FIELD: chemistry. SUBSTANCE: invention relates to use of tetrahydrobenzoxazines in which substitute R 1 denotes a hydrocarbyl residue having 1-3000 carbon atoms, and substitutes R 2 , R 3 , R 4 and R 5 independently denote hydrogen atoms, hydroxyl groups or hydrocarbyl residues, having 1-3000 carbon atoms, respectively, and in which substitutes R 3 and R 4 or R 4 and R 5 with a partial structure -O-CH 2 -NR 7 -CH 2 -, bonded to the benzene ring, can also form a second tetrahydrooxazine ring, where R 7 denotes hydrocarbyl residues having 1-3000 carbon atoms, provided that at least one of substitutes R 1 , R 2 , R3, R 4 , R 5 or R 7 are polyisobutenyl, having 3000 carbon atoms and the rest of the substitutes from the group R 1 , R 2 , R 3 , R 4 , R 5 or R 7 , if they denote hydrocarbyl residues, have 1-20 carbon atoms, respectively, as anti-oxidants for stabilising mineral oil and fuel products against the effect of light, oxygen and heat. The invention also describes jet fuel and jet fuel additive concentrate containing tetrahydrobenzoxazine of formula (I). EFFECT: preparation of stabilisers having improved stabilisation of nonliving organic material, particularly jet fuel against the effect of light, oxygen and heat. 9 cl, 14 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 412 234 (13) C2 (51) МПК C10L 1/22 (2006.01) C07D 265/16 (2006.01) C07D 498/04 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2008106666/04, 18.07.2006 (24) Дата начала отсчета срока действия патента: 18.07.2006 (73) Патентообладатель(и): БАСФ СЕ (DE) R U Приоритет(ы): (30) Конвенционный приоритет: 26.07.2005 DE 102005035527.7 (72) Автор(ы): ЛАНГЕ Арно (DE), МАХ Хельмут (DE), РАТ Ханс Петер (DE), ПОССЕЛЬТ Дитмар (DE) (43) Дата публикации заявки: 10.09.2009 Бюл. № 25 2 4 1 2 2 3 4 (45) Опубликовано: 20.02.2011 Бюл. № 5 2 4 1 2 2 3 4 (85) Дата начала рассмотрения заявки PCT на национальной фазе: 26.02.2008 C 2 C ...
