What is Dodecyl Sulfate De Sodium?

Dodecyl Sulfate De Salt is an anionic surfactant, a normal agent of sulfate surfactants, called SDS, similarly called AS, K12, Salt Coco Sulfate, Salt Lauryl Sulfate, lathering representative, sold on the marketplace The property is typically white to somewhat yellow crystalline powder, safe, somewhat soluble in alcohol, insoluble in chloroform along with ether, soluble in water, and also has excellent compatibility with anions along with non-ions, as well as also has excellent emulsifying, lathering, Lathering, permeating, sanitizing and dispersing houses, rich in foam, fast biodegradation, nevertheless water solubility is substandard to that of fatty alcohol polyoxyethylene ether sulfate (AES for brief). It is not aware antacids along with hard water, however its safety and security is substandard to that of basic sulfonates under acidic troubles, close to AES, and also lasting home heating has to not exceed 95 ° C. It is higher than AES as well as less than Dodecyl Sulfate De Sodium (LAS for quick). Toxicity LD50 is 1300mg/kg. Today, there is no proof that this item is carcinogenic. High doses might definitely irritate the skin. Nevertheless, when made use of as a frothing representative as a whole washroom products, the concentration is restricted, and also it remains in line with the criteria of different nations worldwide, so you do not require to tension. Dodecyl Sulfate De Salt is the cornerstone in dish soap. Typically used in DNA extraction procedures to different healthy and balanced proteins from DNA after denaturation. Typically misread as sodium dodecyl sulfonate. As a lathering rep, it is extensively used in tooth paste, soap, body laundry, hair shampoo, cleaning up powder, along with cosmetics. Dodecyl Sulfate De Salt is uncovered in 95% of personal skin treatment and residence cleansing products.

Dodecyl Sulfate De Sodium Uses

  1. Dodecyl Sulfate De Salt has excellent detergency, emulsifying and also lathering power, can be used as detergent and fabric auxiliary, additionally utilized as anionic surfactant, tooth paste lathering agent, mine fire snuffing out representative, foaming representative of fire extinguisher, Solution polymerization emulsifier, emulsifying as well as spreading agent for medicine, cosmetic products such as hair shampoo, woollen detergent, detergent for great silk and woollen materials. Flotation representative for steel beneficiation.
  2. Dodecyl Sulfate De Salt is a handling aid for food industry defined in GB 2760-96. Lathering representative; emulsifier; anionic surfactant. For cakes, beverages, healthy protein, fresh fruit, fruit juice drinks, edible oil, and so on.
  3. Dodecyl Sulfate De Sodium is used in 1. Surfactant, purification, frothing, wetting agent, and so on 2. Relatively low-level ion-pair reagent, when the requirements are low, it is less expensive than heptane, salt pentane sulfonate 3, As resources, adjustment of products 4, capillary electrophoresis evaluation, ingredients, it is normally utilized in molar options 5, and also various other analysis methods will certainly also be utilized, such as flow column evaluation.

Dodecyl Sulfate De Sodium Application and Precautions

Dodecyl Sulfate De Sodium is a white or yellowish slightly sticky substance frequently utilized in the cleaning agent and also fabric markets. It is an anionic surfactant. It is easily soluble in water, has excellent compatibility with anions and non-ions, as well as has excellent emulsifying, frothing, passing through, sanitizing and also dispersing residential properties. It is commonly utilized in toothpaste, shampoo, hair shampoo, hair shampoo, cleaning powder, liquid Washing, cosmetics and pharmaceutical, paper, building materials, chemicals as well as various other sectors.

Dodecyl Sulfate De Sodium is a crucial fatty alcohol sulfate complex salt type anionic surfactant. Sodium fatty alcohol sulfate is a white to light yellow strong, quickly soluble in water. Rich foam, great detergency and also emulsification, great biodegradability, tough water resistance, appropriate for reduced temperature level cleaning, simple rinsing, and much less bothersome to the skin. Dodecyl Sulfate De Salt is a regular agent of sulfate type anionic surfactants. Melting point 180-185 ℃, 185 ℃ disintegration. It is conveniently soluble in water, has an unique smell, and also is non-toxic. Its foam performance, detergency, emulsifying power are much better. Can be biodegraded. It is resistant to antacids and tough water, yet it is prone to hydrolysis in strong acid option, as well as its security is even worse than that of sulfonate. It can be utilized as mine fire extinguishing agent, toothpaste foaming representative, cleaning agent, emulsifier for polymer synthesis, fabric accessories and also other commercial auxiliaries.

