| titleOfInvention | The production method of basic magnesium carbonate |
| abstract | The present invention discloses the production method of basic magnesium carbonate.Thick hydrazine preparation process, is reacted in reactor by urea solution and sodium hypochlorite and produces hydrazine hydrate, and for the thick hydrazine temperature in reactor at 100 degree -110 degree, accessory substance includes sodium chloride and sodium carbonate；Distilation steps, without cooling, squeeze into vapo(u)rization system heating distillation moisture by the thick hydrazine of high temperature, obtain distilling thick hydrazine；Settling step, adds magnesium chloride in thick hydrazine is distilled, magnesium chloride is chemically reacted with the sodium carbonate in thick hydrazine, produces precipitation；Separating step, with separator sediment separate out, obtains sediment and separating liquid；Basic magnesium carbonate step is prepared, the sediment that separating step is obtained is washed with industry water or steam condensate (SC), and mashing, by pyrolysis, prepares basic magnesium carbonate. |
