Latest Patents
One of Bockmann's latest patents is a process for the production of nitrobenzene. This innovative method involves subjecting benzene to nitration with a mixture of nitric acid and sulfuric acid. The process includes separating off the nitrobenzene formed, concentrating the sulfuric acid by evaporation, and returning the concentrated sulfuric acid to the benzene nitration stage. The improvement lies in concentrating sulfuric acid to a concentration of 75% to 92% by evaporation in vacuo at temperatures ranging from 130°C to 195°C. This method drastically reduces the energy required per kilogram of water evaporated compared to traditional processes, without sacrificing efficiency or capacity.
Another significant patent by Bockmann is for the preparation of terephthaloyl and isophthaloyl dichlorides. This improved process involves the chlorination of dimethyl terephthalate and isophthalate with chlorine gas at temperatures between 100°C and 250°C. The process optionally includes the presence of light and/or catalysts that promote side-chain chlorination of aromatic compounds. Notably, 20% to 200% by weight of terephthaloyl and/or isophthaloyl dichloride is added to the dimethyl terephthalate and/or isophthalate for the chlorination.
