Inhibition of the hydrogen + oxygen reaction by ethylene. Part 1.—Kinetic results

Abstract

The inhibiting action of C2H4 on the first and second limits of the H2+02 reaction has been studied over a wide range of mixture composition and vessel diameter in KC1-coated vessels. The results are similar to those observed with C2H6, C3H8 and C4H10, except that the inhibition efficiency of c2H4 decreases with pressure. The efficiency of C2H4 is linearly dependent on 0 2 mole fraction, and virtually independent of Hz mole fraction and vessel diameter. Analysis of reaction products

A literature survey of the chemistry of flame inhibition

“…Inhibition of the H 2-O 2 chain by ethylene [29,30], apparently does not involve OH radicals or [H2], but is linearly dependent on the [0 2], This view is reasonable, since OH is a product, not a reactant, in the H 2 -O 2 chain reaction. At least part of the oxidation of CO depends on the presence of OH (reaction 3).…”

Колебательная Неравновесность В Реакции Водорода С Кислородом (Обзор)

“…Ингибирующее действие добавок многоатомных газов на реакцию водорода с кислородом было обнаружено в середине прошлого века и наблюдалось экспериментально при использовании ряда углеводородов (от пентана до октана), а также низших спиртов, метана и пропана [102]. В последующие десятилетия, ввиду чрезвычайной практической важности проблемы ингибирования газофазного горения, взрыва и детонации, к этому списку были добавлены этан [103,104], формальдегид [105], этилен [106] (vi1) HO 2 (100) + inh k=1 (0) → HO 2 (000) + inh k=1 (1), (vi2) HO 2 (010) + inh k=2 (0) → HO 2 (000) + inh k=2 (1), (vi3) HO 2 (001) + inh k=3 (0) → HO 2 (000) + inh k=3 (1),…”

Steroidomimetic Aminomethyl Spiroacetals as Novel Inhibitors of the Enzyme Δ8,7‐Sterol Isomerase in Cholesterol Biosynthesis

“…Ergosterol is the main sterol in the cytoplasmatic membranes of fungi and trypanosomes, and disruption of ergosterol biosynthesis is the main strategy for treatment of fungal and trypanosomal infections . Further, inhibitors of ergosterol biosynthesis in plant‐pathogenic fungi play a central role in crop protection . The azoles are the most widely used antifungal drugs, but due to emerging resistance against these drugs ( e.g ., fluconazole), there is urgent need for developing novel antifungals .…”
