I-sodium bicarbonate, ifomula yamangqamuzana ithi NAHCO₃, iyinhlanganisela ye-inorganic, ene-crystalline powder emhlophe, ayinaphunga, inosawoti, incibilika kalula emanzini.Ukubola kancane kancane emoyeni oswakeme noma emoyeni oshisayo, khiqiza i-carbon dioxide, bese ushisa kufika ku-270 ° C ubole ngokuphelele.Lapho ine-asidi, ibola kakhulu, ikhiqize isikhutha.
I-sodium bicarbonate isetshenziswa kabanzi mayelana nokuhlaziywa kwamakhemikhali, ukuhlanganiswa kwe-inorganic, ukukhiqizwa kwezimboni, ukukhiqizwa kwezolimo nokufuywa kwezilwane.
Izinto ezibonakalayo:i-sodium bicarbonateiyikristalu emhlophe, noma amakristalu e-opaque monocliplative angamakristalu amancane, angewona iphunga, anosawoti kancane futhi apholile, futhi ancibilika kalula emanzini ne-glycerin, futhi angancibiliki ku-ethanol.Ukuncibilika emanzini ngu-7.8g (18℃), 16.0g (60℃), ukuminyana kungu-2.20g/cm3, ingxenye ingu-2.208, inkomba ye-refractive ingu-α: 1.465;β: 1.498;γ: 1.504, i-entropy evamile engu-24.4J/(mol · K), ikhiqiza ukushisa okungu-229.3kj/mol, ukushisa okuncibilikisiwe okungu-4.33kj/mol, kanye nomthamo oshisayo (Cp）20.89J/(mol·°C)(22°C) .
Izakhiwo zamakhemikhali:
1. I-Acid ne-alkaline
Isixazululo esinamanzi se-sodium bicarbonate sine-alkaline ebuthakathaka ngenxa ye-hydrolysis: HCO3-+H2O⇌H2CO3+OH-, 0.8%inani le-pH yesisombululo esinamanzi ngu-8.3.
2. Sabele nge-asidi
I-sodium bicarbonate ingasabela nge-asidi, njenge-sodium bicarbonate ne-hydrochloride: nahco3+HCL = NaCl+CO2 ↑+H2O.
3. Ukusabela ku-alkali
I-sodium bicarbonate ingasabela nge-alkali.Isibonelo, i-sodium bicarbarbonate ne-sodium hydroxide reaction: nahco3+naOh = Na2CO3+H2O;kanye nokusabela kwe-calcium hydroxide, uma inani le-sodium bicarbonate ye-sodium ligcwele, kukhona: 2NAHCO3+CA (OH) 2 = CACO3 ↓+NA2CO3+2H2O;
Uma kunenani elincane le-sodium bicarbonate, kukhona: Nahco3+CA (OH) 2 = CACO3 ↓+Naoh+H2O.
4. Ukusabela kusawoti
A. I-sodium bicarbonate ingakwazi ukuphinda kabili i-hydrolysis nge-aluminium chloride ne-aluminium chloride, futhi ikhiqize i-aluminium hydroxide, usawoti wesodium kanye ne-carbon dioxide.
3AHCO3+AlCl3 = Al (OH) 3 ↓+3ACL+3CO2 ↑;3AHCO3+Al (CLO3) 3 = Al (OH) 3 ↓+3AClo3+3CO2 ↑.
B. I-sodium bicarbonate ingasabela ngezixazululo ezithile zikasawoti wensimbi, njenge: 2HCO3-+Mg2+= CO2 ↑+MgCo3 ↓+H2O.
5. Ukubola ngokushisa
Imvelo ye-sodium bicarbonate izinzile ezingeni lokushisa, futhi kulula ukuyihlephula.Ibola ngokushesha ngaphezu kuka-50 ° C. Ku-270 ° C, i-carbon dioxide ilahlekile ngokuphelele.Alukho ushintsho emoyeni owomile futhi ukubola kancane kancane emoyeni oswakeme.Ukubola Izibalo zokusabela: 2NAHCO3NA2CO3+CO2 ↑+H2O.
Inkambu yohlelo lokusebenza:
1. Ukusetshenziswa kwaselabhorethri
I-sodium bicarbonateisetshenziswa njengama-reagents okuhlaziya futhi isetshenziselwa ukuhlanganiswa kwe-inorganic.Ingasetshenziselwa ukulungisa isisombululo sebhafa se-sodium carbonate-sodium bicarbonate.Uma wengeza inani elincane le-asidi noma i-alkali, ingagcina ukuhlangana kwama-ion e-hydrogen ngaphandle kwezinguquko ezibalulekile, okungagcina inani le-pH lesistimu lizinzile ngokuqhathaniswa.
