Sodium chloride, Kev lag luam ntsev, NaCl
Khoom Taw Qhia
Sodium chloride yog ib qho inorganic ionic compound, tshuaj NaCl, tsis muaj xim cubic siv lead ua los yog hmoov zoo crystalline, qab ntsev.Cov tsos yog dawb siv lead ua duab, nws qhov chaw yog dej hiav txwv, yog lub ntsiab ntawm ntsev.Soluble hauv dej, glycerol, me ntsis soluble hauv ethanol (cawv), kua ammonia;Insoluble nyob rau hauv concentrated hydrochloric acid.Impure sodium chloride muaj deliquescence hauv huab cua.Kev ruaj ntseg yog qhov zoo, nws cov tshuaj aqueous yog nruab nrab, kev lag luam feem ntau siv cov tshuaj electrolytic saturated sodium chloride los tsim hydrogen, chlorine gas thiab caustic soda (sodium hydroxide) thiab lwm yam khoom siv tshuaj (feem ntau hu ua chlor-alkali kev lag luam) tuaj yeem kuj tseem siv tau rau ore smelting (electrolytic fused sodium chloride siv lead ua los tsim active sodium hlau), kev kho mob siv los npaj physiological saline, Lub neej yuav siv tau rau condiments.

Kev lag luam thov
1.electrolytic sodium chloride tov, yuav tsim hydrogen thiab chlorine gas, chlorine gas muaj ntau yam kev siv nyob rau hauv chemical kev lag luam, yuav siv tau nyob rau hauv lub synthesis ntawm PVC, tshuaj tua kab, hydrochloric acid, thiab lwm yam.
2. Das txheej txheem rau sodium hlau: los ntawm electrolytic melting ntawm sodium chloride thiab calcium chloride sib tov los npaj sodium hlau.Calcium chloride yog siv los ua ib qho flux los txo qhov melting point ntawm sodium chloride kom qis dua 700 ℃.Calcium txo qis dua sodium thiab tsis qhia impurities.
3. sodium chloride yog qhov tsim nyog rau ntau yam tshuaj lom neeg lom neeg, xws li kev sim tshuaj lom neeg lom neeg hauv ntau hom tshuaj muaj sodium chloride, kab mob nruab nrab feem ntau muaj sodium chloride.Nyob rau tib lub sijhawm, nws kuj yog cov khoom siv raw ntawm soda tshauv txheej txheem.
4. inorganic thiab organic kev lag luam siv los ua raw khoom rau kev tsim cov caustic soda, chlorate, hypochlorite, bleaching hmoov, refrigerating system refrigerant, organic synthesis ntawm raw cov ntaub ntawv thiab salting tawm cov neeg ua hauj.Hlau thiab steel kev lag luam siv los ua tus neeg sawv cev kho cua sov.Qhov kub kub qhov chaw kub yog tov nrog potassium chloride, barium chloride thiab lwm yam ntsev da dej, uas tuaj yeem siv los ua cua sov nruab nrab kom tswj tau qhov kub ntawm 820 ~ 960 ℃.Tsis tas li ntawd, kuj siv rau hauv iav, zas xim, metallurgy thiab lwm yam lag luam.
5. analytical reagents siv fluorine thiab silicate trace analysis reagents.
6. Hou's caustic soda txoj kev: kauj ruam thib ob: thawj kauj ruam los npaj ammonium bicarbonate tov thiab sodium chloride tov tov, ntawm 10 ℃ kom tau sodium bicarbonate thiab ammonium chloride.
