Description
Przy poddawaniu wypalonego dolomi¬ tu w zawiesinie wodnej dzialaniu gazów spalinowych lub dwutlenku wegla pod ci¬ snieniem magnez przechodzi do rozczynu jako kwasny weglan magnezowy.Mg(OH)2 + 2 C02 = Mg(HC03)2 Jesli te reakcje przeprowadzi sie w obec¬ nosci chlorku wapniowego, to zajdzie re¬ akcja nastepujaca: Mg(HC0J2 + Ca Cl2 = Mg Ct2 + + Ca C03 + C02 + H20.Reakcja ta przebiega najszybciej w tempe¬ raturze okolo 45°C, przy czym cisnienie gazów spalinowych lub dwutlenku wegla nalezy utrzymac na wysokosci 2 — 3 atmosfer. Do przeprowadzenia calej ilosci chlorku wapniowego w chlorek magnezo¬ wy wymagany jest pewien nadmiar wodo¬ rotlenku magnezowego. Po skonczonej re¬ akcji i odfiltrowaniu chlorku magnezowe¬ go rozczyn odparowuje sie otrzymujac czysty technicznie chlorek magnezowy. PL

Sposób wytwarzania chlorku magnezo¬ wego z dolomitu i chlorku wapniowego, znamienny tym, ze na zawiesine dolomitu palonego w roztworze chlorku wapniowe¬ go dziala sie gazami spalinowymi lub dwu¬ tlenkiem wegla w temperaturze normalnej lub podwyzszonej pod cisnieniem 2 — 3 atmosfer.
