브롬시킨 천연의 6수염화마그네슘(MgCl2·6H2O)수용액을 암모니아 수용액이나 가스로 처리한 다음 침전물을 제거하고 그 부등액을 석회로 처리하여 석고 침전물을 분리제거하고 그 부등액을 전열부에서 가열 농축하여 생성된 침전물을 제거한 후 남은 부등액을 냉각조에서 냉각시켜 결정을 분리 제거한 다음 그 부등액을 다시 전열부에서 약 l34℃의 온도까지 탕비 농축시켜 방냉조에서 방냉하고 거기에서 생성된 염화마그네슘 결정을 분리, 탈수시켜 고순도의 염화마그네슘을 얻고 이를 가열하여 자체 가수분해 시킨 다음 다시 약 600℃까지 가열하여 고순도의 마그네시아를 얻은 후 이것을 약 15%의 수산화암모늄 수용액에서 1시간 이상 방치하여 고순도의 수산화마그네슘을 얻음을 특징으로 하는 고순도 수산화마그네슘의 제조방법.Treat the brominated natural magnesium hexachloride solution (MgCl 2 · 6H 2 O) with an aqueous ammonia solution or gas, remove the precipitate, and treat the unequal solution with lime to remove and remove the gypsum deposit. After removing the precipitate formed by heating and condensing at, the remaining liquid is cooled in a cooling tank to separate and remove the crystals, and then the liquid is concentrated again in the heat transfer section to a temperature of about l34 ° C. Magnesium chloride crystals are separated and dehydrated to obtain magnesium chloride of high purity, which is then heated and hydrolyzed by itself, and then heated to about 600 ° C. to obtain high purity magnesium, which is then left in an aqueous solution of about 15% ammonium hydroxide for at least 1 hour to obtain high purity. Method for producing high purity magnesium hydroxide, characterized in that to obtain magnesium hydroxide. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
