Production method of linear alkylbenzene (sulfonic acid)
Hydrotreated kerosene is a typical feedstock for high-purity linear paraffins (N-paraffins), which are subsequently converted to linear olefins by dehydrogenation. CnH2n+2 → CnH2n + H2 Alternatively, ethylene can be oligomerized (partially polymerized) to produce linear alkenes. The resulting linear monoolefins react with benzene in the presence of a catalyst to produce linear alkylbenzene (labsa) . Hydrogen fluoride (HF) and aluminum chloride (AlCl3) are the two main catalysts for the alkylation of benzene with linear monoolefins. The production process using hydrogen fluoride is economically more affordable and is usually used more often. However, the risk of hydrogen fluoride being released as a toxic substance into the environment has become a concern, especially after the amendment of the Clean Air Act. In 1995, a solid catalyst system (DETAL process) became available. This method eliminates the process of catalyst neutralization and HF disposal. As a result, most linear alkylbenzene plants built since then use…
Untold information’s about Linear alkyl benzene
Family of cleaning agents In previous articles we talk about detergents and surfactants major using of labsa is as foaming detergent which is for cleaning. Like shampoo soap and other cleaning agents Linear alkyl benzene and untold information’s There are several applications for Linear alkyl in different industries but there are two untold information’s which nobody might not hear about it. As all know sulfonic acid is an organic acid that exists as brown liquid and is used in many industries .This acid is used as raw material or accompanying material in many organic reactions .The molar mass of this organic acid is equal to 158.17 g/mol and its density is equal to 1.32 g/m3. This material boils at a temperature of about 190 centigrade. Now lets see what are those two applications which is new to hear. Used in the production of a variety of drugs From LABS…
