Xyaum tsis muaj kev lag luam tuaj yeem ua yam tsis muaj tshuaj lom neeg. Cov khoom siv ntxiv yog siv rau hauv kev ua liaj ua teb, kev lag luam khoom noj, thaum hnav khaub ncaws tawv, hauv kev tsim kho thiab hauv ntau qhov chaw ntawm tib neeg kev ua haujlwm. Ntawm tag nrho cov ntawm lawv, ib qho chaw tshwj xeeb yog nyob ntawm ammonium carbon ntsev, uas yog universal.

Carbon ammonium ntsev

Carbon ammonium ntsev - ib qho dawb inorganic compound, soluble hauv dej, yog cov khoom lag luam ntawm kev sib cuam tshuam ntawm carbonic acid thiab ammonium ntsev.

Crystals ntawm cov teeb meem nyob rau hauv qhib huab cua sai sai decompose nrog tso tawm ntau ntawm ammonia thiab carbon dioxide, thiab ces volatilize. Muaj ob hom tshuaj compound:

1. Carbon-ammonium ntsev ntawm hom B, uas nquag siv hauv kev lag luam metallurgical, thaum lub sijhawm tsim cov uranium ore, rau cov txheej txheem flotation, neutralization ntawm chrome tawv thiab xim ntawm cov khoom.
2. Ntshav qib A, uassiv rau kev tsim khoom ntawm cov khoom organic, kev sib txuas ntawm cov tshuaj reagents.

Txhua yam tshuaj lom neeg tsis yaj hauv ethanol thiab acetone. Cov tshuaj tau txais los ntawm kev pib redox cov tshuaj tiv thaiv ntawm ammonium ntsev thiab carbonic acid.

tshuaj muaj pes tsawg leeg

Raws li lub xeev cov qauv, carbon ammonium ntsev yuav tsum muaj, hais txog cov teeb meem qhuav, tsawg kawg 99% ammonium bicarbonate, ammonium carbonate - tsis ntau tshaj 1% thiab dej khi ntawm qib molecular tsis ntau tshaj 3%.

Cov tshuaj muaj pes tsawg leeg tuaj yeem sib txawv nyob ntawm kev siv cov tshuaj crystalline. Yog li, rau kev lag luam zaub mov, qhov muaj pes tsawg leeg yuav tsum muaj tsawg kawg yog 20.9% NH _{3. Qhov loj feem ntawm lwm cov tebchaw muaj kev tswj hwm nruj thiab yuav tsum tsis txhob tshaj cov ntsuas hauv qab no:}

• hnyav hlau - 510 -4;
• arsenic – 110-4;
• hlau thiab nws cov valence compounds - 110 -3;
• chlorine thiab chlorides - 110 -3;
• dej-insoluble compounds – 510-3.

Cov ntsuas no yog txhais los ntawm TU U 6-04687873.025-95, chemical formula - NH₄HCO_3.

Lub cev thiab tshuaj tsis haum

Carbon-ammonium ntsev muaj cov ntsuas uas txhais tau tias lawv yog cov khoom tshwj xeeb:

• lub xim ntawm cov muaju ntawm cov khoom tuaj yeem sawv cev los ntawm cov xim dawb, liab lossis grey tint;
• ntau feem ntawm ammonia raupawg A yuav tsum sib haum rau 21%, rau hom B - 20.7%;
• mass residue tom qab calcination yuav tsum tsis pub tshaj 0.008% rau hom A, thiab tsis ntau tshaj 0.02 rau hom B.

Tsuas yog cov khoom uas ua tau raws li cov kev ntsuas no tuaj yeem txhais tau tias yog carbon ammonium ntsev. GOST 9325-79 consolidates cov kev cai no, thiab kuj tswj cov kev cai rau ntau lawm, tsheb thauj mus los thiab cia, ceev faj thiab kev nyab xeeb.

Scope of application

Carbon ammonium ntsev yog siv dav hauv kev lag luam zaub mov thiab kev ua liaj ua teb. Nyob rau hauv thawj cheeb tsam, nws yog siv nyob rau hauv lub guise ntawm additive E503, feem ntau hloov khoom noj khoom haus poov xab thiab zaub mov ammonium carbonate. Rau kev siv, cov khoom yog yaj hauv dej ntawm qhov kub ntawm 20 o C thiab siab dua, thiab tom qab ntawd ntxiv rau hauv daim ntawv qhia sib tov sai ua ntej cov hmoov nplej tawm.

Lub cev thiab tshuaj tsis haum ntawm carbon ammonium ntsev tso cai rau nws siv los ua chiv. Los ntawm kev qhia cov khoom siv lead ua, lawv ua tiav qeeb lossis ua tiav ntawm cov txheej txheem ntawm kev sib sau ntawm nitrites hauv cov av, uas muaj txiaj ntsig zoo rau cov ripening thiab kom muaj nuj nqis ntawm cov qoob loo:

1. Yield nce 15-45%.
2. Thawj theem ntawm cov qoob loo txiv hmab txiv ntoo tuaj ua ntej ib mus rau ob lub lis piam.
3. Txo cov av xav tau phosphate chiv.
4. Txhawb kev tsim ntawm humus.

Nyob hauv peb lub teb chaws, kev tsim cov chiv raws li carbon ammonium ntsev yog tsom rau cov neeg ua lag luam hauv tsev, vim li cas cov khoom lag luam yog ntau npaum li cas?qis dua tus nqi ntawm cov analogues txawv teb chaws.

Kev Tiv Thaiv

Carbon-ammonium ntsev yog nyob rau qib 4th txaus ntshai. Lawv muaj ob yam khoom uas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv - ammonia thiab carbon dioxide. Thawj lub ntsiab lus yog tshuaj lom heev, ua rau khaus yog tias nws nkag mus rau hauv lub ntsws. Nyob rau hauv rooj plaub ntawm kev lom, lub hauv paus paj hlwb raug cuam tshuam, mob taub hau, lacrimation, convulsions thiab lwm yam tsos mob tshwm sim.

Cov pa roj carbon dioxide muaj cov nyhuv narcotic thiab sedative. Hauv qhov ntau, nws ua rau qhov chaw ua pa tsis muaj zog, ua rau ua pa nyuaj thiab tuaj yeem ua rau tuag vim tsis muaj oxygen.

Yog li ntawd, cov ntsev carbon ammonium tsuas yog siv tau rau hauv cov khaub ncaws tshwj xeeb, tsom iav, hnab looj tes tiv thaiv alkali, thiab lub ntsej muag roj. Tom qab ua haujlwm, ua raws li cov cai ntawm kev nyiam huv ntawm tus kheej, da dej sov yog qhov zoo tshaj plaws.
