Предложен новый подход к определению дибензотиофенов в дизельных топливах методом ВЭЖХ-МС/МС с ионизацией электрораспылением. В основе разработанной методики лежит предварительная дериватизация целевых соединений результате их взаимодействия алифатическими спиртами присутствии трифторметансульфоновой кислоты, приводящих образованию производных со связанным зарядом. Такие производные претерпевают предсказуемые процессы фрагментации, связанные элиминированием из образующегося катиона алкена,...
The separation of used engine oil (UEO) with an ultrafiltration (UF) membrane made commercial copolymer poly(acrylonitrile-co-methyl acrylate) (P(AN-co-MA)) has been investigated. P(AN-co-MA) sample was characterized by using FTIR spectroscopy, 13C NMR and XRD. UF a mean pore size 23 nm fabricated non-solvent-induced phase method—the casting solution 13 wt.% in dimethylsulfoxide (DMSO) precipitated the water bath. Before experiment, diluted toluene, resulting UEO toluene (100 g/L) filtered...
Monolithic capillary columns based on pentaerythritol triacrylate and tetraacrylate were synthesized using different compositions of polymerization mixtures conditions. The impact porogen type porogen/monomer ratio the porosity monoliths was investigated. Porogen appears to be main factor influencing separating properties monolithic sorbent. Using optimal conditions (porogen type, ratio, reaction temperature, time etc.) with a porous structure optimized for polymer separations can obtained....
Polycyclic aromatic sulfur-containing compounds are widely distributed in oil, especially its low-volatile and heavy fractions (resins, asphaltenes), this dictates the need for their determination when reliable methods sulfur removing, cleaning processing oil developed. In these cases, "soft" ionization mass spectrometry methods, based on electrospray (ESI) matrix-assisted laser desorption/ionization (MALDI), particularly effective. However, have low polarity cannot be readily ionized by...
Abstract Monolithic layers prepared by the copolymerization of ethylene dimethacrylate and glycidyl methacrylate deposited onto surface glass silicon plates were investigated as thin‐layer chromatography separation media in hyphenated with matrix‐assisted laser desorption/ionization mass spectrometry (MALDI‐MS) analysis. Varying composition polymerization mixture conditions different porosities MALDI‐MS compatibility synthesized. Compatibility was tested using polyethylene glycol it...
