LABSA Linear Alkylbenzene Sulfonic Acid


What Is LABSA linear alkylbenzene sulfonic acid

  • Other name: DBSA, DDBSA, Sulfonic acid, Dodecyl benzene sulfonic acid
  • Molecular formula: C18H30O3S
  • CAS No.: 85536-14-7
  • HS Code: 34021100
  • Appearance: Brown viscous liquid

LABSA, with the full chemical name of linear alkylbenzene sulfonic acid, is a kind of organic compounds with brown viscous liquid in appearance. LABSA chemical is an organic weak acid and is corrosive to a certain extent. It is soluble in water, generates heat when diluted with water, and is insoluble in common organic solvents. As a synthetic chemical surfactant, it has the functions of emulsifying, dispersing and decontamination. So LABSA is mainly used as detergent raw material.

What Is Linear Alkylbenzene Sulfonic Acid Used For

LABSA is mainly used in the detergent industry. It is one of the most important and cheapest surfactants in laundry powder and liquid detergent.

Used together with other surfactants as wetting agent and small amount of emulsifier for the lathering of soaps.

Used in the manufacture of sodium, calcium and ammonium salts of anionic surfactant alkyl benzene sulfonic acid.

Used as emulsifier for organochlorine and organophosphorus pesticides.

Used as a washing and mercerizing agent in the textile industry.

Because it is stable in acidic solution and has good washing performance, LABSA chemical is often used in the preparation of acidic solution detergents, such as, toilet cleaners.

Due to its high active substance content, low salt content and miscibility with water, LABSA can be used in emulsion polymerization and in the production of coupling agents, emulsifiers, agricultural herbicides, household and industrial cleaners.

More About Sodium Lauryl Ether Sulfate

The preparation method of alkylbenzene sulfonate includes alkylation, sulfonation, neutralization and other processes. Alkylation is a process in which hydrogen fluoride or aluminum chloride is used as a catalyst to react benzene with olefins or chlorinated alkanes with about 12 carbon atoms to produce alkylbenzene.

The industrial preparation method of linear alkyl benzene sulfonate is prepared by sulfonation of linear alkyl benzene. In the most common preparation method, benzene is alkylated from long-chain monoolefins using hydrogen fluoride as a catalyst. Purified dodecylbenzene is sulfonated with sulfur trioxide to get the sulfonic acid. Then neutralize sulfonic acid with sodium hydroxide.

Sulfonation is a process in which alkylbenzene is reacted with concentrated sulfuric acid, oleum or sulfur trioxide to form alkylbenzenesulfonic acid. Neutralization is generally the process of neutralizing the alkylbenzene sulfonic acid with sodium oxide.

Dodecyl benzene sulfonic acid and its sodium salt are anionic surfactants with the most production technology and the largest annual output.

LABSA chemical has the characteristics of strong degreasing ability, high foam, low coat and good penetration.

There is no branched chain in the alkyl group. So it has good biochemical degradation performance.

Linear alkylbenzene sulfonic acid has a significant detergency effect on particulate soils, protein soils and oily soils.

It is particularly effective for cleaning particulate soils on natural fibers.

The detergency is enhanced with the increase of washing temperature.

More effective on protein soils than non-ionic surfactants.

In order to obtain better comprehensive washing effect,LABSA is often used in combination with non-ionic surfactants.

Solubility. The smaller the number of carbon atoms in the alkyl substituent, the shorter the alkyl chain, the worse the hydrophobicity. And it is easier to dissolve in water at room temperature. Conversely, the more carbon atoms, the longer the alkyl chain, the stronger the hydrophobicity, and the harder to dissolve.

Surface tension. With the increase of the number of alkyl carbon atoms, the surface tension value showed a downward trend. The surface tension referred to here is the surface tension of the solution when the surfactant concentration is higher than the CMC.

Wetting force. With the increase of the number of alkyl carbon atoms, the wetting power of surfactants decreased.

Foaming power. As the number of alkyl carbon atoms increases, the foaming power of surfactants increases.

Cleaning power. As the number of carbon atoms increases, the cleaning power of surfactants increases gradually.

Most anionic surfactants, including LABSA chemical, are nontoxic in nature. However, prolonged exposure to these surfactants may irritate and damage the skin by disrupting the lipid membranes that protect the skin and other cells.

Biodegradability is determined by the hydrophobic hydrocarbon group of the surfactant. LABSA chemical is biodegradable and environmentally friendly.
