“…Бензол и циклогексан применяются уже несколько сотен лет, тогда как тиофен и тиофан взяты на вооружение химиками с середины прошлого века. Их термодинамические и реакционные свойства входят в различные химические базы данных [1], и на современном этапе изучение свойств этих веществ носит уточняющий характер [2][3][4][5]. Самым последним из серосодержащих гетероциклов на основе циклогексана был открыт 1,2,3,4-тетратиан, его идентичность была подтверждена уже в этом тысячелетии в работе [6].…”

Изучено распределение электронной плотности 14 циклических соединений и одного нециклического. Проведен анализ зарядов и объемов групп, найдены группы доноры и акцепторы электронной плотности. Рассмотрено изменение электронной плотности серосодержащих групп под влиянием окружения. The electron density distribution of 14 cyclic compounds and one non-cyclic compound was studied. The group charges and group volumes were analyzed, and the electron density donor and acceptor groups were found. Changes in the electronic density of sulfur-containing groups under the influence of the environment are considered.

Recent advances in coating techniques and improved polymers employed as gas chromatographic stationary phases have resulted in commercializing low phase ratio capillary column technology with respectable chromatographic efficiency and inertness. Highly volatile compounds that are critical in challenging industrial applications such as alkanes, alkenes, arsine, phosphine, oxygenated, and sulfur compounds have been successfully analyzed with respectable chromatographic performance and resolution using a low phase ratio column such as a 60 m × 0.32 mm id × 8 µm polydimethylsiloxane (PDMS) with a β value of 10. An R value of 5.6 was achieved for the separation of hydrogen sulfide and carbonyl sulfide without the use of cryogenic chromatography. In addition to improved retention for highly volatile organic compounds, a low phase ratio column can be employed effectively to enhance chromatographic inertness for reactive analytes. The augmentation of a 3D-printed two stage microreactor for use with flame ionization detection enabled carbon compound independent response, thereby lower cost-of-ownership and improved lab safety.
