Uses

Used in Cleaning Products Industry:
p-Decylbenzenesulphonic acid is used as a surfactant and anionic detergent for its ability to enhance the cleaning power of various products. It is particularly effective in dishwashing detergents, laundry detergents, and industrial cleaners due to its strong wetting and emulsifying properties, which help to remove dirt and grease efficiently.
Used in Agricultural Industry:
In the agricultural sector, p-decylbenzenesulphonic acid is utilized in the production of pesticides and herbicides. Its surfactant properties aid in the even distribution and absorption of these agrochemicals, improving their effectiveness in controlling pests and unwanted plant growth.
Used in Metalworking Fluids Industry:
p-Decylbenzenesulphonic acid serves as a corrosion inhibitor in metalworking fluids. Its presence helps to prevent the degradation of metal surfaces during manufacturing processes, thereby extending the life of machinery and tools.
Used in Oilfield Chemicals Industry:
As a coupling agent in the formulation of oilfield chemicals, p-decylbenzenesulphonic acid is instrumental in improving the performance of various products used in the extraction and processing of oil. Its surfactant nature facilitates better interaction between different components of oilfield chemicals, enhancing their overall effectiveness.

Smectic liquid crystals from supramolecular guanidinium alkylbenzenesulfonates

A homologous series of guanidinium alkylbenzenesulfonates from ethyl to tetradecyl were synthesized and characterised. Their thermotropic polymorphism was investigated by polarizing optical microscopy, differential scanning calorimetry, and dilatometry. The structure of the smectic liquid crystal phases obtained at high temperature with the compounds from octyl to tetradecyl was analysed by X-ray diffraction. The supramolecular assembling of the ionic species inside the smectic layers was investigated by infrared spectroscopy.

PROPRIETES PHYSICI-CHIMIQUES DE N-ALKYL P-BENZENE SULFONATES ALCALINS: TEMPERATURE DE KRAFFT ET CONCENTRATION CRITIQUE MICELLAIRE

The Krafft points (Tk) and the critical micellar concentrations (c.m.c.) on the alkali salts of n-alkyl-p-benzene sulfonates have been measured by solubility and conductivity experiments.For the sodium compounds, we observe a linear relationship between log10cmc and n the number of carbon atoms in the alkyl chain of the surfactant, a linear relationship between the Tk of the homologous surfactants studied and n.The substitution of sodium counter-ion by another alkali, decreases the Krafft point which seems to be correlated to the hydratation of the counter-ion.These data permit us to know the Tk and c.m.c. of homologous series of various amphiphiles.By treating the formation of micelles as analogous to phase separation, the determination of the variation of c.m.c. with temperature has been studied, these results have been converted into, enthalpy and free energy of micellization and these have been compared with corresponding values obtained from literature data.
