WebAromatic Substitution Reactions Part II. 4. Electrophilic Substitution of Disubstituted Benzene Rings. When a benzene ring has two substituent groups, each exerts an influence on subsequent substitution reactions. The activation or deactivation of the ring can be predicted more or less by the sum of the individual effects of these substituents. WebThe reactivity to PDH (C 3 H 8, 7 ml/min; H 2, 7 ml/min; N 2, 11 ml/min) was studied over different Pt-3dTM/SBA-15 catalysts. For comparison, the reactivity of Pt/SBA-15 was also tested. First, Fig. 2A displays the PDH reactivity of unleached Pt-3dTM/SBA-15 and Pt/SBA-15 catalysts.

WebHydrogen, H 2, does react with oxygen, O 2, unless ignited with a flame or a spark (and the mixture is the right ratio). The reaction is a fire or explosion, depending on the conditions, with a characteristic reddish flame. 2 H 2 (g) + O 2 (g) 2 H 2 O (g) Nitrogen can be brought to react with hydrogen. This is called the Haber process [5]: WebHydrogen has a higher diffusivity than helium, thus its optimum linear velocity is higher and can be used at a higher flow rate without adversely affecting efficiency. Specifically, under isothermal analysis conditions, the typical linear velocity for hydrogen is 40 cm/sec, which is twice the optimum linear velocity of helium at 20 cm/sec.
