Usage

Chemical Properties

Colorless, odorless liquid. Insoluble in water, soluble in organic solvents.

Uses

n-Dodecylbenzene, is a precursor to sodium dodecylbenzenesulfonate, a surfactant that is a key ingredient of household laundry detergents, such as Tide. It is a widely used cleaner, dyeing assistant in textile industrial, degrease agent in electroplate, leather, de- inking agent in papering, rubber and plastic, break emulsion agent in oil industry, artesian well foaming agent in oil well.

Application

Dodecylbenzene is used as a raw material for synthetic laundry detergents and production of biodegradable detergents.1-Phenyldodecane acts as a pseudo-stationary phase (PSP) marker in the preparation of microemulsion.

Preparation

n-Dodecylbenzene was prepared by lauroyl chloridation, Friedel-Crafts acylation and Huang Minglong deoxidization, followed by purification with vacuum distillation and recrystallization procedures.

General Description

Dodecylbenzene is a colorless liquid with a weak oily odor. Floats on water. (USCG, 1999)

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DODECYLBENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

Health Hazard

Liquid causes mild irritation of eyes and may cause allergenic responses on repeated contact with skin. Ingestion causes nausea.

Fire Hazard

DODECYLBENZENE is combustible.

Biochem/physiol Actions

DODECYLBENZENE (cas 123-01-3) transformations: Dealkylation and disproportionation over immobilized ionic liquid catalysts09/07/2019

AlCl3-based ionic liquids (ILs) supported on silica and MCM-41 have been used for disproportionation and dealkylation of dodecylbenzene (DDB) at low reaction temperature. AlCl3-based ionic liquids supported on MCM-41 were highly active for the conversion of DDB. Up to 55 mol% conversion and sele...detailed

Polypyrrole doped with DODECYLBENZENE (cas 123-01-3) sulfonate as a protective coating for copper09/06/2019

Polypyrrole doped with dodecylbenzene sulfonate (DBS) was formed at copper, PPy–DBS, and at a thin coating of polypyrrole doped with tartrate to form a bilayer of PPy–Tar/PPy–DBS at copper. The two polymer coatings showed good protective properties. Breakdown potentials of 0.85 V and 0.93 V v...detailed

Roles of supports on reducibility and activities of Cu3P catalysts for deoxygenation of oleic acid: In situ XRD and XAS studies

This work demonstrates for the first time that SiO2 and ultra-stable zeolite Y (USY) supports play significant roles in the reducibility of Cu2P2O7 to form Cu3P, which consequently affects the selectivity of oleic acid deoxygenation. The formation of supported Cu3P nanoparticles during hydrogen reduction of Cu2P2O7 was carefully investigated by in situ X-ray diffraction (in situ XRD), and in situ X-ray absorption spectroscopy (in situ XAS). The results indicate that the transformation of Cu2P2O7 to Cu3P occurs through several steps. In the first step, all supported Cu2P2O7 precursors are reduced to metallic Cu. Then, copper particles on SiO2 support react with phosphorus compounds and directly transform to Cu3P. On the other hand, copper particles on USY support partially transform to CuP2 and Cu(OH)2 before all converting to Cu3P. Despite multi-step transformations, Cu2P2O7/USY exhibits the lowest onset reduction temperature and provides Cu3P with a small particle size. The deoxygenation of oleic acid over Cu3P supported catalysts reaches nearly 100 % conversion. Both catalysts favor cyclization and aromatization to form cyclic and aromatic compounds. Cu3P/SiO2 achieves higher dodecylbenzene yield (46 %) than Cu3P/USY (33 %). A proposed mechanism consists of hydrogenation of oleic acid and deoxygenation, then followed by cracking, cyclization, aromatization, and alkyl rearrangement.

Borane evolution and its application to organic synthesis using the phase-vanishing method

Although borane is a useful reagent, it is difficult to handle. In this study, borane was generated in situ from NaBH4 or nBu4NBH4 with several oxidants using a phase-vanishing (PV) method. The borane generated was directly reacted with alkenes, affording the desired alcohols in good yields after oxidation with H2O2 under basic conditions. The selective reduction of carboxylic acids with the evolved borane was examined. The organoboranes generated by the PV method successfully underwent Suzuki–Miyaura coupling. Using this PV system, reactions with borane can be carried out easily and safely in a common test tube.
