Ukusetyenziswa kwe-asidi ye-sulfamic kunye ne-Synthesis

Iipropati zeMichiza	I-asidi ye-Sulfamic yikristale emhlophe ye-orthorhombic ene-flaky, engenavumba, i-non-volatile kunye ne-non-hygroscopic.Inyibilika emanzini nakwi-ammonia elulwelo, inyibilika kancinane kwi-methanol, ayinyibiliki kwi-ethanol nakwi-ether, nayo ayinyibiliki kwikhabhoni disulfide kunye ne-liquid sulfur dioxide.Isisombululo sayo samanzi sineempawu ze-asidi ezomeleleyo ezifana ne-hydrochloric acid kunye ne-sulfuric acid, kodwa ukubola kwayo kwiintsimbi kuphantsi kakhulu kune-hydrochloric acid.Ubuthi buncinci kakhulu, kodwa akufanele budibane nolusu ixesha elide, kwaye akufanele lungene emehlweni.
Usebenzisa	I-asidi ye-Sulfamic isetyenziswa ngokubanzi kwi-electroplating, i-removers yamanzi anzima, i-agent yokucoca i-acidic, i-chlorine stabilizers, i-sulfonating agents, i-denitrification agents, ii-disinfectants, i-flame retardants, i-herbicides, i-sweeteners eyenziweyo kunye ne-catalysts. I-asidi ye-Sulfamic isandulela kwiikhompawundi zokungcamla okuswiti.Ukusabela nge-cyclohexylamine elandelwa ngokongezwa kwe-NaOH inika i-C6H11NHSO3Na, i-sodium cyclamate. Iasidi yeSulfamic yiasidi enyibilikayo emanzini, eyomeleleyo ngokuphakathi.Indawo ephakathi phakathi kwe-asidi ye-sulfuric kunye ne-sulfamide, ingasetyenziselwa njenge-precursor kwi-sweet-tasting compounds, icandelo leyeza zonyango, i-agent yokucoca i-acidic, kunye ne-catalyst ye-esterification.
Isicelo	Iasidi ye-Sulfamic, i-monoamide ye-asidi ye-sulfuric, yi-asidi eyomeleleyo ye-inorganic.Ngokuqhelekileyo isetyenziswa kwiinkqubo zokucoca iikhemikhali ezifana nokususwa kwee-nitrites, carbonate- kunye ne-phosphate-containing deposits. I-asidi ye-Sulfamic ingasetyenziswa njenge-catalyst kwi: Friedlander quinoline synthesis. Ulwelo lwe-Beckmann uhlengahlengiso lokudityaniswa kwe-amide ukusuka kwi-ketoximes. Ukulungiswa kwe-α-aminophosphonates ngokuphendula kwamacandelo amathathu phakathi kwe-aldehydes, i-amines, kunye ne-diethyl phosphite.
Ingcaciso	I-ChEBI: Iasidi ye-Sulfamic yeyona ilula kwiiasidi zesulfamic equka iathom enye yesulfure ebotshelelwe ngokudibeneyo ngamabhondi e-hydroxy kunye namaqela e-amino kunye neebhondi ezimbini kwiiathom ezimbini ze-oxygen.Yiasidi eyomeleleyo, eyenza iityuwa zesulphamate ngokulula, enyibilika ngokugqithisileyo emanzini kwaye iqhele ukubakho njenge zwitterion H3N+.SO3–.
Iimpendulo	Iasidi ye-Sulfamic yi-asidi eyomeleleyo esebenza kunye neekhompawundi ezininzi ezisisiseko.Ifudunyezwa ngaphezu kwendawo yokunyibilika (209 ° C) phantsi koxinzelelo oluqhelekileyo ukuba iqale ukubola, kwaye iyaqhubeka ishushu ngaphezu kwe-260 ° C ukubola kwi-sulphur trioxide, i-sulphur dioxide, i-nitrogen, i-hydrogen kunye namanzi. (1) Iasidi ye-Sulfamic inokusabela ngeentsimbi ukwenza iityuwa zekristale ecacileyo.Njenge: 2H2NSO3H+Zn→Zn(SO3NH2)2+H2. (2) Inokusabela ngeeoksidi zetsimbi, iikhabhonithi kunye neehydroxides: FeO+2HSO3NH2→Fe(SO3NH2)2+H2O2 CaCO3+2HSO3NH2→Ca(SO3NH2)2+H2O+CO23 Ni(OH)2+2HSO3NH2→Ni(SO3NH2)2+H2O. (3) Unokusabela nge-nitrate okanye i-nitrite: HNO3+HSO3NH2→H2SO4+N2O+H2O2 HNO2+HSO3NH2→H2SO4+N2+H2O. (4) Inokusabela ngee-oxidants (ezifana ne-potassium chlorate, i-hypochlorous acid, njl.): KClO3+2HSO3NH2→2H2SO4+KCl+N2+H2O2 2HOCl+HSO3NH2→HSO3NCl2+2H2O
Inkcazo ngokubanzi	Iasidi ye-Sulfamic ibonakala njengento eqinileyo eyikristale emhlophe.Ubuninzi 2.1 g / cm3.Indawo yokunyibilika ngama-205°C.Ukutsha.Icaphukisa ulusu, amehlo kunye nenwebu.Ubuthi obuphantsi.Isetyenziselwa ukwenza idayi kunye nezinye iikhemikhali.Isetyenziswa njengento ekrwada ukulungiselela i-sweetener yokwenziwa oko kukuthi, i-sodium cyclohexylsulfamate.
