Nga korero taketake
Te āhuatanga o te tinana me te matū
Āhuatanga ā-tinana
1) Nga Ahuatanga: He karaehe putorino taekore, he paura maramara ma ranei.Kare he kakara, he tote me te paku kawa.
2) Kiato (g/mL, 25 ° C): 3.203;
3) Ira whakarewa (℃): 755;
4) Kohuatanga (° C, te pehanga hau): 1390;
5) Taupū Refactive: 1.6412;
6) Ira hiko (° C): 1390
7) Wairewa: he ngawari te wairewa i roto i te wai (ko te wairewa 90.5g / 100ml wai i te 20 ° C, ko te wairewa 121g / 100ml wai i te 100 ° C), ko te wairewa wai he kupapa me te conductive.He iti te wairewa i roto i te waipiro, te whakarewa i te acetonitrile, te waikawa acetic.
8) Te pehanga kohu (806 ° C): 1mmHg.
Ngā āhuatanga matū
1) Ko nga tioata konutai bromide anhydrous ka heke i roto i te otinga konutai bromide i te 51 ℃, ka hangaia te dihydrate ina he iti iho te pāmahana i te 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Ka taea te whakakapi i te konutai bromide ki te hau maaota hei hoatu bromine.
2Br-+Cl2=Br2+2Cl-
3) Ka tauhohe te konutai bromide ki te waikawa sulfuric concentrated hei whakaputa i te bromine, ara, i raro i te mahi a te waikawa oxidizing kaha, ka taea te konutai bromide te waikura me te kore he bromine.
2NaBr+3H2SO4 (kukū) =2NaHSO4+Br2+SO2↑+2H2O
4) Ka taea e te konutai bromide te tauhohe me te waikawa sulfuric dilute hei whakaputa i te hauwai bromide.
NaBr+H2SO4=HBr+NaHSO4
5) I roto i te wairewa wai, ka taea e te konutai bromide te tauhohe me nga katote hiriwa hei hanga i te bromide hiriwa totoka kowhai marama.
Br – + Ag + = AgBr ka mahue
6) Te hiko o te konutai bromide i roto i te ahua rewa ki te whakaputa hau bromine me te konutai konutai.
2 nabr kaha = 2 na + Br2
7) Ko te konutai bromide wairewa wai ka taea te whakaputa konutai bromate me te hauwai ma te hikohiko.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Ka puta nga tauhohenga waro, penei i te tauhohenga matua ki te hanga bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O
Taipitopito hua
Nga Tikanga Whakaritenga
1) Tikanga Ahumahi
Ko te bromine paku te taikaha ka honoa ki te waiariki waiariki konutai konutai ki te whakaputa i te ranunga o te bromide me te bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Ka whakaeto te ranunga kia maroke, ka konatunatua te toenga totoka ki te toner ka whakamahana hei whakaiti i te bromate ki te bromide:
NaBrO3 = NaBr + 3 c + 3 tahi tuhi
Ka mutu, ka rewa ki te wai, ka tātarihia, ka whakamarokehia, ka whakamaroke ki te 110 ki te 130 nga nekehanga Celsius.
*Ko tenei tikanga te tikanga whaanui mo te whakarite bromide ma te bromine ka whakamahia i roto i te umanga.
2)Te tikanga whakakore
Whakamahia te konutai bicarbonate hei rauemi mata: whakakorehia te konutai bicarbonate i roto i te wai, katahi ka whakakorehia ki te 35%-40% hydrobromide ki te tiki i te wairewa konutai bromide, ka whakapoapoa, ka whakamataohia kia tohe ai te konutai bromide dihydrate.Tatarihia, whakakorehia te dihydrate me te iti o te wai, maturuturu te wai bromine tae noa ki te tae o te wairewa heatqueous o te bromine me te hauwai. ki te whewhe.I te teitei o te pāmahana, ka heke te whakamaroke anhydrous, a, i muri i te whakamaroketanga, ka whakawhitia ki te whakamaroke ka pupuri i te 110 mo te 1 haora. Ka whakamataohia i roto i te whakamaroke me te konupūmā bromide desiccant ki te whiwhi konutai konutai bromide (koeke reagent).
Tikanga tauhohenga: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ki te 40% wai alkali hei rauemi mata: hoatu te waikawa hydrobromide ki roto i te kohua tauhohenga, i raro i te whakaoho tonu, ata taapirihia te 40% wairewa alkali wai, whakakore ki te pH7.5 - 8.0, tauhohe ki te whakaputa i te konutai bromide solution.I centrifuged te otinga konutai bromide ka tātarihia ki te waimeha konutai bromide otinga rokiroki tank. 1. 55°Kia ranei, filtration centrifugal, filtration ki te konutai bromide wai rokiroki tank.Na ka aki ki te tank whātioatanga, i roto i te whakakorikori whakamatao whātioatanga, a ka te whātioatanga o te wehenga centrifugal, te hua oti.Ko te whaea waipiro kua whakahokia ki te waimeha wai konutai bromide tank rokiroki wai.
Tikanga tauhohenga: HBr+NaOH→NaBr+H2O
3) Tikanga whakaheke Urea:
I roto i te tank alkali, ka rewa te houra ki te wai wera i te mahana o te 50-60 °C, katahi ka urea.
ka tapirihia ki te whakakore i te 21°Be solution.Na ki roto i te kohua tauhohenga whakaheke, ma te puhoi ma te puhoi, whakahaere i te pāmahana tauhohenga o te 75-85 °C, ki te pH o 6-7, ara, kia tae ki te mutunga o te tauhohenga, whakamutua te bromine me te whakakorikori, whiwhi otinga konutai bromide.
Whakaritea te pH ki te 2 me te waikawa hydrobromic, ka whakatika i te pH ki te 6-7 me te Urea me te konutai waikawa hei tango i te bromate.Ka whakamahanahia te otinga ki te whewhe, ka tapirihia he otinga kukū o te barium bromide ki te pH6 - 7 hei tango i te sulfate.Ki te nui te tote barium, ka taea te taapiri i te waikawa pungatara waimeha ki te tango. 4-6 haora. I muri i te whakamaaramatanga o te otinga, ka tātarihia, ka whakaeto i te pehanga hau, ka whakakiia te rauemi takawaenga i nga wa maha. Kati te kai mo te 2 haora i mua i te whakamaroketanga.Whakaritea te pH ki te 6-7 1 haora i mua i te whakamaaramatanga.I wehea te konutai bromide ka whakamarokehia i roto i te whakamaroke pahū hurihuri.
Tikanga o te tauhohenga: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
