Ukusetshenziswa kwe-sulfamic acid kanye nokuhlanganiswa
| Chemical Properties | I-Sulfamic acid iyikristalu emhlophe ye-orthorhombic ene-flaky, engenaphunga, engaguquguquki futhi engeyona i-hygroscopic.Incibilika emanzini ne-ammonia ewuketshezi, inyibilika kancane ku-methanol, ayincibiliki ku-ethanol ne-ether, futhi ayincibiliki ku-carbon disulfide kanye ne-liquid sulfur dioxide.Isixazululo saso esinamanzi sinezici ze-asidi eqinile njenge-hydrochloric acid ne-sulfuric acid, kodwa ukugqwala kwayo ezinsimbi kuphansi kakhulu kune-hydrochloric acid.Ubuthi buncane kakhulu, kodwa akufanele buthintane nesikhumba isikhathi eside, futhi akufanele bungene emehlweni. |
| Isebenzisa | I-Sulfamic acid isetshenziswa kakhulu ekufakweni kwe-electroplating, ekususeni isikali samanzi aqinile, i-ejenti yokuhlanza i-asidi, iziqinisi ze-chlorine, ama-sulfonating agents, ama-denitrification agents, ama-disinfectants, ama-flame retardants, ama-herbicides, ama-sweeteners okwenziwa kanye nama-catalysts. I-Sulfamic acid iyisandulela senhlanganisela yokunambitha okumnandi.Ukusabela nge-cyclohexylamine okulandelwa ukwengezwa kwe-NaOH kunikeza i-C6H11NHSO3Na, i-sodium cyclamate. I-Sulfamic acid iyi-asidi encibilikayo emanzini, eqinile ngokumaphakathi.Iphakathi phakathi kwe-sulfuric acid ne-sulfamide, ingasetshenziswa njengesandulela sezinhlanganisela ezinambitheka kamnandi, isakhi semithi yokwelapha, i-ejenti yokuhlanza ene-asidi, kanye ne-catalyst ye-esterification. |
| Isicelo | I-Sulfamic acid, i-monoamide ye-sulfuric acid, iyi-asidi ye-inorganic eqinile.Ngokuvamile isetshenziswa ezinqubweni zokuhlanza amakhemikhali njengokususwa kwe-nitrites, i-carbonate- ne-phosphate-containing deposits. I-Sulfamic acid ingasetshenziswa njenge-catalyst ku: I-Friedlander quinoline synthesis. Ukuhlelwa kabusha kwe-Liquid Beckmann kokuhlanganiswa kwama-amide kusuka kuma-ketoxime. Ukulungiswa kwe-α-aminophosphonates ngokusabela kwezingxenye ezintathu phakathi kwe-aldehydes, ama-amines, ne-diethyl phosphite. |
| Incazelo | I-ChEBI: I-Sulfamic acid iyi-asidi ye-sulfamic elula kunazo zonke ehlanganisa i-athomu eyodwa yesibabule eboshwe ngokuhlanganyela ngebhondi eyodwa kumaqembu e-hydroxy nama-amino kanye namabhondi aphindwe kabili kuma-athomu amabili omoya-mpilo.I-asidi eqinile, yakheka kalula usawoti we-sulphamate, oncibilika kakhulu emanzini futhi ovame ukuba khona njenge-zwitterion H3N+.SO3–. |
| Ukusabela | I-Sulfamic acid iyi-asidi eqinile esabela ngezinhlanganisela eziningi eziyisisekelo.Ishiselwa ngaphezu kwendawo yokuncibilika (209°C) ngaphansi kwengcindezi evamile ukuze iqale ukubola, futhi iyaqhubeka nokushisisa ibe ngaphezu kuka-260°C ukuze ibole ibe yi-sulphur trioxide, i-sulphur dioxide, i-nitrogen, i-hydrogen namanzi. (1) I-sulfamic acid ingasabela nezinsimbi ukuze yakhe usawoti ocwebezelayo oyikristale.Njenge: 2H2NSO3H+Zn→Zn(SO3NH2)2+H2. (2) Ingasabela nge-metal oxides, carbonates nama-hydroxides: FeO+2HSO3NH2→Fe(SO3NH2)2+H2O2 I-CaCO3+2HSO3NH2→Ca(SO3NH2)2+H2O+CO23 Ni(OH)2+2HSO3NH2→Ni(SO3NH2)2+H2O. (3) Ingasabela nge-nitrate noma i-nitrite: HNO3+HSO3NH2→H2SO4+N2O+H2O2 HNO2+HSO3NH2→H2SO4+N2+H2O. (4) Ingasabela ngama-oxidants (njenge-potassium chlorate, i-hypochlorous acid, njll.): KClO3+2HSO3NH2→2H2SO4+KCl+N2+H2O2 2HOCl+HSO3NH2→HSO3NCl2+2H2O |