2. Ukusetshenziswa kwezimboni
I-sodium bicarbonate ingasetshenziswa ukukhiqiza izicishamlilo ze-pH kanye nezicisha-mlilo eziyigwebu, futhi i-sodium bicarbonate embonini yenjoloba ingasetshenziselwa ukukhiqizwa kwenjoloba nesipontshi.I-sodium bicarbonate embonini ye-metallurgical ingasetshenziswa njenge-ejenti encibilikayo yokuphonsa izinsimbi zensimbi.I-sodium bicarbonate embonini yemishini ingasetshenziswa njengomsizi wokubumba we-cast steel (amasemishi) isihlabathi.I-sodium bicarbonate embonini yokunyathelisa nokudaya ingasetshenziswa njenge-ejenti yokulungisa umbala, i-asidi -base buffer, kanye ne-ejenti yokwelapha engemuva edaywa ngendwangu ekunyatheliseni amabala;ukwengeza i-soda ekudayeni kungavimbela i-gauze ku-gauze.Ukuvimbela.
3. Ukusetshenziswa kokucubungula ukudla
Ekucutshungulweni kokudla, i-sodium bicarbonate iyi-ejenti exekethile esetshenziswa kakhulu esetshenziselwa ukukhiqiza amabhisikidi nesinkwa.Umbala uphuzi -nsundu.Kuyi-carbon dioxide esiphuzweni sesoda;ingahlanganiswa ne-alum ku-alkaline fermented powder, noma ingakhiwa ama-citromes njenge-alkali yamatshe avamile;kodwa futhi njenge-ejenti yokulondoloza ibhotela.Ingasetshenziswa njenge-ejenti yombala wezithelo nemifino ekucubunguleni imifino.Ukwengeza cishe u-0.1% kuya ku-0.2% we-sodium bicarbonate lapho ugeza izithelo nemifino kungazinzisa okuluhlaza.Lapho i-sodium bicarbonate isetshenziswa njenge-ejenti yokwelapha izithelo nemifino, ingakhuphula inani le-pH lezithelo nemifino ngokupheka izithelo nemifino, okungakhuphula inani le-pH lezithelo nemifino, kuthuthukise ukubanjwa kwamanzi amaprotheni, kukhuthaze ukuthambisa. amangqamuzana ezicubu zokudla, futhi ancibilikise izakhi ze-astringent.Ngaphezu kwalokho, kunomphumela obisini lwembuzi, ngenani lokusetshenziswa kuka-0.001%~ 0.002%.
4. Ezolimo kanye nemfuyo
I-sodium bicarbonateingasetshenziselwa ukucwiliswa kwezolimo, futhi ingenza futhi ukuntuleka kokuqukethwe kwe-lysine kokuphakelayo.I-sodium bicarbonate encibilikayo enanini elincane lamanzi noma izixube ku-concentrate ukondla inyama yenkomo (inani elifanele) ukukhuthaza ukukhula kwenyama yenkomo.Kungase futhi kukhulise kakhulu ukukhiqizwa kobisi lwezinkomo zobisi.
5. Ukusetshenziswa kwezokwelapha
I-sodium bicarbonate ingasetshenziswa njengempahla eluhlaza kwezemithi, esetshenziselwa ukwelapha i-asidi yesisu eyeqile, ubuthi be-metabolic acid, futhi ingakwazi nomchamo we-alkali ukuvimbela amatshe e-uric acid.Kunganciphisa futhi ubuthi bezinso bezidakamizwa ze-sulfa, futhi kuvimbele i-hemoglobin ukuthi ingangeni ku-tubular yezinso lapho i-hemolysis ebukhali, futhi yelaphe izimpawu ezibangelwa i-asidi yesisu ngokweqile;umjovo nge-intravenous awuqondile ubuthi bezidakamizwa Umphumela wokwelapha.Ikhanda elibuhlungu eliqhubekayo, ukulahlekelwa ukudla, isicanucanu, ukuhlanza, njll.
Inothi lesitoreji nezokuthutha: I-sodium bicarbonate iwumkhiqizo ongeyona ingozi, kodwa kufanele ivinjwe ekumswakama.Gcina ethangini elomile lokungenisa umoya.Ungaxubani ne-asidi.Isoda yokubhaka edliwayo akumele ihlanganiswe nezinto ezinobuthi ukuvikela ukungcola.
