I-sodium formate , eyaziwa nangokuthi i-sodium formate.I-sodium formate ingenye ye-organic carboxylates elula kakhulu. Ukubukeka kwayo amakristalu amhlophe noma i-powder enephunga elincane le-formic acid.I-hydrolytic kancane ne-hygroscopic.I-sodium formate isetshenziselwa ikakhulukazi ukukhiqizwa kwe-powder yomshuwalense, i-oxalic acid, ne-formic acid.I-formate ye-sodium ingasetshenziswa embonini yesikhumba njenge-camouflage acid kwinqubo yesikhumba se-chromium. Futhi ingasetshenziselwa i-catalyst kanye nokuzinzisa i-ejenti ye-synthesis, i-ejenti yokunciphisa embonini yokunyathelisa nokudaya.I-sodium formate ayinabungozi emzimbeni womuntu futhi ivuselela amehlo, uhlelo lokuphefumula kanye nesikhumba.
I-Sodium Formate ingusawoti wesisekelo esiqinile ne-asidi ebuthakathaka. Ngakho-ke ingasetshenziswa njengesivikelo ekugcineni i-pH.
I-sodium formate isetshenziswa ezinhlotsheni eziningi zokudaya nezinqubo zokuphrinta. Ibuye isetshenziswe njenge-ejenti ephazamisayo yama-acid amaminerali aqinile ukuze kwandiswe i-pH yawo, njengesengezo sokudla, nanjenge-ejenti yokususa uqhwa.
Kubhayoloji yesakhiwo, i-sodium formate ingasetshenziswa njenge-cryoprotectant yokuhlolwa kwe-X-ray diffraction kumakristalu amaprotheni, ngokuvamile okwenziwa ezingeni lokushisa elingu-100 K ukuze kwehliswe imiphumela yokulimala kwemisebe.
I-Sodium Formate eqinile isetshenziswa njenge-ejenti engagqwali ezikhumulweni zezindiza ukuze kukhishwe uqhwa kwemigwaqo yezindiza exutshwe nama-corrosion inhibitors nezinye izithasiselo, ezingena ngokushesha ezingqimbeni zeqhwa eziqinile, zizikhiphe ku-asphalt noma ukhonkolo futhi zincibilikise iqhwa ngokushesha. I-sodium formate nayo yasetshenziswa njenge-deicer yomgwaqo edolobheni lase-Ottawa kusukela ngo-1987 kuya ku-1988.
Ukucindezeleka kwephuzu eliphezulu lokuqandisa isib. uma kuqhathaniswa ne-urea esasetshenziswa njalo (esebenza kahle kodwa eyinkinga ngenxa ye-eutrophication) kuvimbela ngempumelelo ukuqhwaza kabusha, ngisho namazinga okushisa angaphansi kuka-−15 °C. Umthelela wokuncibilika wefomathi yesodium eqinile ungakhuliswa ngisho nokumanziswa nge-aqueous potassium formate noma izixazululo ze-potassium acetate. Ukonakala kwe-sodium formate kunenzuzo ikakhulukazi ngesidingo sekhemikhali komoyampilo (COD) esingu-211 mg O2/g uma kuqhathaniswa nama-de-icing agents e-sodium acetate (740 mg O2/g) kanye ne-urea ene-(> 2,000 mg O2/g).
Izixazululo ze-sodium egcwele i-formate (kanye nezingxube zezinye izakhiwo zensimbi ye-alkali njenge-potassium ne-cesium formate) zisetshenziswa njengezinsiza ezibalulekile zokumba nokuzinzisa ekuhloleni igesi namafutha ngenxa yokuminyana kwazo okuphezulu kakhulu. Ngokuxuba izixazululo ezihambisanayo ezigcwele ze-alkali zensimbi noma yikuphi ukuminyana phakathi kuka-1,0 no-2,3 g/cm3 kungasethwa. Izixazululo ezigcwele ziyi-biocidal futhi zizinzile isikhathi eside ngokumelene nokucekelwa phansi kwamagciwane. Ahlanjululwe, ngakolunye uhlangothi, ayashesha futhi angaboli ngokuphelele. Njengoba amafomethi ensimbi ye-alkali njengezinsiza zokumba akwenza kungadingeki ukwengeza izigcwalisi eziqinile ukuze kwandiswe ukuminyana (njengama-baryte) futhi izixazululo ze-formate zingatholwa futhi zisetshenziswe kabusha endaweni yokumba, amafomethi amelela intuthuko ebalulekile kubuchwepheshe bokuhlola.
i-sodium formate iyingozi.I-sodium formate ayinabungozi emzimbeni womuntu futhi ivuselela amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incwadi yokuphepha evela kusokhemisi be-Merck & Co. enesihloko esithi'Nitric Oxide at High Pressure' ichaze ukuqhuma okubili phakathi nokucindezeleka kokusabela phakathi kwe-NO ne-methanol ngaphansi kwezimo eziyisisekelo. Imikhiqizo ohlelweni lwemodeli ene-sodium methoxide yachazwa njenge-nitrous oxide ne-formic acid, mhlawumbe njenge-sodium formate. Ingozi engaba khona kulolu hlelo kufanele iboniswe: I-sodium formate idlula ukubola okushisayo ukuze inikeze igesi ye-hydrogen (J. Am. Chem. Soc,DOl: 10.1021/ja02245a004), eqhuma ngokuzenzakalelayo lapho kukhona i-nitrous oxide ngaphezu kwemikhawulo ebucayi, ngisho nalapho kungekho mthombo we-catalyst.
Ukuba khona kwe-hydrogen ne-nitrous oxide ngaphezu kwengxube yokusabela ngokungangabazeki kwaba yimbangela yokuqhuma nomlilo elabhorethri yami ngo-1981 ngesikhathi sokulungiswa kokusabela phakathi kwe-sodium ne-nitric oxide. Umkhiqizo omkhulu wokusabela yi-cissodium hyponitrite, ebola ngokushesha emanzini ukuze yakhe i-sodium hydroxide ne-nitrous oxide. Isisebenzi, esiyinhloko yebhayoloji esasishiswe kabi, senze lokhu izikhathi eziningi ngaphandle kwesigameko. Ngalesi sikhathi wazama kabili futhi wehluleka ukuhlakaza cishe u-30 g we-sodium ku-toluene futhi, ngaphandle kokubonisana nami, wanquma ukuqhubeka nokusabela. Ukuqhuma kwenzeke ngesikhathi ezama ukucekela phansi i-sodium engaphenduliwe, isigaxa esikhulu kakhulu ukuthi singasuswa eflaskini, ngokufaka amanzi adonsela phansi. Iningi le-sodium lalisabele ngesikhathi sokuqhuma, futhi kwakungekho inkomba yokwehluleka kwemishini. Ngaleso sikhathi, ngangingazi ngokungahambelani okukhulu kwamagesi amabili, futhi ingozi yayidida kakhulu. Ingxube yokusabela yayiseduze nezinga lokushisa legumbi futhi yanyakaziswa ngokushesha ngenkathi indawo yasekhanda ishaywa ngomfudlana we-nitrogen.
Nini | ifike elabhorethri emizuzwini embalwa ngemuva kwengozi, i-nitrogen yayisageleza iphuma ekugcineni okushile kwamashubhu epulasitiki. Kusukela ngaleso sikhathi, ngabona kubhekiselwa'kokuqhuma kwe-hydrogen' ezincwadini zamakhemikhali zasendulo njengendlela yokuhlonza i-nitrous oxide.
