ALKYL IMIDAZOLINES AND THEIR ETHOXYLATED DERIVATIVES AS ANTIOXIDANTS FOR HYDROCARBON PRODUCTS
نویسندگان
چکیده مقاله:
Alkyl imidazolines have been reportedly used in a wide range of industrial formulations with different applications. Ethoxylated alkyl imidazolines with appropriate ethoxylation degrees can be used as antioxidants and retarders in the formation of peroxides resulting from oxidation in hydrocarbon media. In this work, ethoxylated imidazolines were shown to be more effective in hydrocarbon media in comparison with reference antioxidants. According to the experimental results, ethoxylated alkyl imidazolines (12 moles EO), as an antioxidant, were twice as efficient as zinc dialkyldithiophosphoric acid (ZDDP).

متن کاملMycosporine-Like Amino Acids and Their Derivatives as Natural Antioxidants.
Mycosporine-like amino acids (MAAs) are water-soluble molecules that absorb UV-A and UV-B radiation and disperse the energy as heat. MAAs show great diversity in their molecular structures, which exhibit a range of molecular weights spanning 188 to 1050 Daltons. MAAs are utilized in a wide variety of organisms including prokaryotes and eukaryotic micro-organisms that inhabit aquatic, terrestria...
متن کاملRing-alkyl connecting group effect on mesogenic properties of p-carborane derivatives and their hydrocarbon analogues
The effect of the phenyl-alkyl connecting group on mesogenic properties of several series of isostructural compounds containing p-carborane (A and B), bicyclo[2.2.2]octane (C), and benzene (D) was investigated using thermal and optical methods. Results demonstrated that mesophase stability in the series containing A-D follows the order (Alk)CH₂CH₂- < (Alk)OOC- < (Alk)CH₂O- < (Alk)COO-. Surprisi...
متن کاملAlkyl Ethoxylated and Alkylphenol Ethoxylated Nonionic Surfactants: Interaction with Bioactive Compounds and Biological Effects
Nonionic surfactants are amphipathic molecules consisting of a hydrophobic (alkylated phenol derivatives, fatty acids, longchain linear alcohols, etc.) and a hydrophilic part (generally ethylene oxide chains of various length). Although not as important commercially, tertiary amine and various sugar surfactants are also nonionic surfactants. Due to their favorable physicochemical properties, no...
متن کاملHydrocarbon products and their derivatives in fish of the Pechora River, North-Eastern European Russia.
Analysis of one of the major surface oil spill consequences, which took place in 1994 on the territory of the Pechora River (Russia) catchment area, was carried out. Data on hydrocarbon products and their derivatives concentrations in muscle and liver tissues of several fish species living in the Pechora's Delta and the river tributaries were obtained. Comparative analysis of OCCs, PCBs and PAH...
متن کاملTropane alkaloids as medicinally useful natural products and their synthetic derivatives as new drugs.
Secondary metabolites of Solanaceae plants, sharing tropane skeleton as a common structural feature, are sharply divided into two classes: tropine and ecgonine derivatives. The first group, represented by well known alkaloids: atropine and scopolamine, which are considered to be model anticholinergic drugs, continues to provide inspiration in the search for more selective muscarinic receptor an...