Iintshukumo zoMoya naManzi	Ukunyibilika ngokuphakathi emanzini [Hawley].
Iprofayile yeReactivity	I-asidi ye-Sulfamic iphendula ngokugqithisileyo kunye neziseko.Izisombululo ezinamanzi zineasidi kwaye ziyagqwalisa.
Ingozi	Ityhefu ngokutya.
Ingozi yeMpilo	Ityhefu;Ukuphefumla, ukungenwa okanye ukudityaniswa kwesikhumba ngento kunokubangela ukwenzakala okumandundu okanye ukufa.Ukudibana nezinto ezinyibilikisiweyo kunokubangela ukutsha okumandla esikhumbeni nasemehlweni.Gwema naluphi na uqhagamshelwano lwesikhumba.Iziphumo zoqhagamshelwano okanye ukuphefumla zinokulibaziseka.Umlilo unokuvelisa iigesi ezicaphukisayo, ezidliwayo kunye/okanye ezinetyhefu.Amanzi aphuma kulawulo lomlilo okanye amanzi okungcungcuthekiswa anokuba ngumhlwa kunye/okanye abe netyhefu kwaye abangele ungcoliseko.
Ingozi yoMlilo	Into engatshiyo, yona ngokwayo ayitshi kodwa inokubola xa ifudunyezwa ikhuphe imisi edliwayo kunye/okanye enetyhefu.Ezinye zi-oxidizers kwaye zinokutshisa izinto ezinokutsha (umthi, iphepha, ioli, iimpahla, njl.).Ukudibana neentsimbi kunokuvela irhasi yehydrogen enokutsha.Izikhongozeli zinokugqabhuka xa zishushu.
Ukutsha kunye nokuSebenza	Ayinakutsha
Inkangeleko yoKhuseleko	Ityhefu ngendlela ye-intraperitoneal.Ityhefu ephakathi ngokuyiginya.Ulusu lomntu olucaphukisayo.I-corrosion ecaphukisa ulusu, amehlo kunye nenwebu.Into efudukela ekutyeni isuka kwimpahla yokupakisha.Iintshukumo ezinobundlobongela okanye eziqhumayo ngeklorini, i-nitrate yesinyithi + ubushushu, i-nitrites yesinyithi + ubushushu, ukuvutha kwe-HNO3.Xa ishushu ukuze ibole ikhupha imisi eyityhefu kakhulu ye-SOx kunye ne-NOx.Bona kwa SULFONATES.
Ithuba elikhoyo lokungakhuseleki	I-asidi ye-sulfamic isetyenziselwa ukucoca isinyithi kunye ne-ceramic, i-pulp ye-bleaching paper;kunye neempahla zentsimbi;ekucoceni iasidi;njenge-arhente yokuzinzisa i-chlorine kunye ne-hypochlorite kumachibi okubhukuda;iinqaba zokupholisa;kunye namaphepha okugaya.
Ukuhambisa ngenqanawe	I-UN2967 ye-Sulfamic acid, iklasi yengozi: 8;Iileyibhile: 8-Izinto eziNdlekayo.
Iindlela zokucoca	I-Crystallize NH2SO3H kumanzi kwi-70o (300mL nge-25g), emva kokucoca, ngokupholisa kancinane kwaye ulahle ibhetshi yokuqala yeekristale (malunga ne-2.5g) ngaphambi kokuma kumxube wetyuwa ye-ice for 20minutes.Iikristale zihluzwa ngokufunxa, zihlanjwe ngomthamo omncinci wamanzi abandayo e-ice, emva koko kabini nge-EtOH ebandayo kwaye ekugqibeleni nge-Et2O.Yomise emoyeni i-1hour, uze uyigcine kwi-desiccator phezu kwe-Mg (ClO4) 2 [Butler et al.Ind Eng Chem (Anal Ed) 10 690 1938].Ukulungiselela imathiriyeli esemgangathweni esisiseko bona iPure Appl Chem 25 459 1969.
Ukungahambelani	Isisombululo esinamanzi yi-asidi eyomeleleyo.Isabela ngobundlobongela kunye neeasidi ezomeleleyo (ingakumbi i-nitric acid evuthayo), iziseko, iklorini.Isabela ngokucothayo emanzini, yenze i-ammonium bisulfate.Ukungahambelani ne-ammonia, i-amines, i-isocyanates, i-alkylene oxides;epichlorohydrin, oxidizers.
