Asiti Sulfamic. 'Meleng le lik'hemik'hale thepa. kopo

asiti Sulfamic (mabitso a mang: aminosulfonic acid e, acid e, amidosulfuric, sulfuric acid e monoamide) - ntho hore e colorless rhombic kristale. Joalo komponeng ea Mokgwa wa ho Nahana: NH2SO2OH (kapa NH2SO3H).

thepa ya moaho wa acid aminosulfonic:

1. komponeng ena teng ka sebōpeho sa kristale colorless eo na le taemane sebopeho. Crystal oona tsamaisong orthorhombic: b, = 0,8025 NM, e = 0,8037 NM, med = 8,: c = 0,9237 NM. Ka mokgwa wa zwitterion e teng ka boemong ba ho bonaletsang.

2. Sulfamic acid e na le tsena tse latelang ho bekha a limolek'hule: 97,098 amu Ntlha qhibiliha ke likhato tse 205, katoloso ea - likhato 260 Celsius.

3. Solubility ka monohalogen acetone ka 25 ke likhato 0,04; ka metsi likhato 20 17.57, 22,77 likhato 40 le likhato 80 - 32,01; ka ethyl joala ho 25 ° C 0,01; formamide likhato 25 0.18; ka methanol likhato 25 ho 0,4.

4. Ho na le segokanyipalo sa tsa dikgerama 2,126 ka santimetr³.

Lik'hemik'hale thepa ea acid e sulfamic:

1. Ha likhato halefile ho 260 ho bola ho SO2 (sebabole oxide e ll,), SO3 (oxides sebabole lll), N2 (naetrojene) le H 2 O (metsi). Mona 's seo itsoara joang ka sena:

NH2SO2OH = SO2 (Oser oxide e ll,) + SO3 (oxides sebabole lll) + N2 (naetrojene e lokolloa ka khase) + H2O (metsi).

2. Ha wa kamore, ntho e haholo ha hydrolyzed. Empa ka thempereichara e phahameng haholo e hydrolyzed ho NH4HSO4. Ho feta moo, ka seaplane asiti tekanyo itsoara joang ka ea eketseha haholo.

3. Ka ho lirafshoa tse sa tšoaneng, carbonates, hydroxides le oxides mefuta aminosulfonic acid e NH2SO3M letsoai (karela lebitso - sulfamates) le thionyl chloride SOCl2 - NH2SO2Cl sulfamoyl.

4. sebelisana le HNO2 (acid e nitrous) e tlas'a deamination oxidative - NH2SO3H + HNO2N2O + N2 (naetrojene e lokolloa ka khase) + H2SO4 (acid e sulfuric). itsoara joang ka sena e sebediswa ho bona hore palo ea sulfuric acid e monoamide le ho bola ho feteletseng nitrous acid e (HNO2) ka tlhahisong ea lidae azo.

5. acid e Sulfamic e oxidised ke chloride (CL), bromine (BR), permanganate potassium (KMnO4) le chlorates ho acid e sulfuric (H2SO4) le ea naetrojene (N2).

6. itsoara joang ka ea acid e ena le HClO (acid e hypochlorous) kapa NaClO (sodium hypochlorite) isang sebopeho sa N, N-dichloro- kapa N-chloro sehlahisoa. Ba itšoara joang le sodium (Na) ka ammonia mokelikeli (NH3) ho NaSO3NHNa, ka sulfate sodium (Na2SO4) ho 6HSO3NH2 · 5Na2SO4 · 15N2O.

7. Hape monoamide acid e sulfuric a leka ho le alcohols mathomo le se mahareng, ka phenols. E phahameng, se mahareng le mathomo amines ho theha aminosulfamaty ena acid e le amides ea acid carboxylic - ammonium N-acyl sulfamates.

8. Ho khetholla acid e aminosulfonic e sebediswa ba itšoara joang ka acid e nitrous (HNO2) kapa fusing le benzoin (C14H12O3).

The acid e sebelisoa monoamide sulfuric

1. Industrial k'hemistri: hloekisa sethusathuto ea biri le lejoe lebese ho tloha mobung tse fapa-fapaneng matsoai (oxide e lifilimi, matsoai thatafala, metsoako tšepe). Tlhahiso ea asiti hydrochloric tabeng ena e ba disadvantageous kaha sulfamic tlase ts'enyeho.

2. Lapeng le ka matla a likhoebo tsa sechaba: ho sebetsana lisebelisoa kichineng le ho jela sebakeng seo, e le karolo ea ba bang sesepa.

3. Joalokaha ho lintho tse bonahalang e le e tala bakeng sa ho lokisetsa metsoako lik'hemik'hale tse itseng, tse kang dibolayangwang le mollo manganga thepa.

4. electroplating: mananose lijo thini le ho bopa electrolyte.

5. Ho tlosa mucus tloha matamo (bona metsi tsidifatso tsamaiso ea).

6. Ha hloekisa mechine ea ho etsa pampiri.

7. Ha sebetsana ka libaka tsa liliba oli.

Tsela ea ho bolokoe acid e sulfamic, 'me seo ba hlokolosi lokela ho nkoa ha e sebelisa neng?

Sulfuric acid e monoamide amana le ntho nonflammable. Tekanyo ea hore o susumetse ka ba phelang phelang amana metsoako ea sehlopha sa boraro a le kotsing. Ao bo a bakang chesa haholo ho letlalo le lera la mucous.

Boloka acid e sena habeli mokotla nhua polyethylene (bokgoni dikilogeramo mashome a mane) etselitsoeng ho toba bakeng sa lihlahisoa tsa lik'hemik'hale. Ke habohlokoa ho ho nahana ka hore sehlahiswa e hantle qhibilihang ka har'a ka H2O (metsi). Bakeng sa nako e telele polokelo caking.
