Sodium dodecyl benzene sulfonate is white to light yellow flakes, odorless, small particles or powder. Dissolves in water to form a translucent solution. Melting point >300 °C, boiling point 660.62ºC[at 101 325 Pa], density 1.02 g/cm3, vapor pressure 0Pa at 25ºC, acidity coefficient (pKa)0.7[at 20 ºC, water solubility 800mg/L at 25ºC.
Sodium dodecyl benzene sulfonate, anionic surfactant, a very typical sulfonate, with decontamination, emulsification and other effects, can be used as a detergent and other applications, but the resistance to hard water is slightly weak, and chelating agent matching use effect is better, the application field is very wide, typical use is used in washing powder.
Sodium alkyl benzene sulfonate is a yellow oily body, which can form hexagonal or rhombic strong flake crystals after purification, with mild toxicity, and has been recognized as a safe chemical raw material by international safety organizations. Sodium alkyl benzene sulfonate can be used in fruit and tableware cleaning, the largest amount used in detergent, due to the use of large-scale automated production, low price, sodium alkyl benzene sulfonate used in detergent has branch chain structure (ABS) and straight chain structure (LAS) two, the branch chain structure is small biodegradability, will cause pollution to the environment, and the straight chain structure is easy to biodegrade, The biodegradability can be greater than 90%, and the degree of environmental pollution is small. Sodium dodecyl benzene sulfonate is neutral, sensitive to water hardness, not easy to oxidize, foaming power is strong, cleaning power is high, easy to mix with various auxiliaries, low cost, mature synthesis process, wide range of applications, is a very excellent anionic surfactant. Sodium dodecyl benzene sulfonate has significant decontamination effect on particle dirt, protein dirt and oily dirt, especially on natural fiber particle dirt, decontamination power increases with the washing temperature, the effect on protein dirt is higher than that of non-ionic surfactants, and foam is abundant. However, sodium dodecyl benzene sulfonate has two disadvantages, one is poor resistance to hard water, decontamination performance can be reduced with the hardness of water, so the detergent with its main active agent must be used with an appropriate amount of chelating agent. Second, the degreasing force is strong, hand washing has a certain irritation to the skin, the feel of the clothes is poor after washing, it is appropriate to use cationic surfactants as softening agents. In recent years, in order to obtain better comprehensive washing effect, sodium dodecyl benzene sulfonate is often used in combination with non-ionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). The main use of sodium dodecyl benzene sulfonate is to prepare various types of liquid, powder, granular detergents, cleaning agents and cleaning agents.
Used as anionic surfactant, it is the synthetic surfactant with the largest amount of household detergent
Used as silk printing, penetration and degumming refining aid
Used as textile auxiliaries
Processing AIDS for the food industry. Anionic surfactant. Excellent foaming power and detergency.
1.SDBS can be used as the main ingredient in advanced detergents and cleaners, it can bleach, and remove stains and oil and anti-static.
2.SDBS can be used as an efficient emulsifier for the polymerization of pressure sensitive adhesives.
3.SDBS can be used as an antistatic additive for textile oil with cleaning function.
4.SDBS is a highly efficient polyester substrate and film based antistatic agent, especially suitable for polyester based films and film strips.
5.SDBS can be used as antistatic agent of polyolefin, polyester and other polymer materials.
6.SDBS can be used as an anti-hygroscopic and anti-caking additive for powdery chemical products, such as urea, etc. Adding 0.3-0.5% can increase crystalline particles, moisture-proof, remove static electricity, and prevent caking. SDBS is a kind of efficient additive which can improve the quality of organic and inorganic chemical products which are easy to absorb moisture and caking.
7.SDBS can be used as a good degreaser for high-quality leather