| Incazelo evamile | I-Sulfamic acid ibonakala njenge-crystalline solid solid.Ukuminyana 2.1 g/cm3.Iphuzu lokuncibilika lingu-205°C.Okuvuthayo.Kucasula isikhumba, amehlo, nolwelwesi lwamafinyila.Ubuthi obuphansi.Isetshenziselwa ukwenza odayi namanye amakhemikhali.Isetshenziswa njengento eluhlaza ekulungiseni i-sweetener yokwenziwa okungukuthi, i-sodium cyclohexylsulfamate. |
| Ukusabela Komoya Namanzi | Incibilika ngokulingene emanzini [Hawley]. |
| Iphrofayela Yokuphinda Isebenze | I-Sulfamic acid isabela ngendlela exakile nezisekelo.Izixazululo ezinamanzi zine-asidi futhi ziyagqwala. |
| Ingozi | Ubuthi ngokumunca. |
| Ingozi Yezempilo | OKUNOBUTHI;ukuhogela umoya, ukumunca noma ukuthintana kwesikhumba ngento kungabangela ukulimala okubi kakhulu noma ukufa.Ukuthintana nezinto ezincibilikisiwe kungabangela ukusha okukhulu esikhumbeni nasemahlweni.Gwema noma yikuphi ukuthintana kwesikhumba.Imiphumela yokuxhumana noma ukuhogela ingase ibambezeleke.Umlilo ungase ukhiqize amagesi acasulayo, abolayo kanye/noma anobuthi.Ukugeleza kwamanzi okulawula umlilo noma amanzi ahlanjululwayo kungase kudle futhi/noma kube nobuthi futhi kubangele ukungcola. |
| Ingozi Yomlilo | Into engashi, yona ngokwayo ayishi kodwa ingase ibole lapho ishiswa ukuze ikhiqize intuthu ebolayo kanye/noma enobuthi.Ezinye zingama-oxidizer futhi zingase zithungele izinto ezivuthayo (ukhuni, iphepha, uwoyela, izingubo zokugqoka, njll.).Ukuthintana nezinsimbi kungase kuvele igesi ye-hydrogen evuthayo.Iziqukathi zingaqhuma uma zishisiwe. |
| Ukuvutha nokugqama | Okungashi |
| Iphrofayela Yokuphepha | Ubuthi ngomzila we-intraperitoneal.Inobuthi obumaphakathi ngokumunca.Isikhumba somuntu esicasulayo.Ukucasula okulimazayo esikhumbeni, emehlweni, nolwelwesi lwamafinyila.Into ethuthela ekudleni isuka ezintweni zokupakisha.Ukusabela okunobudlova noma ukuqhuma nge-chlorine, i-nitrate yensimbi + ukushisa, i-metal nitrites + ukushisa, i-HNO3 evuthayo.Uma ishiselwa ukuze ibole ikhipha intuthu enobuthi kakhulu ye-SOx ne-NOx.Bheka nelithi SULFONATES. |
| Okungase kube ukuchayeka | I-Sulfamic acid isetshenziselwa ukuhlanza insimbi ne-ceramic, i-bleaching paper pulp;kanye nezindwangu zensimbi;ekuhlanzeni i-asidi;njenge-ejenti yokuzinza ye-chlorine ne-hypochlorite emachibini okubhukuda;ukupholisa imibhoshongo;nezigayo zephepha. |
| Ukuthumela ngomkhumbi | I-UN2967 i-Sulfamic acid, isigaba se-Hazard: 8;Amalebula: 8-Ebolayo. |
| Izindlela Zokuhlanza | I-Crystallize NH2SO3H emanzini angu-70o (300mL ngo-25g), ngemva kokuhlunga, ngokupholisa kancane futhi ulahle iqoqo lokuqala lamakristalu (cishe u-2.5g) ngaphambi kokuma kungxube yeqhwa nosawoti imizuzu engu-20.Amakristalu ahlungwa ngokumuncwa, agezwe ngamanzi abandayo eqhwa kabili, bese kabili nge-EtOH ebandayo futhi ekugcineni nge-Et2O.Yomise emoyeni ihora elingu-1, bese uyigcina ku-desiccator ngaphezu kwe-Mg(ClO4)2 [Butler et al.Ind Eng Chem (Anal Ed) 10 690 1938].Ukuze uthole ukulungiselelwa kokubalulekile okujwayelekile bheka i-Pure Appl Chem 25 459 1969. |
| Ukungahambisani | Isixazululo esinamanzi yi-asidi eqinile.Isabela ngobudlova nama-asidi aqinile (ikakhulukazi i-nitric acid evuthayo), izisekelo, i-chlorine.Isabela kancane emanzini, yenze i-ammonium bisulfate.Ukungahambisani ne-ammonia, ama-amine, i-isocyanates, i-alkylene oxides;epichlorohydrin, oxidizers. |
