Acid Sulfamic. meatotino faaletino ma vailaau. talosaga

acid Sulfamic (isi igoa: aminosulfonic acid, acid, amidosulfuric, monoamide acid sulfuric) - o se mea o taʻega tioata rhombic colorless. O lotoa o Fua Faatatau: NH2SO2OH (po NH2SO3H).

meatotino faaletino o acids aminosulfonic:

1. O lenei lotoa o loo i ai i le tulaga o taʻega tioata colorless ia ua a foliga taimane. orthorhombic faiga Crystal: b = 0,8025 nm, o se = 0,8037 nm, z = 8, c = 0,9237 nm. I le tulaga o le zwitterion loo i ai i se tulaga crystalline.

2. acid Sulfamic ei ai le mamafa molecular nei: 97,098 amu O le manatu faaliusuavai e 205 tikeri, o le faalauteleina - 260 tikeri Celsius.

3. Solubility i acetone i le 25 o 0,04 tikeri; i le vai i le 20 tikeri 17,57, 22,77 i le 40 tikeri ma le 80 tikeri - 32,01; i ethyl le ava malosi i le 25 ° C 0,01; formamide i le 25 tikeri 0,18; i methanol i le 25 tikeri i le 0.4.

4. E i ai se density o 2,126 kalama i le santimetr³.

meatotino vailaau o acid sulfamic:

1. A vevela e 260 tikeri e decomposes e SO2 (teio ll oxide), SO3 (teio oxides lll), N2 (nitrogen) ma H 2 Le (le vai). O mea nei o lenei tali:

NH2SO2OH = SO2 (ll oxide Oser) + SO3 (teio oxides lll) + N2 (ua faamaloloina nitrogen o kasa) + H2O (le vai).

2. I le vevela o le potu, tele le hydrolyzed se mea. Ae i le vevela maualuga foi i ai ua hydrolyzed e NH4HSO4. Lē gata i lea, i se auala acidic le fua faatatau tali matua faateleina.

3. Faatasi ai ma le uʻamea eseese, carbonates, hydroxides ma oxides o ituaiga acid aminosulfonic NH2SO3M masima (igoa lautele - sulfamates) ma SOCl2 chloride thionyl - NH2SO2Cl sulfamoyl.

4. O le fegalegaleaiga ma HNO2 (acid nitrous) ua noatia i deamination oxidative - NH2SO3H + HNO2N2O + N2 (ua faamaloloina nitrogen o kasa) + H2SO4 (acid sulfuric). o loo faaaogaina lenei uiga faaalia e iloa ai le aofaiga o sulfuric monoamide acid ma pala le acid nitrous sili (HNO2) i le gaosia o dyes azo.

5. acid Sulfamic ua oxidised e chlorine (mata), bromine (br), permanganate potassium (KMnO4) ma chlorates e acid sulfuric (H2SO4) ma nitrogen (N2).

6. tali o lenei acid ma HClO (acid hypochlorous) po o NaClO (sodium hypochlorite) e taitai atu ai i le faavaega o N, N-dichloro- po o afua mai i isi N-chloro. O le tali i sodium (NA) i amonia suavai (NH3) e NaSO3NHNa, ma sulfate sodium (Na2SO4) e 6HSO3NH2 · 5Na2SO4 · 15N2O.

7. foi monoamide gaoioi le acid sulfuric ma alcohols muamua ma lona lua, ma phenols. Maualuluga, amines lona lua ma autu e fausia ai lenei aminosulfamaty acid ma amides o acids carboxylic - ammonium N-acyl sulfamates.

8. Ina ia faailoa o loo faaaogaina acid aminosulfonic le tali ma acid nitrous (HNO2) po o fusing ma benzoin (C14H12O3).

O le acid sulfuric faaaogaina monoamide

1. Alamanuia kemisi: faamamaina meafaigaluega pia ma maa susu mai teugatupe eseese minerale (ata tifaga oxide, masima maaa, tuufaatasi uʻamea). Tuuina atu o acid hydrochloric i le tulaga lenei e avea disadvantageous talu sulfamic itiiti corrosion.

2. I le fale ma i le mana o le pisinisi a le Malo: mo ona iloilo ipu umukuka ma le eria 'ai, o se vaega o nisi o vailaau.

3. O se mea e masani ona maua mo le sauniaina tuufaatasi nisi vailaau, e pei o herbicides ma le afi mea e tetee.

4. I electroplating: etching apa meaai ma e fatu electrolytes.

5. Ia aveese vavale mai lepa (latou vai faiga cooling).

6. Pe a faamamaina o masini mo le faia o pepa.

7. Ina ona iloilo sone o vaieli suauu.

E faapefea ona tausia acid sulfamic, ma mea e tatau ona faia puipuiga pe a faaaogaina i ai?

monoamide acid Sulfuric e faasino i se mea nonflammable. O le tele o aafiaga i luga o le tino ola e faatatau i le tuufaatasi o le vasega lona tolu o tulaga matautia. E mafua mu ogaoga e paʻu ma membranes mucous.

Teu lenei acid i taga polyethylene lua (tulaga fasefulu kilokalama) ua mamanuina faapitoa mo oloa vailaau. E taua le iloiloina e lelei soluble le oloa i H2O (le vai). Mo faaumiumi caking teuina.
