Mono-tert-butyl ethers of ethylene glycol (ETBE) and 2,3-butanediol (BTBE) were prepared by direct acid-catalyzed alkylation of the corresponding diols with tert-butanol. The substances obtained were characterized by main physical properties (density, viscosity, boiling point, crystallization point, specific heat of combustion) and were studied as additives to automobile gasolines. The effect of ether additives on the main physicochemical properties of gasolines (fractional composition, saturated vapor pressure, concentration of actual resins, knock resistance), including ethanol-containing gasolines, was studied. The mean research/motor blending octane numbers for ETBE and BTBE were 130/103 and 115/97, respectively. Inclusion of ETBE/BTBE into the formulations of ethanol-containing gasolines allowed the cloud point to be considerably reduced without unambiguous synergistic effect on the knock resistance.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты второй части исследования вицинальных ( трет -бутокси)алканолов в качестве добавок к автомобильным бензинам. Простые моно -трет- бутиловые эфиры этиленгликоля (ТБЭЭ) и 2,3-бутандиола (ТБЭБ) были получены прямым кислотно-каталитическим алкилированием соответствующих диолов трет -бутанолом. Полученные вещества были охарактеризованы по основным физическим свойствам (плотность, вязкость, температура кипения, температура кристаллизации, удельная теплота сгорания) и исследованы в качестве добавок к автомобильным бензинам. Описано влияние добавок эфиров на основные физико-химические свойства бензина (фракционный состав, давление насыщенных паров, концентрация фактических смол, детонационная стойкость), в том числе и для случая этанолсодержащих бензинов. Показано, что средние октановые числа смешения по исследовательскому/моторному методам для ТБЭЭ и ТБЭБ составили 130/103 и 115/97 единиц соответственно. Вовлечение ТБЭЭ/ТБЭБ в состав этанолсодержащих бензинов позволяло добиться значительного снижения температуры помутнения при отсутствии однозначного синергетического эффекта во влиянии на детонационную стойкость.</p></trans-abstract><kwd-group xml:lang="en"><kwd>glycols</kwd><kwd>2,3-butanediol</kwd><kwd>ethers</kwd><kwd>alcohols</kwd><kwd>oxygenates</kwd><kwd>gasoline</kwd><kwd>octane number</kwd><kwd>octane boosters</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гликоли</kwd><kwd>2,3-бутандиол</kwd><kwd>простые эфиры</kwd><kwd>спирты</kwd><kwd>оксигенаты</kwd><kwd>бензин</kwd><kwd>октановое число</kwd><kwd>октаноповышающие добавки</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Самойлов В.О., Столоногова Т.И., Рамазанов Д.Н., Тюрина Е.В., Лаврентьев В.А., Порукова Ю.И., Чернышева Е.А., Капустин В.М. трет-Бутиловые эфиры возобновляемых диолов как оксигенатные добавки к автомобильным бензинам.
