Zambiri zoyambira
Thupi ndi mankhwala katundu
Zakuthupi
1) Katundu: Krustalo wopanda mtundu wa kiyubiki kapena ufa woyera granular.Ndiwopanda fungo, wamchere komanso owawa pang'ono.
2) Kachulukidwe (g/mL, 25 ° C) : 3.203;
3) Malo osungunuka (℃) : 755;
4) Malo otentha (° C, kuthamanga kwa mumlengalenga): 1390;
5) Refractive index: 1.6412;
6) Kung'anima (° C) : 1390
7) Kusungunuka: kumasungunuka mosavuta m'madzi (kusungunuka ndi 90.5g / 100ml madzi pa 20 ° C, kusungunuka ndi 121g / 100ml madzi pa 100 ° C), njira yamadzimadzi imakhala yosalowerera komanso yoyendetsa.
8) Kuthamanga kwa nthunzi (806 ° C): 1mmHg.
Mankhwala katundu
1) Anhydrous sodium bromide makhiristo amalowa mu njira ya sodium bromide pa 51 ℃, ndipo dihydrate imapangidwa pamene kutentha kumakhala kotsika kuposa 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Bromidi ya sodium ikhoza kusinthidwa ndi mpweya wa klorini kuti upereke bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromidi amachitira ndi anaikira sulfuric asidi kupanga bromine, ndiye, pansi pa zochita za asidi oxidizing amphamvu, sodium bromide akhoza oxidized ndi wopanda bromine.
2NaBr+3H2SO4 (yokhazikika) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide imatha kuchitapo kanthu ndi sulfuric acid kuti ipange hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Mu njira yamadzimadzi, sodium bromide imatha kuchitapo kanthu ndi ayoni asiliva kuti apange bromide yasiliva yachikasu yowala.
Br – + Ag + = AgBr kumanzere
6) Electrolysis ya sodium bromide mu chitsulo chosungunuka kuti apange mpweya wa bromine ndi sodium zitsulo.
2 nabr yamphamvu = 2 ndi + Br2
7) Sodium bromide amadzimadzi njira akhoza kupanga sodium bromate ndi haidrojeni ndi electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Zochita zakuthupi zimatha kuchitika, monga momwe zimachitikira popanga bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O
Zambiri zamalonda
Njira Zokonzekera
1) Njira ya mafakitale
Bromine yochulukirapo pang'ono imawonjezedwa mwachindunji ku saturated sodium hydroxide thermal solution kuti apange chisakanizo cha bromide ndi bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Chosakanizacho chimasungunuka kuti chiume, ndipo zotsalira zake zolimba zimasakanizidwa ndi tona ndikutenthetsa kuti bromate ikhale bromide:
NaBrO3 = NaBr + 3 c + 3 co lembani
Pomaliza, amasungunuka m'madzi, kenako amasefedwa ndikuwunikiridwa, ndikuwumitsa pa 110 mpaka 130 digiri Celsius.
*Njira imeneyi ndi njira wamba yopangira bromide ndi bromine ndipo imagwiritsidwa ntchito m'makampani.
2) Njira yosalowerera ndale
Gwiritsani ntchito sodium bicarbonate monga zopangira: Sungunulani sodium bicarbonate m'madzi, ndiyeno neutralize ndi 35% -40% hydrobromide kupeza sodium bromidi njira, amene condensed ndi utakhazikika kuti precipitate sodium bromide dihydrate.Sefa, sungunulani dihydrate ndi madzi pang'ono, dontho bromine madzi mpaka mtundu wa bromine imangoonekera mu anhydrogen aquelour solution, hydrogen aquelour solution kubweretsa anhydrogen aquelour solution. wiritsani.Pa kutentha kwakukulu, anhydrous crystallization precipitates, ndipo itatha kuyanika, imasamutsidwa ku chowumitsa ndikusungidwa pa 110 kwa ora la 1. Kenaka imakhazikika mu chowumitsa ndi calcium bromide desiccant kuti ipeze anhydrous sodium bromide (reagent grade).
