What Is Linear Alkyl Benzene Sulfonic Acid

Linear Alkyl Benzene Sulfonic Acid is an organic compound with the molecular formula C18H30SO3. It is light yellow to brown viscous liquid, soluble in water, and generates heat when diluted with water. Slightly soluble in benzene and xylene, easily soluble in methanol, ethanol, propanol, ether and other organic solvents. It has the functions of emulsification, dispersion and decontamination. is a surfactant.

What is the use of linear alkylbenzene sulfonic acid?

Linear alkylbenzene sulfonic acid is mainly used to manufacture sodium salt, calcium salt and ammonium salt of anionic surfactant alkylbenzene sulfonic acid, and also used as emulsifier for organochlorine and organophosphorus pesticides. It can be used as a curing catalyst for amino baking varnishes, used to prepare various liquid and solid detergents, and also used in various cosmetic formulations. Because it is stable in acidic solution and has good washing performance, it is often used in the preparation of acidic solution detergents such as toilet cleaners

Anionic surfactant. Due to its low production cost and good performance, it is widely used and is the largest synthetic surfactant used in household detergents. It also produces some inorganic salts such as magnesium and calcium and organic amine salts such as triethanolamine. There is Linear Alkyl Benzene Sulfonic Acid in washing powder, and in addition to washing powder, various household cleaning products are also used。

Properties of linear alkylbenzene sulfonic acid

The first and greatest characteristic of linear alkylbenzene sulfonic acid is its toxicity. In fact, it is a dangerous product, because it itself is toxic, and a very small amount of product is very toxic, so more care should be taken during transportation. At the same time, paraalkylbenzene sulfonic acid is also flammable, and it is also a combustible product, which produces toxic sulfur oxide fumes when burned. It is precisely because of its characteristics of dangerous goods that its storage and transportation characteristics are that the warehouse is ventilated, low-temperature and dry; and it is guaranteed to be stored separately from food raw materials

If it really burns, it needs to be extinguished in time. There are many fire extinguishing agents available, such as dry powder, foam, sand, carbon dioxide, and mist water.

Upstream raw materials and transportation of linear alkylbenzene sulfonic acid

It is precisely because of the current strong market of linear alkylbenzene sulfonic acid that it drives the prosperity of its upstream market. First of all, from its upstream. The main raw material of linear alkylbenzene sulfonic acid is linear alkylbenzene, referred to as LAB. Linear alkylbenzene (linear alkylbenzene) is a petroleum term published in 1994 and is also an aromatic hydrocarbon compound. Alkylbenzene is a colorless or light yellow transparent liquid without suspended matter. Its chemical properties are stable. The flash point is above 100°C; it is easy to sulfonate with oleum or SO3 to generate alkylbenzenesulfonic acid. It is the most important raw material for domestic household detergent products. In terms of packaging, it is mostly packed in tank trucks or iron drums, and should be stored in a cool, ventilated, and dry place, and isolated from fire. Waterproof and oil-proof paint or stickers should be used on the barreled container to mark: product name, trademark, grade, production batch number and standard number; when the product is loaded, there should be a gap according to the temperature change, and the container should be tightly closed after loading And seal it. During transportation, there should be coverings to avoid direct sunlight, rain and moisture, and throwing and collision are strictly prohibited during loading and unloading. When storing, the lid should face up, and a rainproof cover should be added for outdoor storage to prevent exposure to the sun and rain.
