Patent ID: 8722918

Claim:
A process for producing C 1 -C 4 alkyl nitrite, comprising: loading a porous filler layer into a reactor; passing nitrogen oxide, oxygen and an alkanol chosen from C 1 -C 4 alkanol through the porous filler layer in a counter current, parallel current or cross current manner, wherein the reactor has a reaction temperature ranges from 0 to 150° C., a reaction pressure ranges from −0.09 to 1.5 MPa, a molar ratio of C 1 -C 4 alkanol to nitrogen oxide ranges from 1-100:1, and a molar ratio of nitrogen oxide to oxygen ranges from 4-50:1, wherein said nitrogen oxide is NO, or a mixed gas containing NO and one or more selected from N 2 O 3 and NO 2 , wherein the reactor is a rotating high-gravity reactor comprising a rotor.
