Kugwiritsa Ntchito Sulfamic Acid Ndi Kaphatikizidwe
| Chemical Properties | Sulfamic acid ndi white orthorhombic flaky crystal, yopanda fungo, yosasunthika komanso yopanda hygroscopic.Zosungunuka m'madzi ndi ammonia zamadzimadzi, zosungunuka pang'ono mu methanol, zosasungunuka mu ethanol ndi ether, komanso zosasungunuka mu carbon disulfide ndi madzi sulfure dioxide.Njira yake yamadzimadzi imakhala ndi asidi amphamvu kwambiri monga hydrochloric acid ndi sulfuric acid, koma kuwononga kwake kuzitsulo kumakhala kochepa kwambiri kuposa hydrochloric acid.Poizoniyo ndi yaying'ono kwambiri, koma sayenera kukhudzana ndi khungu kwa nthawi yayitali, ndipo sayenera kulowa m'maso. |
| Ntchito | Sulfamic acid imagwiritsidwa ntchito kwambiri mu electroplating, zochotsa madzi olimba, zotsekemera za acidic, chlorine stabilizers, sulfonating agents, denitrification agents, mankhwala ophera tizilombo toyambitsa matenda, zoletsa moto, mankhwala a herbicides, zotsekemera zopanga ndi zopangira. Sulfamic acid ndi kalambulabwalo wa mankhwala okoma okoma.Kuchita ndi cyclohexylamine kutsatiridwa ndi kuwonjezera kwa NaOH kumapereka C6H11NHSO3Na, sodium cyclamate. Sulfamic acid ndi asidi osungunuka m'madzi, amphamvu kwambiri.Pakati pa sulfuric acid ndi sulfamide, ikhoza kugwiritsidwa ntchito ngati kalambulabwalo wa mankhwala okoma okoma, chigawo cha mankhwala ochizira, mankhwala oyeretsa acidic, ndi chothandizira cha esterification. |
| Kugwiritsa ntchito | Sulfamic acid, monoamide wa sulfuric acid, ndi asidi amphamvu achilengedwe.Nthawi zambiri amagwiritsidwa ntchito poyeretsa mankhwala monga kuchotsa ma nitrites, carbonate- ndi phosphate-containing deposits. Sulfamic acid ingagwiritsidwe ntchito ngati chothandizira mu: Friedlander quinoline synthesis. Liquid Beckmann kukonzanso kwa kaphatikizidwe ka amides kuchokera ku ketoximes. Kukonzekera kwa α-aminophosphonates kudzera muzinthu zitatu zomwe zimachitika pakati pa aldehydes, amines, ndi diethyl phosphite. |
| Tanthauzo | ChEBI: Asidi wa sulfamic ndi wosavuta kwambiri wa sulfamic acid wopangidwa ndi atomu imodzi ya sulfure yomangidwa molumikizana ndi zomangira zamagulu a hydroxy ndi amino komanso zomangira ziwiri ku maatomu awiri a okosijeni.Ndi asidi amphamvu, omwe amapanga mchere wa sulphamate mosavuta, womwe umasungunuka kwambiri m'madzi ndipo umakhalapo ngati zwitterion H3N+.SO3-. |
| Zochita | Sulfamic acid ndi asidi amphamvu omwe amakhudzidwa ndi zinthu zambiri zoyambira.Amatenthedwa mpaka pamwamba pa malo osungunuka (209 ° C) pansi pa kupanikizika kwabwino kuti ayambe kuwola, ndipo akupitiriza kutenthedwa kufika pamwamba pa 260 ° C kuti awole kukhala sulfure trioxide, sulfure dioxide, nitrogen, haidrojeni ndi madzi. (1) Asidi wa sulfamic amatha kuchitapo kanthu ndi zitsulo kupanga mchere wowoneka bwino wa crystalline.Monga: 2H2NSO3H+Zn→Zn(SO3NH2)2+H2. (2) Angathe kuchita ndi oxides zitsulo, carbonates ndi hydroxides: FeO+2HSO3NH2→Fe(SO3NH2)2+H2O2 CaCO3+2HSO3NH2→Ca(SO3NH2)2+H2O+CO23 Ni(OH)2+2HSO3NH2→Ni(SO3NH2)2+H2O. (3) Atha kuchitapo kanthu ndi nitrate kapena nitrite: HNO3+HSO3NH2→H2SO4+N2O+H2O2 HNO2+HSO3NH2→H2SO4+N2+H2O. (4) Imatha kuchita ndi ma okosijeni (monga potaziyamu chlorate, hypochlorous acid, etc.): KClO3+2HSO3NH2→2H2SO4+KCl+N2+H2O2 2HOCl+HSO3NH2→HSO3NCl2+2H2O |
