Sulfamic acid. Guryaha jirka iyo kiimikada. Codsiga

acid Sulfamic (magacyada kale: aminosulfonic acid, acid, amidosulfuric, monoamide acid sulfuric) - walax waa kiristaalo rhombic Biyuhu. Caanoboorka noocan ah waa: NH2SO2OH (ama NH2SO3H).

guryaha jirka ah ee acids aminosulfonic:

1. Maaddadani waxay ku dhex jirtaa qaabka korrinka aan lahayn, oo leh qaab diirran. Meeluhu waa orthorhombic: b = 0.8025 nm, a = 0.8037 nm, z = 8, c = 0.9237 nm. In qaab jwiterion ah, waxay u jirtaa xaalad kristaan ah.

2. Sulfamic acid waxay leedahay miisaannada soo socda: 97,098 subaxnimo. Xaaladda dhibicku waa 205 digrii, qallajinta waa 260 degrees Celsius.

3. Solubitir ee acetone at 25 darajo waa 0.04; Biyaha ku jira 20 digrii 17,57, oo ah 40 digrii 22,77 iyo 80 darajo - 32,01; In dietyl alcohol ah 25 ° C, 0.01; Qaab dhismeedka 25 digrii 0.18; Methanoolka 25 digrii 0.4.

4. Waxay leedahay cufnaanta 2.126 garaamkiiba halkii mitir.

Noocyada kiimikada ee sulfamic acid:

1. Marka uu kululeeyo 260 digrii, waxay u jajabisaa SO2 (sulfur oxide ll), SO3 (sulfur oxide lll), N2 (nitrogen) iyo H2O (biyaha). Tani waa sida dareen-celintu u egtahay:

NH2SO2OH = SO2 (oxides oxide ll) + SO3 (sulfur oxide lll) + N2 (nitrogen, oo loo sii daayo gaas) + H2O (biyo).

2. Heerkulka qolka, walaxdaas si aan toos ahayn looma dhejinaynin qalabka korontada. Laakiin heerkul aad u sarreeya waxaa lagu qalajiyaa NH4HSO4. Waxaa intaa dheer, in dhexdhexaad ah acidic heerka falcelinta u kordho.

3. Dhuxulo kala duwan, carbonates, hydroxides iyo oxides, aminosulfonic acid waxay sameeyaan NH2SO3M (oo loo yaqaanno sulfamate), oo leh chloride chloride SOCl2-NH2SO2Cl sulfamoyl chloride.

4. In lala of HNO2 (nitrus acid) Oo Qaliin deamination murqo - NH2SO3H + HNO2N2O + N2 (nitrogen waxaa la sii daayay sida gaaska) + H2SO4 (sulfuric acid). Dareenkan waxaa loo isticmaalaa si loo go'aamiyo qadarka sulfuric acid monoamide iyo qallajinta sicir bararka xad-dhaafka ah (HNO2) ee soo saarida wax yar.

5. Sulfamic acid waa oksitized by chlorine (Cl), bromine (Br), kareemka kalluunka (KMnO4) iyo chlorates si sulfuric acid (H2SO4) iyo nitrogen (N2).

6. Reaction of acid la HClO (hypochlorous acid) ama NaClO (sodium haybokollorayt) keenaysaa in formation of N, N-dichloro- ama N-chloro derivative. falcelinta la sodium (Na) ee ammonia dareere ah (NH3) si NaSO3NHNa, la sodium sulfate (Na2SO4) si 6HSO3NH2 · 5Na2SO4 · 15N2O.

7. Sidoo kale monoamide sulfuric acid wuxuu ka soo horjeedaa alkolada asaasiga ah iyo labaad, oo leh astaamo. Qalabyada kala duwan ee caadiga ah, asaasiga ah iyo kuwa hoose ee aasaasiga ah ee leh aminosulfamates acid, iyo amides oo ah carboksilic-ammonium acids N-acyl sulfamates.

8. Si loogu aqoonsado astaamaha aminosulfonic, jawaab celin ah Nitrous acid (HNO2) ama fusion leh benzoin (C14H12O3) ayaa loo isticmaalaa.

Isticmaalida monoamide sulfuric acid

1. Kalasooca kiimikada: Nadiifinta qalabka laga helo biirka iyo dhagaxa caanaha, laga bilaabo kaydka macdanta kala duwan (filimka oksida, cusbooyinka adkaha ah, xeryaha birta). Production Aashito in ay taasi dhacdo, waxa weeye khasaari, sida sulfamic yar daxalka.

2. Nolol maalmeedka iyo shirkadaha dadwaynaha ee dadwaynaha: sida loo isticmaalo qalabka jikada iyo alaabada cuntada, iyada oo qayb ka ah shayada daawooyinka qaarkood.

3. Waxyaabo cayriin ah oo loogu talagalay diyaarinta kiimikooyinka kiimikada qaarkood, tusaale ahaan, herbicides iyo alaabta gubanaysa.

4. Xeeldheeraha: adoo cunaya cunto iyo abuurista elektirito.

5. Si aad uga qaaddo xabo dabaasha ah (nidaamyada biyaha qaboojinta).

6. Marka la nadiifinayo mashiinnada loogu talagalay inay abuuraan warqad

7. Marka la shaqeynayo aagga saliidda.

Sidee bay udub dhexaad u tahay sulfamic acid, iyo waa maxay tallaabooyinka taxadirka ah in la qaato marka la isticmaalayo?

Monoamide ee sulfuric acid waxaa lagu sifeeyay walax walax leh. Marka loo eego xaddiga soo-noolaanshaha noolaha nool, waxa loola jeedaa xeryaha halista ah halista halista ah. Wuxuu keenaa gubasho daran maqaarka iyo xuubka xuubka.

Aashitadan waxaa lagu keydiyaa bacaha polyetylen ee laba kiiloomitir ah (kiilo kiilo kiilogaraam), loogu talagalay gaar ahaan alaabada kiimikada. Waxaa haboon in la tixgeliyo in badeecadu ay si fudud u foorarsan tahay H2O (biyo). Iyada oo la xajisto kaydinta dheeraadka ah.
