titleOfInvention | Process for preparing caprolactam by beckmann rearrangement |
abstract | The invention relates to a process for preparing caprolactam by admixture of cyclohexanone oxime to a reaction mixture comprising caprolactam and sulfuric acid using a mixing device, said mixing device comprising (i) a tube through which the reaction mixture can flow, and (ii) channels disposed around the tube, said channels opening into the tube, said process comprising: passing the reaction mixture through the tube, and feeding the cyclohexanone oxime into the reaction mixture through one or more of said channels, wherein Re>5000, Re being the Reynolds number as defined by rho.V.D/eta, wherein rho=density (in kg/m<SUP>3</SUP>) of the reaction mixture that is fed to the tube V=velocity of the reaction mixture, V being defined as W/A, wherein W is the flow rate (in m<SUP>3</SUP>/s) of the reaction mixture that is fed into the tube and A is the cross section area of the tube (in m<SUP>2</SUP>) at the level where said channels open into the tube D=diameter of the tube at the level where said channels open into the tube (in m) eta=viscosity of the reaction mixture that is fed into the tube (in Pa.s). |
