What is the production process of Lauric Acid, Ester With 2-Hydroxyethanesulfonic Acid Sodium Salt?
Lauric Acid, Ester With 2 - Hydroxyethanesulfonic Acid Sodium Salt, that is, the ester of lauric acid and sodium 2 - hydroxy ethanesulfonate, which is more commonly known as lauryl ether sulfosuccinate monoester disodium salt, is a common surfactant. The preparation method is as follows:
Initially, lauryl alcohol, maleic anhydride, sodium bisulfite and other raw materials need to be prepared, all of which need to be combined with the corresponding purity specifications.
The first step is the esterification reaction, with lauryl alcohol and maleic anhydride as materials. According to a specific molar ratio, the molar ratio of lauryl alcohol to maleic anhydride is usually about 1:1.05 - 1:1.2. Add an appropriate amount of catalyst, such as p-toluenesulfonic acid, in an amount of about 0.5% - 2% of the total mass of the reactants. Heat up to 120-140 ° C, stir the reaction under nitrogen protection for 3-5 hours. In this process, anhydride and alcohol are esterified to produce lauryl alcohol monoester maleate. Real-time acid value measurement monitors the reaction process. When the acid value drops to a specific range, it indicates that the esterification reaction is nearly complete.
The second time is a sulfonation reaction. The obtained lauryl alcohol monoester was cooled to 80-90 ° C. Slowly add sodium bisulfite aqueous solution according to a certain molar ratio. The molar ratio of lauryl alcohol monoester to sodium bisulfite is about 1:1.1 - 1:1.3. In this step, the mono-ester is sulfonated with sodium bisulfite to obtain lauryl ether sulfosuccinate mono-ester. The sulfonation rate is determined by iodometry to control the degree of reaction.
The end is neutralized to form a salt. Sulfonation, until the reaction solution is cooled to 60-70 ° C, neutralize in sodium hydroxide solution. The concentration of sodium hydroxide is about 20% - 30%, and neutralize to the pH value of the reaction solution 7-9, to obtain the finished product of Lauric Acid, Ester With 2 - Hydroxyethanesulfonic Acid Sodium Salt. Subsequent processes are often decolorized and filtered to improve product purity and appearance quality.
The entire preparation process requires strict control of reaction temperature, time, material ratio and other conditions to ensure that product quality and performance meet standards.
