What is sodium alkyl benzene sulfonate used for?
What is sodium alkyl benzene sulfonate used for?
Sodium linear alkylbenzene sulfonate (LAS) is an anionic surfactant. It is widely used as consumer products contained in laundry detergents and kitchen detergents. For the industrial use, LAS is mainly used as emulsifiers, emulsifier for paints & coatings, and others.
What is linear alkyl benzene sulfonate?
Linear alkylbenzene sulfonate (LAS), the world’s largest-volume synthetic surfactant, which includes the various salts of sulfonated alkylbenzenes, is widely used in household detergents as well as in numerous industrial applications. The LABSA market is driven by the markets for LAS, primarily household detergents.
What is linear alkyl sulfonate?
Linear alkyl sulfonate (LAS) is an anionic surfactant widely used in detergents and cleaners, both in industrial and household applications. The linear alkyl chain of the LAS makes the molecule more biodegradable than branched alkyl benzene sulfonates. LAS is found in waste water.
What are alkyl sulfonates used for?
Alkyl sulfonates are esters of alkane sulfonic acids with the general formula R-SO2-O-R’. They act as alkylating agents, some of them are used as alkylating antineoplastic agents in the treatment of cancer, e.g. Busulfan.
What is LABs acid?
DESCRIpTION. Laurylbenzene Sulfonic Acid is a surfactant used in chemical formulations and detergent manufacturing industries. FEATURES. Viscous amber brown coloured liquid.
What is LABs in detergent?
Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C6H5CnH2n+1. The CnH2n+1 chain is unbranched. They are mainly produced as intermediate in the production of surfactants, for use in detergent.
Where is linear alkyl benzene used?
Linear Alkyl Benzene (LAB) is used as surfactant in dilute solutions for their cleaning properties. Linear alkyl benzene is derived from petroleum and is the major detergent being used today, because of its low cost. LAB is the basic raw material for production of most widely used detergent.
How is linear alkyl benzene made?
Linear alkylbenzenes have been produced commercially via the following routes: 1) Dehydrogenation of n-paraffins to internal olefins followed by alkylation with benzene using a hydrofluoric acid (HF) catalyst; 2) Dehydrogenation of n-paraffins to internal olefins followed by alkylation with benzene using a fixed-bed of …
Is linear alkylbenzene sulfonate toxic?
Linear alkylbenzene sulfonate (LAS) is a common organic pollutant in freshwater environments. Studies have shown that the toxicity of LAS to aquatic plants is directly related to the LAS concentration and depends on the plant species.
How do you make linear alkylbenzene sulfonates?
Linear alkylbenzene sulfonates. Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst.
What is sodium alkylbenzene sulfonate used for?
Sodium AlkylBenzene Sulfonate As an anionic surfactant Sodium AlkylBenzene Sulfonate is mainly used to prepare various types of liquid, powder, granular detergents. Get TDS & MSDS
What is the general structure of sodium dodecylbenzenesulfonates?
The general structure of Sodium dodecylbenzenesulfonates, prominent examples of alkylbenzene sulphonates Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group.
How do you convert dodecylbenzenes to sulfonic acid?
The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid. The sulfonic acid is subsequently neutralized with sodium hydroxide.
