| titleOfInvention | Process for preparing sulphuric methacrylamide and device for implementing it |
| abstract | The invention relates to a process for preparing sulphuric methacrylamide from acetone cyanohydrin. n This process for preparing sulphuric methacrylamide comprises: n a) a mixing step, in which acetone cyanohydrin is mixed with sulphuric acid; n b) a stoving step; n c) a step of adding further acetone cyanohydrin; n d) another stoving step; n e) optionally, one or more additional step(s) of further addition of acetone cyanohydrin followed by an additional stoving step; and n f) optionally, a final stoving step. n It is characterized in that sulphur trioxide is also introduced in step c) and/or just after this step c) and/or, where appropriate, in one or more of the additional steps of further addition e) and/or just after this or these step(s) e). n The invention also relates to a device for carrying out this process. |
