Uses

Used in Personal Care Industry:
Pyridinium Butylsulfonate is used as a conditioning agent for [application reason] to alleviate dryness and facilitate moisture retention in hair and skin care products such as shampoos, conditioners, and lotions. Its effectiveness in improving the texture and manageability of hair, as well as providing hydration to the skin, makes it a valuable component in these formulations.
However, it is important to note that there is limited information available on the safety profile and potential toxicity of Pyridinium Butylsulfonate. Therefore, caution is recommended with prolonged and extensive exposure to this chemical in personal care products. Further research and testing are necessary to fully understand its impact on human health and the environment.

Application of pyridinium ionic liquid as a recyclable catalyst for acid-catalyzed transesterification of jatropha oil

A series of pyridinium ionic liquids were synthesized and characterized. Acid-catalyzed transesterifications of Jatropha oil were carried out with these ionic liquids under mild reaction conditions. [BSPy]CF3SO3 showed the best catal

By combining phosphotungstic acid (PW) and SO3H- functioned zwitterion, heteropoly anion-based Br?nsted acidic ionic liquids (HPA-ILs) were successfully obtained. Scanning electron microscopy and energy dispersive X-ray spectroscopy were provid

SO3H-functionalized organic-inorganic ionic liquids based on polyoxometalates characterization and their application in C-C coupling reaction

Different ionic liquids (ILs) with SO3H as functional group were achieved by combining SO3H-functionalized organic cations and polyoxometalates (POM). The obtained salts were characterized and their catalytic activities investigated

Recyclable supported Br?nsted acidic ionic liquid catalysts with non-aromatic cations for the oligomerization of isobutene under mild conditions

Br?nsted acidic ionic liquids with different type of cations (pyridinium, morpholinium, pyrrolidinium, imidazolium), N-sulfoalkyl chain length and different anions (triflate, hydrogensulfate and tetrafluoroborate) were prepared and immobilised on silica by adsorption. The ionic liquids were characterised by NMR and IR. Surface properties and Br?nsted/Lewis acidity of the supported catalysts were also determined. Their catalytic activity and recyclability were compared in the oligomerisation of isobutene to obtain products that can be used as jet fuel blending components after hydrogenation. The results proved that imidazolium ionic liquids can be replaced by less toxic non-aromatic versions without any loss in their activity and stability. By the introduction of shorter sulfoalkyl chain into the cation, excellent results could be obtained even under milder conditions (lower temperature and shorter reaction time). Catalytic activity was shown to correlate to the Br?nsted acidity of the catalyst.

Zwitterionic Hydrobromic Acid Carriers for the Synthesis of 2-Bromopropionic Acid from Lactide

A convenient and highly efficient way of synthesizing 2-bromopropionic acid (2-BrPA) from lactide is presented. The procedure uses ionic liquids obtained from the addition of HBr to ammonium-based zwitterions as the solvent and bromination agent. The buffered HBr acidity, high polarity, and charge stabilizing character of the ionic liquid (IL) enable the synthesis of 2-BrPA with excellent selectivity. The best results are obtained with an imidazolium-based IL, that is, 1-(4-butanesulfonic acid)-3-methylimidazolium bromide ([MIMBS]Br). The HBr loading and water content of the IL are crucial parameters for the bromination reaction. The formed 2-BrPA product can be selectively isolated by extraction from the IL, and the unconverted substrate remains in the [MIMBS]Br IL for the next run. Successful recycling of the IL over four cycles is demonstrated.

A two-phase system for the clean and high yield synthesis of furylmethane derivatives over -SO3H functionalized ionic liquids

A new and effective unique two-phase reaction system is investigated for the high yield production of tri(furyl)methane from furfural and furan. This strategy includes the use of an acidic aqueous phase (water + -SO3H functionalized IL) and furan phase, which significantly suppresses polymer formation, thereby increasing the yield of tri(furyl)methane. Furan serves as a reactant as well as an extraction solvent for the recovery of the condensation products. For comparison, different -SO3H functionalized ionic liquids are prepared and their performances evaluated for the condensation of furan and furfural. The ionic liquids with alkyl chain linkers are found to be more effective and acidic than those with imidazolium linked N-sulfonic acids. In addition, an increase in carbon chain length between imidazole/tri-ethylamine/pyridine and -SO3H, increases the catalytic activity of the respective ionic liquids. Among the several prepared ionic liquids, the strongly acidic imidazolium based butylsulfonic acid 6 shows the best activity with a maximum condensation product yield of 84%. This strategy offers a significantly high yield of the condensation products of furan and furfural compared to the traditional mineral acid route. The activity and stability of the -SO3H functionalized 6 is confirmed from seven successful recycles, in which there is no reduction in its activity. Finally, this new strategy is successfully extended for the condensation of furan derivatives (e.g. furan and 2-methylfuran) with several different aldehydes, ketones and alcohols.
