Alkylbenzene - Wikipedia
It is the raw material in the production of synthetic sulfonate detergents, which are found in a variety of household products such as soap, shampoo, toothpaste, laundry detergent, etc. Linear alkylbenzenes (LAB) and branched alkylbenzenes (BAB) are families of alkylbenzene used to prepare synthetic sulfonates. However, LABs are more ...

2022年8月10日 · Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. [2] The term "linear" refers to the starting alkenes rather than the final product.
Alkylbenzene sulfonate - Wikipedia
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 ]
Linear Alkylbenzenes: An Overview of the Commercial HF and …
2023年3月10日 · Linear alkylbenzene (LAB) is the precursor to the biodegradable detergent surfactant linear alkylbenzene sulfonate (LAS). This chapter will review the two predominant commercial alkylation routes for LAB production: homogenous acid alkylation using hydrofluoric (HF) acid and solid acid alkylation.
Linear alkylbenzene - Almeida - 1994 - Journal of the American …
1994年7月1日 · Linear alkylbenzene (LAB) was introduced in the mid-1960s as a raw material for cleaning products. Since then, continuing and explosive research on its biodegradation and on its environmental and human toxicity has been performed.
LINEAR ALKYLBENZENE SULFONATES
This unspecific ingredient, LINEAR ALKYLBENZENE SULFONATES, can be found in 140 products.
Linear alkylbenzene sulphonate (LAS) is an anionic surfactant. It was introduced in 1964 as the readily biodegradable replacement for highly branched alkylbenzene sulphonates (ABS).
Linear Alkylbenzene Prices | Current and Forecast - Intratec.us
Linear Alkylbenzene (a.k.a. LAB) refers to a group of organic compounds with a benzene 'head' followed by a tail of linear chain with 10 to 16 carbons. LABs are obtained from n-paraffins and benzene. n-Paraffins are a product of jet kerosene hydrotreating, which are dehydrogenated to linear olefins, that are reacted with benzene in the presence ...
Alkylbenzene Linear Process by UOP LLC
2018年6月2日 · The UOP/CEPSA process uses a solid, heterogeneous catalyst to produce linear alkylbenzene (LAB) by alkylating benzene with linear olefins made by the UOP Pacol, DeFine and PEP processes. Linear paraffins are fed to a Pacol reactor (1) to dehydrogenate the feed into corresponding linear olefins.
Linear Alkylbenzene - TEAMChem
Linear Alkylbenzene (LAB), which is made up of two groups, Alkyl and Benzene, is also known as detergent alkyl. It is an intermediate substance in the petrochemical industry that is obtained from the alkylation of Benzene from paraffin in raw materials.
