Sulfamic acid. Anụ ahụ na chemical Njirimara. ngwa

Sulfamic acid (aha ndị ọzọ: aminosulfonic acid, acid, amidosulfuric, na igirigi ibu sulphuric acid monoamide) - a umi na bụ colorless rhombic kristal. Dị otú ahụ compound nke Formula: NH2SO2OH (ma ọ bụ NH2SO3H).

Physical Njirimara nke aminosulfonic asịd:

1. Nke a compound dị n'ụdị colorless kristal nke nwere a diamond udi. Crystal usoro orthorhombic: b = 0,8025 nm, a = 0,8037 nm, z = 8, c = 0,9237 nm. Na ụdị nke zwitterion dị a crystalline ala.

2. Sulfamic acid nwere ndị na-esonụ molekụla igwe: 97,098 amu The agbaze ekwu bụ 205 degrees, na mgbasa - 260 degrees Celsius.

3. Solubility na acetone na 25 bụ 0,04 degrees; na mmiri na 20 degrees 17,57, 22,77 na 40 degrees na 80 degrees - 32,01; na ethyl mmanya na 25 ° C 0,01; formamide na 25 degrees 0,18; na methanol na 25 degrees na 0.4.

4. Ọ nwere a njupụta nke 2,126 grams kwa santimetr³.

Chemical Njirimara nke sulfamic acid:

1. Mgbe kpụ ọkụ n'ọnụ na 260 degrees ya erekasịchaala ka SO2 (sọlfọ oxide LL), SO3 (sọlfọ oxides lll), N2 (nitrogen) na H 2 O (mmiri). Ebe a bụ ihe a mmeghachi omume:

NH2SO2OH = SO2 (Oser oxide LL) + SO3 (sọlfọ oxides lll) + N2 (nitrogen a tọhapụrụ ka gas) + H2O (mmiri).

2. Mgbe ụlọ okpomọkụ, a umi n'ụzọ bụghị hydrolyzed. Ma na kwa elu okpomọkụ ya na-hydrolyzed ka NH4HSO4. Ọzọkwa, ihe acidic ajụ mmeghachi omume ọnụego na-abawanye budata.

3. dị iche iche ọla, carbonates, hydroxides na oxides nke aminosulfonic acid forms NH2SO3M nnu (ọnyà aha - sulfamates) na thionyl chloride SOCl2 - NH2SO2Cl sulfamoyl.

4. The mmekọrịta HNO2 (nitrous acid) na-doro oxidative deamination - NH2SO3H + HNO2N2O + N2 (nitrogen a tọhapụrụ ka gas) + H2SO4 (na igirigi ibu sulphuric acid). Mmeghari a na-eji na-ekpebi ego nke na igirigi ibu sulphuric acid monoamide na-amalite irekasị ngafe nitrous acid (HNO2) ke imewe nke azo dyes.

5. Sulfamic acid na-oxidised site chlorine (cl), bromine (br), potassium permanganate (KMnO4) na chlorates na igirigi ibu sulphuric acid (H2SO4) na nitrogen (N2).

6. Mmeghachi omume nke a acid na HClO (hypochlorous acid) ma ọ bụ NaClO (sodium hypochlorite) eduga ná guzobe nke N, N-dichloro- ma ọ bụ N-chloro emepụta. The mmeghachi omume na sodium (Na) na mmiri mmiri amonia (NH3) na NaSO3NHNa, na sodium sulfate (Na2SO4) na 6HSO3NH2 · 5Na2SO4 · 15N2O.

7. Ọzọkwa monoamide na igirigi ibu sulphuric acid mkpatụ na isi na sekọndrị alcohols, na phenols. Tertiary, sekọndrị na isi amines na-etolite a acid aminosulfamaty na amides nke carboxylic asịd - ammonium N-acyl sulfamates.

8. Iji mata aminosulfonic acid a na-eji mmeghachi omume na nitrous acid (HNO2) ma ọ bụ fusing na benzoin (C14H12O3).

The ojiji monoamide na igirigi ibu sulphuric acid

1. Industrial Chemistry: nhicha ngwa biya na mmiri ara ehi nkume dị iche iche ịnweta ego (oxide fim, ekweghị ekwe salts, ígwè ogige). Production nke hydrochloric acid na nke a na-aghọ disadvantageous kemgbe sulfamic obere corrosion.

2. N'ụlọ na na ike nke ọha na eze ụlọ ọrụ: maka nhazi kichin arịa na iri ebe, dị ka akụkụ nke ụfọdụ omo.

3. Dị ka a akụrụngwa n'ihi akwadebe ụfọdụ chemical ogige, dị ka ogwu ndi na ọkụ na-eguzogide ọgwụ ihe.

4. electroplating: etching tin nri na ike electrolytes.

5. Iji wepu imi si ọdọ mmiri (ha mmiri jụrụ usoro).

6. Mgbe nhicha ígwè na-eme ka akwụkwọ.

7. Mgbe nhazi zones mmanụ akọwa.

Olee otú a ga-edebe sulfamic acid, na ihe-elezi anya na kwesịrị iwere mgbe eji ya?

Na igirigi ibu sulphuric acid monoamide akọ a nonflammable umi. Ogo mmetụta na ndụ organism akọ ogige nke klas nke atọ nke ihe ize ndụ. Ọ na-akpata oké Burns na akpụkpọ mucous membranes.

Echekwa a acid na abụọ polyethylene akpa (ikike iri anọ kilogram) e kpọmkwem maka chemical ngwaahịa. Ọ bụ uru na-ewere na ngwaahịa bụ ọma soluble na H2O (mmiri). N'ihi na ruo ogologo oge nchekwa caking.
