An example of a linear alkylbenzene sulfonate (LAS) Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. [2] In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. [9]
Synthetic sulfonates are the most widely used detergents, as industrial oil, emulsifiers, demulsifiers, rust inhibitors, dispersants, surfactants for enhanced oil recovery, ore-floatation agents, and wetting agents, among others. LABs such as alkylbenzene, dialkylbenzene, and alkyltoluene are most commonly used to prepare sulfonate detergents. [4]
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
Today one of the most commonly used anionic surfactants, linear alkylbenzene sulfates (LAS), are produced from petroleum products. However, surfactants are increasingly produced in whole or in part from renewable biomass , like sugar, fatty alcohol from vegetable oils, by-products of biofuel production, or other biogenic material.
Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1.Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12-C 15, C 12-C 13 and C 10-C 13, for detergent use. [1]
A man was killed by police after they say he fatally shot his wife and their 2-year-old daughter, and also injured their two other children, in Louisiana.
The resulting sulfonic acid is then neutralized with base to give sodium alkylbenzenesulfonate, which is subsequently blended with other components to produce cleaning products. [1] Dodecylbenzene (and its isomers) are precursors to linear alkylbenzene sulfonate detergents. [2]
It ranks as the second-most destructive fire in Southern California history – behind only the nearby Eaton Fire. Containment efforts on both wildfires continue. Tim Jones, an ATF deputy ...