| Kufotokozera Kwambiri | Sulfamic acid imawoneka ngati yolimba ya crystalline yoyera.Kachulukidwe 2.1 g / cm3.Malo osungunuka 205 ° C.Zoyaka.Amasokoneza khungu, maso, ndi mucous nembanemba.Kawopsedwe wochepa.Amagwiritsidwa ntchito popanga utoto ndi mankhwala ena.Amagwiritsidwa ntchito ngati zopangira zopangira zotsekemera zopangira mwachitsanzo, sodium cyclohexylsulfamate. |
| Zotsatira za Air & Madzi | Zosungunuka bwino m'madzi [Hawley]. |
| Mbiri ya Reactivity | Sulfamic acid imakhudzidwa kwambiri ndi maziko.Madzi amadzimadzi amakhala acidic komanso akuwononga. |
| Zowopsa | Poizoni pomwetsa. |
| Ngozi Yaumoyo | POPHUNZITSA;pokoka mpweya, kumeza kapena kukhudzana ndi khungu kungayambitse kuvulala koopsa kapena kufa.Kukhudzana ndi zinthu zosungunula kungayambitse zilonda zowopsa pakhungu ndi maso.Pewani kukhudzana ndi khungu.Zotsatira zakukhudzana kapena kukokera mpweya zitha kuchedwa.Moto ukhoza kutulutsa mpweya wokwiyitsa, wowononga komanso/kapena wapoizoni.Kuthamanga kwa moto kapena madzi osungunula kungakhale kowononga komanso/kapena koopsa ndipo kumayambitsa kuipitsa. |
| Moto Wowopsa | Zinthu zosayaka, siziwotcha koma zimatha kuwola zikatenthedwa kuti zitulutse mpweya wowononga komanso/kapena wapoizoni.Zina ndi oxidizer ndipo zimatha kuyatsa zinthu zoyaka (matabwa, mapepala, mafuta, zovala, ndi zina).Kulumikizana ndi zitsulo kumatha kutulutsa mpweya woyaka wa haidrojeni.Zotengera zimatha kuphulika zikatenthedwa. |
| Kutentha ndi Kuphulika | Zosayaka |
| Mbiri Yachitetezo | Poizoni ndi intraperitoneal njira.Pang'ono poyizoni ndi kumeza.Khungu la munthu losautsa.Zowononga zowononga khungu, maso, ndi mucous nembanemba.Chinthu chomwe chimasamuka kupita ku chakudya kuchokera kuzinthu zoyikapo.Zochita zachiwawa kapena zophulika ndi klorini, zitsulo za nitrate + kutentha, nitrites zachitsulo + kutentha, kupsa mtima kwa HNO3.Ikatenthedwa kuti iwonongeke imatulutsa utsi woopsa kwambiri wa SOx ndi NOx.Onaninso SULFONATES. |
| Kukhudzika kuthekera | Sulfamic acid imagwiritsidwa ntchito poyeretsa zitsulo ndi ceramic, bleaching paper zamkati;ndi nsalu zitsulo;mu kuyeretsa asidi;monga stabilizing wothandizira klorini ndi hypochlorite m'madziwe osambira;nsanja zozizirirapo;ndi mapepala. |
| Manyamulidwe | UN2967 Sulfamic acid, Gulu la Zowopsa: 8;Zolemba: 8-Zinthu zowononga. |
| Njira Zoyeretsera | Crystallize NH2SO3H kuchokera m'madzi pa 70o (300mL pa 25g), mutatha kusefa, poziziritsa pang'ono ndikutaya gulu loyamba la makhiristo (pafupifupi 2.5g) musanayime mu osakaniza a ayezi-mchere kwa 20minutes.Makhiristo amasefedwa ndi kuyamwa, kutsukidwa ndi madzi oundana ochepa, kenako kawiri ndi EtOH yozizira ndipo pomaliza ndi Et2O.Yanikani mumlengalenga kwa 1hour, kenaka muyisunge mu desiccator pa Mg(ClO4)2 [Butler et al.Ind Eng Chem (Anal Ed) 10 690 1938].Pakukonza zinthu zoyambira zoyambira onani Pure Appl Chem 25 459 1969. |
| Zosagwirizana | Njira yamadzimadzi ndi asidi amphamvu.Amachita mwankhanza ndi zidulo zolimba (makamaka fuming nitric acid), maziko, klorini.Amachita pang'onopang'ono ndi madzi, kupanga ammonium bisulfate.Zosagwirizana ndi ammonia, amines, isocyanates, alkylene oxides;epichlorohydrin, oxidizers. |