Carcinogen: annoying to mucous membrane layers and top respiratory system tract, annoying to eyes and also skin. Can cause allergies in the respiratory system. Surge Danger: This product is flammable, irritating as well as animating. In case of open fire and high warm, it is flammable. Broken down by high warm to launch poisonous gases. Dangerous combustion items: carbon monoxide, co2, sulfides, sodium oxide. Call Dealing With Skin Get in touch with: Remove polluted clothing and wash with lots of running water. Eye Get In Touch With: Raise the eyelids and also flush with running water or regular saline. look for medical attention. Inhalation: Eliminate from site to fresh air. If breathing is hard, provide oxygen. look for clinical interest. Ingestion: Drink adequate cozy water to induce vomiting. seek clinical interest. Fire battling techniques: Firefighters need to wear gas masks and also full-body firefighting matches to put out the fire in the upwind direction. Snuffing out media: water mist, foam, completely dry powder, carbon dioxide, sand. Emergency treatment of leak: Separate the polluted location as well as restrict accessibility. Cut off the resource of ignition. It is suggested that emergency employees wear dust masks (complete face masks) as well as protective clothing. Stay clear of dust, very carefully scoop, put in a bag as well as transfer to a safe place. If there is a huge amount of leak, cover it with plastic bed linen or canvas. Collect and reuse or deliver to garbage disposal site for disposal.

Preparation of Dodecyl Sulfate De Sodium

Synthesis principle: It is prepared by neutralizing lauryl alcohol with chlorosulfonic acid or sulfamic acid. Main instruments and medicines: electric stirrer, electric heating mantle, mortar, tray balance, hydrogen chloride absorption device, Roche foam meter, four Flask (250mL), dropping funnel (60mL), beaker (50mL, 250mL, 500mL), thermometer (0-100°C, 0-150°C), simple measure (10mL, 100mL). Cinnamyl alcohol, sodium hydroxide, urea, chlorosulfonic acid, sulfamic acid, sodium hydroxide solution (mass fraction 5%, 30%), chloroform, methanol, sulfuric acid silica gel G, extensive PH test paper.

Add 62g of lauryl alcohol to a 250mL four-necked flask equipped with a hydrogen chloride absorption device, a thermometer, an electric stirrer and a dropping funnel, control the temperature to 25°C, and slowly add 24 mL of chlorosulfonic acid dropwise within 30 min with a dropping funnel under full stirring , the temperature should not exceed 30 ℃ when dripping, pay attention to foaming, do not make the material overflow. After adding chlorosulfonic acid, react at (30+2)° C. for 2 hours, and absorb the hydrogen chloride gas generated in the reaction with 5% sodium hydroxide solution by mass. After the sulfation, the sulfate was slowly poured into a 250 mL beaker containing 100 g of ice and water (ice: water = 2: 1), while stirring well, and the outside was cooled with an ice-water bath. Finally, all the reactants in the four-necked flask were washed out with a small amount of water. After the dilution is uniform, 30% sodium hydroxide solution is added dropwise under stirring to neutralize to pH 7-8.5. Samples were taken for thin layer chromatography. A 2g sample was taken in a 50mL beaker to measure the solids content and foam properties. 2. Take a small amount of sample with a glass for thin layer chromatography and put it into a test tube, prepare a solution with a mass fraction of about 2%, and use a capillary to spot the sample. Adsorbent: silica gel G Developing agent: chloroform: formazan (mass fraction 5% 0.05mol*L-1)=80:20 Expanding height: 12cm This product is a white or light yellow solid, soluble in water, and a translucent solution.
