Patent ID: 8476469

Claim:
A process of producing a C 1 -C 4 alkyl nitrite comprising: a) firstly feeding nitrogen oxide and oxygen into Reactor I, contacting with an aluminosilicate catalyst, and reacting to produce an effluent I containing NO 2 and unreacted NO; b) feeding the effluent I and a C 1 -C 4 alkanol into Reactor II, and reacting to produce an effluent II containing the C 1 -C 4 alkyl nitrite; and c) separating the effluent II containing the C 1 -C 4 alkyl nitrite to obtain the C 1 -C 4 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 N 2 O 3 and NO 2 , wherein the molar number of NO is greater than that of NO 2 , if any; and the molar ratio of NO in nitrogen oxide to oxygen is 4-25:1.
