Kutumiza Mwachangu ku China Mchere Wabwino Wabwino Wam'nyanja Woyengedwa Kuti Utsukidwe ndi Matenda a Dziwe Losambira

Ndi ukadaulo wapamwamba komanso malo ogwirira ntchito, chogwirira chapamwamba kwambiri, mtengo wabwino, ntchito zapamwamba komanso mgwirizano wapafupi ndi makasitomala athu, tadzipereka kupereka mtengo wabwino kwambiri kwa makasitomala athu kuti atumizidwe mwachangu ku China. Mchere Wabwino Wokonzedwa Wabwino Kwambiri Woyeretsa Posambira. Mawonekedwe ndi mayankho onse adzayamikiridwa kwambiri! Mgwirizano waukuluwu ungathandize tonsefe kupita patsogolo kwambiri!
Ndi ukadaulo wapamwamba komanso malo ogwirira ntchito, chogwirira chapamwamba kwambiri, mtengo wololera, ntchito zapamwamba komanso mgwirizano wapafupi ndi makasitomala athu, tadzipereka kupereka mtengo wabwino kwambiri kwa makasitomala athu.Kuyeretsa Dziwe Losambira la ku China, Dziwe Losambira Lothira Matenda a Mchere, Mumsika womwe ukupikisana kwambiri, Ndi ntchito yowona mtima yogulitsa zinthu zapamwamba komanso mbiri yabwino, nthawi zonse timapereka chithandizo kwa makasitomala pazinthu ndi njira zopezera mgwirizano wanthawi yayitali. Kukhala ndi moyo wabwino, chitukuko ndi ngongole ndi ntchito yathu yamuyaya, Tikukhulupirira kuti mukadzabwera tidzakhala ogwirizana nanu kwanthawi yayitali.

Chidziwitso choyambira

Katundu wa thupi ndi mankhwala

Katundu Wathupi
1) Kapangidwe kake: Ufa wa kristalo wa cubic kapena woyera wopanda fungo, ndi wamchere komanso wowawa pang'ono.
2) Kuchulukana (g/mL, 25 ° C): 3.203;
3) Malo osungunuka (℃): 755;
4) Kuwira (° C, kuthamanga kwa mpweya): 1390;
5) Chizindikiro cha Refractive: 1.6412;
6) Malo owunikira (° 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), yankho lamadzi silili lopanda mbali komanso loyendetsa mpweya. Limasungunuka pang'ono mu mowa, limasungunuka mu acetonitrile, acetic acid.
8) Kuthamanga kwa nthunzi (806 ° C): 1mmHg.
Kapangidwe ka mankhwala
1) Makristalo a sodium bromide omwe alibe madzi amalowa mu sodium bromide solution pa 51℃, ndipo dihydrate imapangidwa kutentha kwake kuli kotsika kuposa 51℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide ikhoza kusinthidwa ndi mpweya wa chlorine kuti ipereke bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide imakumana ndi sulfuric acid yokhazikika kuti ipange bromine, ndiko kuti, pogwiritsa ntchito asidi wamphamvu wowonjezera, sodium bromide imatha kusungunuka ndikukhalabe ndi bromine.
2NaBr+3H2SO4 (yokhazikika) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide imatha kuchitapo kanthu ndi sulfuric acid yochepetsedwa kuti ipange hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Mu madzi, sodium bromide imatha kuchita ndi ma ayoni asiliva kuti ipange bromide yasiliva yolimba yachikasu yopepuka.
Br – + Ag + = AgBr kumanzere
6) Kukonza ma electrolysis a sodium bromide mu mkhalidwe wosungunuka kuti apange mpweya wa bromine ndi chitsulo cha sodium.
2 nabr yolimbikitsidwa = 2 na + Br2
7) Madzi a sodium bromide amatha kupanga sodium bromate ndi hydrogen pogwiritsa ntchito electrolysis.
NaBr + 3H2O= NaBrO3 yamagetsi + 3H2↑
8) Zochitika zachilengedwe zimatha kuchitika, monga momwe zimachitikira popanga bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

