Title: Innovations by Inventor Thomas Schieb
Introduction
Thomas Schieb, an accomplished inventor based in Rosrath, Germany, has significantly contributed to the field of chemical engineering with a total of ten patents to his name. His work primarily focuses on the efficient production of dinitrotoluene, a compound widely used in the synthesis of explosives and chemicals.
Latest Patents
One of Thomas Schieb's latest innovations involves an adiabatic process for producing dinitrotoluene (DNT). This method entails the adiabatic nitration of toluene using nitric acid at temperatures ranging from approximately 60 to 200 degrees Celsius, with a specific molar ratio of toluene to nitric acid between 1:1.5 and 1:3.0. The process is designed to concentrate the reaction mixture to a water content of up to 30% by weight. Notably, it ensures the effective recovery of DNT from the reaction mixture, either prior to or following this concentration. Additionally, any DNT present in the vapor during concentration is captured as a liquid through the introduction of a solvent, allowing for the recycling of both the solvent and the DNT produced.
Another relevant invention from Schieb pertains to a process for the production of dinitrotoluene, where toluene is nitrated with nitrating acid under controlled adiabatic conditions. This sophisticated procedure ensures some mononitrotoluene remains in the reaction mix, enhancing the overall efficiency. The subsequent treatment of the reaction mixture involves removing at least 5% of the water content before it is separated into an acid phase and an organic phase, enabling the efficient recovery of dinitrotoluene from the organic phase.
