| titleOfInvention | Bromination production process of methyl isopropyl ketone |
| abstract | The invention belongs to the technical field of a bromination production process of methyl isopropyl ketone, and particularly relates to a bromination production process of methyl isopropyl ketone, which comprises the following steps: adding methyl isopropyl ketone and methanol into a 500L reaction kettle, mixing and stirring uniformly, cooling to-5 ℃, pumping bromine, stirring until the temperature suddenly rises, the red color fades or is light red, sampling, and controlling the raw materials to be qualified, wherein the raw materials are controlled to be less than 5%; cooling to-5 deg.C, pumping into 1000L kettle, quenching, transferring the reaction solution from 500L kettle to 1000L kettle, stirring overnight, adding 550kg water, separating lower organic layer, extracting water phase with DCM for three times, mixing organic phases, 88L 10% K 2 CO 3 One time washing with the solution, one time washing with 88L of water88L 10% NaCl was washed once, and the organic layer was barreled and refrigerated. The invention adopts low-temperature reaction, can greatly reduce the adverse effect of the product on operators, and is beneficial to environmental protection. |
