An alkyl group can be added to a benzene molecule by an electrophile aromatic substitution reaction called the Friedel‐Crafts alkylation reaction. One example is the addition of a methyl group to a benzene ring.1. The table above shows us that as the size of the alkyl substituent already present in the ring increases, attack at the ortho position becomes more difficult, and the percentage of ortho isomers in the mixture of products decreases. LAS is the main ingredient in household detergents.8 billion by 2025, after growing at a CAGR of 4. Several routes have been used for the production of linear alkylbenzene.

Flash point above 100℃; Alkyl benzene sulfonic acid is easily sulfonated with linear Alkyl Benzene (LAB) and fuming sulfuric acid or SO3. 3. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. In this instance, the observed ortho/para ratio is almost 2:1, as we might expect. The benzylic hydrogens of alkyl substituents on a benzene ring are activated toward free radical attack, as noted earlier. Stop the spill at source if it is safe to do so.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.
