Abstract
A multi-step process for producing DNT employing a mononitration step in a single liquid phase at an elevated temperature using a carefully controlled amount of water, followed by a phase separation step prior to dinitration of the MNT present in the resulting organic phase. This process results in a DNT product with a desired isomer ratio of 2,4-DNT to 2,6-DNT and provide relatively fast nitration rates with less by-products.
