Linear Alkyl Benzene Sulfonic Acid (LABSA), the highly preferred industrial surfactant, was in high demand in the second quarter of 2022.2. Page ID. Although the reactions are exothermic overall because of the strengths of all the new carbon-hydrogen bonds being made, there is a high Introduction. Corresponding Author. In alkylbenzenes, the carbon atom which is attached to the aromatic ring is particularly reactive. Step 2: loss of H2O gives the nitronium ion, a very strong electrophile. The silver nitrate test is sensitive enough to detect fairly small concentrations of halide ions. However, if we study the ortho/para ratio found in the nitration of a number of other arenes, we see that this is not always the case. This gave rise to an indeterminate mixture of Abstract Linear alkylbenzene (LAB) is a cost-effective and biodegradable intermediate in the production of detergents and surfactants. Alkyl benzene sulfonates have two types depending on their chain structures: branched and linear chain. There are two equivalent ways of sulfonating benzene: Heat benzene under reflux with concentrated sulfuric acid for several hours. According to Perego and Ingallina, the process for making LABs comprises the alkylation of benzene with linear internal olefins, and most of the installed capacity is probably based on HF catalysts (298). LAB is consumed chiefly globally and is used to produce laundry The basic reaction involves the nucleophilic attack of the carbanionic carbon in the organometallic reagent with the electrophilic carbon in the carbonyl to form alcohols.2. Prices for LABSA have been on the rise since February when production was halted for the winter Olympics and Chinese New Year. Below is a list of commonly seen benzene-derived compounds.
