文章以定边盐湖卤水为原料,通过将卤水脱色除杂并浓缩到一定程度,使溶液中的氯化镁富集,达到过饱和后将其冷却,从而析出六水氯化镁晶体,将晶体分离干燥得到产物,并对工艺条件进行了单因素试验。最佳工艺条件为:脱色剂是H2O2;250mL卤水需要用1mLH2O2;保温沉降温度105℃、时间2h;冷却结晶温度40℃、时间1h;干燥温度60℃、时间0.5h。
文章以定邊鹽湖滷水為原料,通過將滷水脫色除雜併濃縮到一定程度,使溶液中的氯化鎂富集,達到過飽和後將其冷卻,從而析齣六水氯化鎂晶體,將晶體分離榦燥得到產物,併對工藝條件進行瞭單因素試驗。最佳工藝條件為:脫色劑是H2O2;250mL滷水需要用1mLH2O2;保溫沉降溫度105℃、時間2h;冷卻結晶溫度40℃、時間1h;榦燥溫度60℃、時間0.5h。
문장이정변염호서수위원료,통과장서수탈색제잡병농축도일정정도,사용액중적록화미부집,체도과포화후장기냉각,종이석출륙수록화미정체,장정체분리간조득도산물,병대공예조건진행료단인소시험。최가공예조건위:탈색제시H2O2;250mL서수수요용1mLH2O2;보온침강온도105℃、시간2h;냉각결정온도40℃、시간1h;간조온도60℃、시간0.5h。
The paper adopts salt lake of Dingbian County as raw material, through the brine was decolorize, we should eliminate the impurity and concentrate it to a certain extent, making magnesium chloride enrich more. When it reaches supersaturating, we can make it cooling. Thus separate six water magnesium chloride crystals out, crystal was separated and dried to obtain the product titration can detect the content of six water magnesium chloride in the product and preparation conditions were investigated in this paper by experiments of single factor. The optimal preparation conditions are as follows: bleaching agent H2O2, 250 mL brine needs 1 mL H2O2; thermal precipitation temperature is 105 ℃, time 2 h; cooling crystallization temperature is 40 ℃, time 1 h; drying temperature is 60 ℃, time 0.5 h.
