Yuan, Qian published the artcileTriptycene-based dicationic guanidinium ionic liquid: A novel stationary phase of high selectivity towards a wide range of positional and structural isomers, Product Details of C5H12O, the main research area is triptycene derivative dicationic guanidinium ionic liquid stationary GC isomer; Aromatic and aliphatic isomers; Dicationic guanidinium ionic liquid, gas chromatography; Essential oil; Separation performance; Triptycene-based stationary phase.

This work presents a new triptycene-based dicationic guanidinium ionic liquid (TPG) as the stationary phase for gas chromatog. (GC). To knowledge, this is the 1st example of employing a dicationic guanidinium ionic liquid (GIL) for chromatog. analyses. As a result, the TPG column exhibited moderate polarity and column efficiency of 3840 plates/m and 3120 plates/m measured by naphthalene and 1-octanol at 120°, resp. Particularly, the TPG column exhibited distinctly advantageous performance for the challenging Grob test mixture and the isomer mixture of phenols and anilines over the monocationic GIL and its counterpart with dicationic immidazolium units (TP-2IL). Also, it showed higher selectivity towards the isomers of alkanes, alcs., diethylbenzenes, bromotoluenes, bromonitrobenzenes than the com. DB-35MS column. Also, the TPG column achieved improved thermal stability over the GIL column and excellent repeatability with the relative standard deviation values of 0.01-0.05% for run-to-run, 0.11-0.24% for day-to-day and 2.4-4.1% for column-to-column. Its application to GC-MS anal. of the essential oil of Mentha haplocalyx proved its good potential for anal. of complex samples.

Ponomarev, A. V. published the artcileEffect of Boiling on the Mechanism of Formation and Decay of Hydroxyalkyl Radicals, Recommanded Product: 3-Pentanol, the main research area is propanol radial reaction mechanism.

The effect of the boiling state on the reaction mechanism of 11 free radicals formed upon irradiation of 1-propanol with 8 MeV accelerated electrons is considered. Compared to radiolysis at room temperature, radiolysis at boiling results in an increase in 1-propanol degradation yield from (10.1 ± 0.9) to (13.3 ± 0.9) mol./100 eV. Boiling shows the largest effect on the radiolytic cleavage of the C(1)-H and C(2)-H bonds and almost doubles the yield of hydroxyalkyl radicals. In particular, the boiling effect is due to the suppression of the cage effect, a decrease in the relative role of intermol. relaxation, and an increase in the processes of radicals exchange and combination.

Ponomarev, A. V. published the artcileAcceleration of radical exchange and combination in 1-propanol under irradiation and boiling, Application In Synthesis of 584-02-1, the main research area is propanol radical bond cleavage radiolysis reaction mechanism.

The yield of radiolytic degradation of 1-propanol is 13.3 ± 0.9 mols./100 eV in a boiling state and 10.1 ± 0.9 mols./100 eV in ambient conditions when irradiated with 8 MeV accelerated electrons. Boiling increases the yields of diols by 1.7 times and of heavy monohydric alcs. arising via the radical combination by 1.3 times. At the same time, due to boiling, the total yield of methanol and ethanol decreases 2.1 times, and the yield of aldehydes and hydrocarbons – 1.3 times. Boiling accelerates the dissociation of some radicals and radical-cations, facilitates the radical exchange and favors a combination of hydroxypropyl radicals. However, both in liquid and boiling alc., the total yield of splitting of C-H bonds remains approx. twice as high as C-C bonds.