Mfundo yochitira: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ndi 40% madzi amchere monga zopangira: kuika asidi hydrobromide mu zimene mphika, pansi yogwira ntchito nthawi zonse, pang`onopang`ono kuwonjezera 40% madzi alkali njira, neutralize kwa pH7.5 - 8.0, anachita kupanga sodium bromide solution.The sodium bromide njira anali centrifuged ndi osasankhidwa mu dilute sodium bromide njira yosungirako thanki. 1. 55 ° Khalani kapena kupitilira apo, kusefera kwa centrifugal, kusefera mu tanki yosungiramo madzi a sodium bromide. Kenako kukanikizidwa mu thanki ya crystallization, mu crystallization yolimbikitsa yoziziritsa, ndiyeno crystallization ya kulekana kwa centrifugal, mankhwala omalizidwa.
Mfundo yochitira: HBr+NaOH→NaBr+H2O
3) Njira yochepetsera urea:
Mu thanki ya alkali, soda imasungunuka m'madzi otentha pa kutentha kwa 50-60 ° C, ndiyeno urea.
amawonjezeredwa kuti asungunuke 21 ° Khalani yankho.Kenaka mumphika wochepetsera, pang'onopang'ono kupyolera mu bromine, sungani kutentha kwa 75-85 °C, mpaka pH ya 6-7, ndiko kuti, kufika kumapeto kwa zomwe zimachitika, siyani bromine ndi kuyambitsa, pezani sodium bromide solution.
Sinthani pH ku 2 ndi hydrobromic acid, ndiyeno sinthani pH ku 6-7 ndi urea ndi sodium hydroxide kuchotsa bromate. Njira yothetserayi imatenthedwa mpaka chithupsa ndipo njira yowonjezera ya barium bromide imawonjezedwa pa pH6 - 7 kuchotsa sulfate. maola. Njirayi itatha kufotokozedwa, imasefedwa, imatuluka mumlengalenga, ndipo zinthu zapakatikati zimadzazidwa kangapo. Siyani kudyetsa kwa maola a 2 musanayambe crystallization. Sinthani pH ku 6-7 1 ora musanayambe crystallization. Bromide ya sodium inalekanitsidwa ndikuwumitsidwa mu chowumitsa ng'oma yozungulira.
Mfundo yofunika kuchita: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
Mapulogalamu
Chithunzi cha Sodium Sulfite
1) Amagwiritsidwa ntchito pofufuza ndi kutsimikiza kwa tellurium ndi niobium ndikukonzekera njira yopangira mapulogalamu, yomwe imagwiritsidwanso ntchito ngati kuchepetsa;
2) Amagwiritsidwa ntchito ngati zopangidwa ndi anthu CHIKWANGWANI stabilizer, nsalu bleaching wothandizira, zithunzi kutukula, utoto ndi bleaching deoxidizer, kukoma ndi utoto kuchepetsa wothandizira, pepala lignin remover, etc.
3) Ntchito ngati wamba kusanthula reagent ndi photosensitive resistor zakuthupi;
4) Reductive bleaching agent, yomwe imakhala ndi blekning pa chakudya komanso imalepheretsa kwambiri oxidase muzakudya zamasamba.
5) Makampani osindikizira ndi opaka utoto monga deoxidizer ndi bulichi, omwe amagwiritsidwa ntchito pophika nsalu zosiyanasiyana za thonje, angalepheretse makutidwe ndi okosijeni am'deralo a ulusi wa thonje komanso kukhudza mphamvu ya fiber, komanso kuwongolera kuyera kwa zinthu zophika.
6) Amagwiritsidwa ntchito ndi makampani opanga nsalu ngati chokhazikika cha ulusi wopangidwa ndi anthu.
7) Makampani opanga zamagetsi amagwiritsidwa ntchito popanga ma photosensitive resistors.
8) Madzi mankhwala makampani electroplating madzi oipa, mankhwala akumwa madzi;
9) Amagwiritsidwa ntchito ngati bleach, preservative, kumasula wothandizila ndi antioxidant m'makampani azakudya. Amagwiritsidwanso ntchito mu kaphatikizidwe ka mankhwala komanso ngati chochepetsera pakupanga masamba osowa madzi.
10) Ntchito kupanga mapadi sulfite ester, sodium thiosulfate, mankhwala organic, bleached nsalu, etc., amagwiritsidwanso ntchito monga kuchepetsa wothandizila, preservative, dechlorination wothandizila, etc.;
11) Laboratory imagwiritsidwa ntchito popanga sulfure dioxide
