Alkyl benzene sulfonate คือ
WebBenzenesulfonic acid has the characteristic reactions of a strong aromatic sulfonic acid. Acid hydrolysis at 175 C splits it into benzene and sulfuric acid. Additional sulfonation with fuming sulfuric acid gives 1,3-benzenedisulfonic acid, which reacts further to 1,3,5-benzenetrisulfonic acid, and also diphenyl sulfone disulfonic acid. Web3.2.2.3 Linear Alkyl Benzene Production Linear alkyl benzene (LAB) is a raw material for making the detergent intermediate LAB sulfonate (298) . 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) .

WebFigure 1 shows the reaction to produce a sulfonate. Sulfur trioxide (SO3) reacts with an organic molecule – in this case an alkyl benzene – to form a sulfur-carbon bond. One of the characteristics of this process is that the resultant alkyl benzene sulfonic acid is a stable molecule. Figure 1. Sulfonation SO3 + (CH2) 11 - CH3 CH 3- (CH2) 11 Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways.
