| titleOfInvention | PROCEDURE FOR THE RECONDITIONING BY DISTILLATION OF A METHANOL / WATER MIXTURE AND PROCEDURE FOR PREPARING METOXIDES OF ALKALIN METALS |
| abstract | A process for the reconditioning by distillation of a methanol / water mixture, in which a mixture of methanol / water is added to a distillation column (1), a vapor stream is drawn which essentially comprises methanol in the head of the distillation column (1) and a bottom stream that essentially comprises water at the bottom of the distillation column (1), at least a portion of the vapor stream that essentially comprises methanol is compressed and the steam stream is added compressed as steam for heating to an evaporator (11) in which at least a portion of the methanol / water mixture to be separated is evaporated. In addition, a process for preparing alkali metal methoxides in a reaction column (31) by adding methanol and alkali metal hydroxide solution to the reaction column (31), extracting alkali metal methoxide dissolved in methanol at the lower end of the reaction column (31) and extracting a methanol / water mixture at the upper end of the reaction column (31) and reconditioning the methanol / water mixture by the procedure for distillation reconditioning. |
