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 ]
It is dangerous to try to dispose of benzene by washing it down a sink, since it is toxic, will cause environmental damage and presents a fire risk. It is probable that trying to dispose of benzene in this way will also break local environmental rules. Instead, retain in a safe place in the laboratory (well away from any source of ignition)
Aromatization is a chemical reaction in which an aromatic system is formed from a single nonaromatic precursor. Typically aromatization is achieved by dehydrogenation of existing cyclic compounds, illustrated by the conversion of cyclohexane into benzene.
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 ...
In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:
The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene, such as halogenation, cyanation, trifluoromethylation, and hydroxylation. The reaction was discovered in 1884 by Swiss chemist Traugott Sandmeyer , when he attempted to synthesize phenylacetylene from benzenediazonium chloride and copper(I ...
The benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids using a base.This reaction receives its name from the reaction of benzil with potassium hydroxide to form benzilic acid.
Preparation. 1,3,5-Triethylbenzene can be prepared by a Friedel-Crafts alkylation of benzene with ethyl bromide in presence of aluminium chloride. [4] Properties
