Abstract: FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing aromatic amines, namely to preparing unsubstituted or N-methyl- substituted aromatic amines that are used in production of dyes, drugs, antioxidants and antidetonating additives to fuel and so on. Method for preparing aromatic amines involves the reduction reaction of corresponding nitro-compounds with methanol in vapor phase at elevated temperature in the presence of industrial copper-containing catalyst, for example, type "Virgon", or "S-40", or "NTK-10-7F" modified with nickel or palladium, or platinum and taken in the amount 0.3-10 wt.-%. Usually process is carried out at temperature 200-260 C, under atmosphere pressure and feeding rate of the parent liquid mixture of methanol with aromatic nitro-compound from 0.5 to 2.5 t -1  and maintaining the ratio methanol/aromatic nitro- - compound in the parent mixture from 1:1 to 5:1. Proposed method ensures to enhance the total yield of aromatic amines up to 99.5%, output by product up to 0.4-1.3 g/g x h and safety of process due to exclusion of hydrogen and carrying out the process under atmosphere pressure. Method allows depending on ratio of used reagents to alternate ratios of synthesized N-methyl-substituted and unsubstituted aromatic amines. EFFECT: improved preparing method. 4 cl, 1 tbl

Abstract: Изобретение относится к противопожарной технике и может быть использовано для тушения пожаров при помощи (газоаэрозольной, газопорошковой, газопылевой, газожидкостной и т.п.) смеси в открытых и закрытых резервуарах с легковоспламеняющими жидкостями (ПК). Сущность изобретения заключается в том, что тушение пожара в резервуарах с ЛВЖ и ГЖ осуществляется путем подачи в зону горения жидкости снизу вверх огнетушащей газодисперсной смеси (ГДС), образующейся путем подачи под давлением не менее 2 МПа газообразного и/или сжиженного газового флегматизатора и/или газообразного, и/или сжиженного гомогенного ингибитора горения, и/или углеводородофобного поверхностно-активного вещества (ПАВ) в емкость с порошкообразным или жидким гетерогенным ингибитором горения, имеющей клапан, обеспечивающий выпуск ГДС при достижении давления в емкости не ниже 0.42 КПа через перфорированный распылитель или через несколько распылителей, обеспечивающих распыление ГДС на 180° с расходом не менее 1 кг/с в направлении, параллельном поверхности горящей жидкости и в верхнюю полусферу над поверхностью жидкости с интенсивностью, обеспечивающей создание концентрации ГДС в центре объема пламени над зеркалом горящей поверхности, не менее 0.09кг/м 3 , при соотношении масс между газовой и дисперсной фазами огнетушащей смеси от 0.2:1 до 15:1. При этом в качестве газовой составляющей ГДС используют инертный газ (CO 2 , N 2 , А 2  или их смесь) и/или озононеразрушающий галогеноводород, а в качестве гетерогенного ингибитора горения используют огнетушащий порошковый состав на основе карбонатов и/или хлоридов или фосфатов щелочного, и/или щелочноземельного металла, и/или аммония или туманообразующий раствор ортофосфорной кислоты или термореагирующий огнетушащий порошковый состав (ТРОПС). При этом подачу ГДС ведут одновременно из плавающих на поверхности ЛВЖ или ГЖ генераторов этой смеси, расположенных по периметру резервуара и в его центре, причем результирующий вектор горизонтального распыла периферийных генераторов направлен к центру, а центральных - к периферии. Для предупреждения загорания ЛВЖ и ГЖ в резервуаре на поверхность жидкости наносят слой ТРОПСа с плотностью, меньшей плотности жидкости, и/или лиофобного по отношению к ней в количестве, обеспечивающем сплошное покрытие поверхности жидкости в резервуаре. Изобретение обеспечивает повышение безопасности тушения пожара при снижении удельного расхода огнетушащего вещества. 4 з.п.ф-лы, 2 ил., 1 табл.