Tsatanetsatane wa malonda

Njira Zokonzekera

1) Njira ya mafakitale
Bromine wochuluka pang'ono amawonjezeredwa mwachindunji ku yankho lotentha la sodium hydroxide kuti apange chisakanizo cha bromide ndi bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Chosakanizacho chimasanduka nthunzi kuti chiume, ndipo zotsalira zolimba zomwe zimatuluka zimasakanizidwa ndi toner ndikutenthedwa kuti bromate ichepetse kukhala bromide:
NaBrO3 = NaBr + 3 c + 3 co write
Pomaliza, imasungunuka m'madzi, kenako imasefedwa ndi kupangidwa kukhala makristalo, kenako imaumitsidwa pa madigiri 110 mpaka 130 Celsius.
*Njira iyi ndi njira yodziwika bwino yopangira bromide ndi bromine ndipo nthawi zambiri imagwiritsidwa ntchito m'mafakitale.
2) Njira yochepetsera kufalikira kwa matenda
Gwiritsani ntchito sodium bicarbonate ngati zopangira: sungunulani sodium bicarbonate m'madzi, kenako muyichotse ndi 35%-40% hydrobromide kuti mupeze sodium bromide solution, yomwe imafupikitsidwa ndikuziziritsidwa kuti ipangitse sodium bromide dihydrate. Sefani, sungunulani dihydrate ndi madzi pang'ono, tsitsani madzi a bromine mpaka mtundu wa bromine utawonekera. Tenthetsani, sinthani mtundu mu yankho lamadzi la hydrogen sulfide, ndikuwiritsa. Pa kutentha kwakukulu, anhydrous crystallization imayamba, ndipo ikauma, imasamutsidwira ku chowumitsira ndikusungidwa pa 110 kwa ola limodzi. Kenako imaziziritsidwa mu chowumitsira chokhala ndi calcium bromide desiccant kuti mupeze anhydrous sodium bromide (reagent grade).
Mfundo yogwiritsira ntchito: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ndi 40% yamadzimadzi a alkali ngati zopangira: ikani hydrobromide acid mumphika wothira, pansi pa kusakaniza kosalekeza, onjezerani pang'onopang'ono 40% yamadzimadzi a alkali, chepetsani pH 7.5 - 8.0, chitani kuti mupange sodium bromide solution. Sodium bromide solution idayikidwa pakati ndikusefedwa mu thanki yosungiramo sodium bromide dilute. Kenako mu thanki yosungiramo evaporation, kudyetsa pakati 1-2, mpaka kukula kwa 1.55°C kapena kotero, centrifugal filtration, kusefedwa mu thanki yosungiramo sodium bromide. Kenako idakanikizidwa mu thanki yosungiramo crystallization, mu stirlization yozizira, kenako crystallization ya centrifugal learning, chinthu chomalizidwa. Mowa wa mayi umabwezeretsedwa ku thanki yosungiramo sodium bromide dilute.
Mfundo yokhudza kuyankha: HBr+NaOH→NaBr+H2O
3) Njira yochepetsera urea:
Mu thanki ya alkali, soda imasungunuka m'madzi otentha kutentha kwa 50-60 °C, kenako urea
imawonjezedwa kuti isungunuke yankho la 21°Be. Kenako mumphika wochepetsera reaction, pang'onopang'ono kudzera mu bromine, lamulirani kutentha kwa reaction kwa 75-85 °C, mpaka pH ya 6-7, ndiko kuti, kuti mufike kumapeto kwa reaction, siyani bromine ndikusakaniza, pezani sodium bromide solution.
Sinthani pH kufika pa 2 ndi hydrobromic acid, kenako sinthani pH kufika pa 6-7 ndi urea ndi sodium hydroxide kuti muchotse bromate. Yankho limatenthedwa mpaka kuwira ndipo yankho lodzaza la barium bromide limawonjezedwa pa pH6 — 7 kuti muchotse sulfate. Ngati mchere wa barium ndi wochuluka, sulfuric acid wochepetsedwa ukhoza kuwonjezeredwa kuti muchotse. Onjezani mpweya woyatsidwa ku zinthu zomwe zimachitika mutachotsa zonyansa, ndikuziyika kwa maola 4-6. Yankho likatha kufotokozedwa, limasefedwa, kusungunuka ndi mpweya pa mphamvu ya mlengalenga, ndipo zinthu zapakati zimadzazidwa kangapo. Siyani kudya kwa maola awiri musanayambe kupanga makristalo. Sinthani pH kufika pa 6-7 ola limodzi musanayambe kupanga makristalo. Sodium bromide inalekanitsidwa ndikuumitsidwa mu chowumitsira cha ng'oma chozungulira.
Mfundo yogwiritsira ntchito: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O

Mapulogalamu

Tchati cha Mayendedwe a Sodium Sulfite
