to properly treat and recycle the generated wastewater, gas, and waste residue to reduce environmental pollution and waste of resources.
