Description
Dodecylbenzene is a colorless liquid with a weak oily odor, which floats on water and is characterized by its chemical properties as a colorless, odorless liquid that is insoluble in water but soluble in organic solvents.
Uses
Used in Detergent Industry:
Dodecylbenzene is used as a precursor to sodium dodecylbenzenesulfonate, a surfactant that is a key ingredient in household laundry detergents such as Tide. It serves as a widely used cleaner due to its effective cleaning properties.
Used in Textile Industry:
In the textile industry, Dodecylbenzene is utilized as a dyeing assistant, enhancing the dyeing process and improving the quality of the final product.
Used in Electroplating and Leather Industry:
Dodecylbenzene functions as a degrease agent in electroplating and leather industries, effectively removing grease and oils from surfaces.
Used in Paper Industry:
It is employed as a de-inking agent in the paper industry, helping to remove ink from recycled paper and contributing to the production of cleaner, recycled materials.
Used in Rubber and Plastic Industry:
Dodecylbenzene is used in the rubber and plastic industry as a break emulsion agent, which aids in the separation of oil and water in emulsions, improving the manufacturing process.
Used in Oil Industry:
In the oil industry, Dodecylbenzene serves as an artesian well foaming agent, enhancing the extraction process of oil from artesian wells.
Used in Synthetic Detergent Production:
Dodecylbenzene is used as a raw material for the production of synthetic laundry detergents and biodegradable detergents, contributing to the development of more environmentally friendly cleaning products.
Used in Microemulsion Preparation:
1-Phenyldodecane, a derivative of Dodecylbenzene, acts as a pseudo-stationary phase (PSP) marker in the preparation of microemulsions, which are important in various industrial and pharmaceutical applications.
Preparation
n-Dodecylbenzene was prepared by lauroyl chloridation, Friedel-Crafts acylation and Huang Minglong deoxidization, followed by purification with vacuum distillation and recrystallization procedures.
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
1-Phenyldodecane was degraded to phenylacetic acid by an oil-degrading bacterium.
Check Digit Verification of cas no
The CAS Registry Mumber 123-01-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123-01:
(5*1)+(4*2)+(3*3)+(2*0)+(1*1)=23
23 % 10 = 3
So 123-01-3 is a valid CAS Registry Number.

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.

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.
