摘要: A process of producing C1-C4 alkyl nitrite, comprising the following steps: a) firstly feeding nitrogen oxide and oxygen into Reactor I, contacting with an aluminosilicate catalyst, and reacting to produce an effluent I containing NO2 and unreacted NO; b) feeding the effluent I and C1-C4 alkanol into Reactor II, and reacting to produce an effluent II containing C1-C4 alkyl nitrite; and c) separating the effluent II containing C1-C4 alkyl nitrite to obtain C1-C4 alkyl nitrite; wherein reactor I is a fixed bed reactor, and Reactor II is a rotating high-gravity reactor; said nitrogen oxide in step a) is NO, or a mixed gas containing NO and one or more of N2O3 and NO2, wherein the molar number of NO is greater than that of NO2, if any; and the molar ratio of NO in nitrogen oxide to oxygen is 4-25:1.

摘要: Provided are processes for producing an oxalate by coupling of CO in the presence of a nitrite, wherein two or more reaction zones in series are used, and at least a portion of the oxalate as reaction product is separated between the reaction zones, and/or the nitrite is fed stagewise. The processes described herein can effectively enhance the selectivity to the oxalate and the single-pass conversion of the feedstock.

摘要: Embodiments monitor application performance metrics representing the performance of a software application executed by one or more host computing devices. Based on the application of rules to the application performance metrics, an elasticity action, such as a power-on action, a power-off action, a deploy action, and/or a destroy action, is determined. The elasticity action is transmitted to one or more target hosts, which perform the elasticity action. The target host may be selected based on host performance metrics. Further, a load balancing service may accommodate the addition of a new software application instance to a cluster and/or the removal of an existing software application instance from the cluster.
