Description of Semi-branched C11-13 alcohol ether sulfate:

Water solubility: Semi-branched-chain C11-13 alcohol ether sulfate is very water soluble and can form a transparent solution in water, a property that makes it excellent in many applications.

Interfacial activity: Due to its branched-chain molecular structure, semi-branched-chain C11-13 alcohol ether sulfate has strong interfacial activity. This means that it can form a molecular film at the oil-water interface, reducing surface tension and making it easier for oil, dust, and other substances to be washed away by water.

Foaming properties: The substance foams effectively at low concentrations, which is important for many washing and cleaning applications. The resulting foam is stable and abundant, and can better adsorb and remove stains.

Mild: Compared with traditional linear alkyl benzene sulfonate, semi-branched chain C11-13 alcohol ether sulfate is milder. This means it is less irritating to the skin and eyes and safer to use.

Biodegradability: Semi-branched-chain C11-13 alcohol ether sulfate is easily degraded by microorganisms, which makes it an environmentally friendly surfactant.

Stability: The substance is stable over a wide range of pH values and is not sensitive to hard water, which means that it maintains good performance under a variety of conditions.

Petroleum industry: Semi-branched C11-13 alcohol ether sulfate plays an important role in petroleum extraction and processing. As a wetting agent, emulsifier, and foaming agent, it can improve recovery and processing efficiency. Improving the wettability and emulsification stability of the oil-water interface helps improve the oil recovery efficiency and the efficiency of oil production equipment. In addition, semi-branched-chain C11-13 alcohol ether sulfate has also been widely used in oil cracking, heavy oil emulsification, and other fields.

Textile industry: semi-branched chain C11-13 alcohol ether sulfate is mainly used in the textile industry for the production of dyes and printing and dyeing auxiliaries. As a wetting agent and dispersant of dyes, it can improve the uniform dispersion and wettability of dyes on fibers, thereby improving the dyeing quality and printing effect. This helps achieve a more vibrant, long-lasting color effect and reduces the appearance of chromatic aberrations and spots. In addition, semi-branched chain C11-13 alcohol ether sulfate is also widely used in the production of textile finishing and softening agents.

Agricultural field: In the agricultural field, semi-branched chain C11-13 alcohol ether sulfate is used as an emulsifier and dispersant of pesticides to improve the dispersion and wettability of pesticides, thereby improving the adhesion and permeability of pesticides, which is conducive to the uniform application of pesticides and plant absorption. This helps to improve the control effect of pesticides and reduce the amount of pesticides, reducing the negative impact on the environment and crops.

Production Method of Semi-branched Alcohol Ether Sulfate C11-13:

Raw material preparation: First of all, it is necessary to prepare the alcohol raw materials of C11-13, which can be natural oil or petrochemical raw materials through esterification, alcoholysis, and other reactions. At the same time, it is also necessary to prepare an appropriate amount of sulfuric acid as a reactant.

Etherification reaction: the alcohol raw material of C11-13 is mixed with an appropriate amount of sulfuric acid, and the etherification reaction is carried out at a certain temperature and pressure. Sulfuric acid acts as a catalyst to promote etherification between alcohol molecules. During the reaction process, it is necessary to control the temperature and pressure to ensure the smooth progress of the reaction.

Neutralization reaction: After completing the etherification reaction, the resulting sulfate mixture is neutralized with a base to neutralize excess sulfuric acid. Through a neutralization reaction, the intermediate product containing sulfate can be obtained.

Oxidation reaction: The sulfate intermediate product obtained in the previous step is oxidized under the action of air or oxygen to generate the corresponding sulfate. This step is a key step in the production of semi-branched-chain C11-13 alcohol ether sulfate, and controlling oxidation conditions is crucial to the quality and performance of the final product.

Separation and refining: After completing the oxidation reaction, the resulting product is separated and refined. The sulfate was separated from the reaction solution by centrifugation, precipitation, or extraction, and then washed and dried to obtain high-purity half-branched chain C11-13 alcohol ether sulfate.

Quality testing and control: In the production process, it is necessary to carry out quality testing and control of the reaction products at each step to ensure that the quality and performance of the final product meet the requirements. Testing items include chemical structure, purity, stability, surface activity, etc.

Packaging and storage: After quality inspection and control, half-branched chain C11-13 alcohol ether sulfate can be packaged and stored. Packaging materials should have good sealing and barrier properties to ensure the quality and stability of the product during storage and use. The storage environment should be kept dry, cool, well well-ventilated, and avoid direct sunlight and high temperatures.
