Umenzi Ixabiso Elihle Monoethanolamine CAS:141-43-5

Umenzi Ixabiso Elihle I-Monoethanolamine CAS: 141-43-5 Umfanekiso Obonakalayo

inkcazo emfutshane:

I-Monoethanolamine luhlobo lwe-amino alcohol ene-viscous hygroscopic equlethe amaqela eekhemikhali ze-amine kunye ne-alcohol. I-Monoethanolamine isasazeke kakhulu emzimbeni kwaye yinxalenye ye-lecithin. I-Monoethanolamine ineentlobo ezininzi zezicelo zoshishino. Umzekelo, i-Monoethanolamine ingasetyenziswa ekuveliseni iikhemikhali zezolimo kuquka i-ammonia kunye nokuveliswa kwamayeza kunye neesepha. I-Monoethanolamine ingasetyenziswa njenge-surfactant, i-reagent ye-fluorimetric kunye ne-arhente yokususa i-CO2 kunye ne-H2S. Kwicandelo lamayeza, i-ethanolamine isetyenziswa njenge-arhente ye-Vascular Sclerosing. I-Monoethanolamine ikwanayo nepropati ye-antihistaminic, enciphisa iimpawu ezimbi ezibangelwa kukubopha kwe-H1-receptor.

Inkcazo

Iimpawu zomzimba: I-Monoethanolamine kunye ne-triethanolamine zizinto eziqinileyo, ezingenambala, ezicacileyo, nezithambileyo kubushushu begumbi; i-diethanolamine yinto eqinileyo ekristale. Zonke ii-ethanolamines zifunxa amanzi kunye ne-carbon dioxide emoyeni kwaye zixutywa ngokungenasiphelo ngamanzi kunye nee-alcohols. Amanqaku okuqandisa azo zonke ii-ethanolamines anokuncitshiswa kakhulu ngokongezwa kwamanzi.
Ii-Ethanolamines zisetyenziswa kakhulu njengezinto ezisetyenziswa phakathi ekuvelisweni kwezinto ezisetyenziswa kwi-surfactants, eziye zabaluleka kakhulu kwezorhwebo njengee-sepa, iikhemikhali zelaphu nezesikhumba, kunye nee-emulsifiers. Ukusetyenziswa kwazo kuqala ekubholeni nasekusikeni iioyile ukuya kwiisepha zonyango kunye nezinto zokuhlamba ezikumgangatho ophezulu.

Ukusetyenziswa kweMonoethanolamine

1. I-Ethanolamine isetyenziswa njenge-arhente yokufunxa ukususa i-carbon dioxide kunye ne-hydrogen sulfide kwigesi yendalo nakwezinye iigesi, njenge-arhente yokuthambisa izikhumba, kunye ne-arhente yokusasaza iikhemikhali zezolimo. I-Ethanolamine ikwasetyenziswa kwii-polish, izisombululo zokushukuma kweenwele, ii-emulsifiers, kunye nokuhlanganiswa kwee-arhente ezisebenzayo kumphezulu (Beyer et al 1983; Mullins 1978; Windholz 1983). I-Ethanolamine ivumelekile kwizinto ezenzelwe ukusetyenziswa kwimveliso, ekucutshungulweni, okanye ekupakishweni kokutya (CFR 1981).
I-Ethanolamine ifumana iimpendulo eziphawulekayo kwi-amines eziphambili kunye nee-alcohols. Iimpendulo ezimbini ezibalulekileyo kwishishini ze-ethanolamine ziquka ukuphendula nge-carbon dioxide okanye i-hydrogen sulfide ukuze kuvele iityuwa ezinyibilikayo emanzini, kunye nokuphendula nge-long chain fatty acids ukwenza isepha ze-ethanolamine ezingathathi hlangothi (Mullins 1978). Iikhompawundi ze-ethanolamine ezithathelwe indawo, ezifana neesepha, zisetyenziswa kakhulu njengeemulsifiers, thickeners, wetting agents, kunye ne-detergents kwi-cosmetic formulations (kubandakanya izicoci zesikhumba, iikhrimu, kunye ne-lotions) (Beyer et al 1983).
2. I-Monoethanolamine isetyenziswa njenge-arhente yokusasaza iikhemikhali zezolimo, ekwenziweni kwezinto ezisebenzayo kumphezulu, njenge-arhente yokuthambisa izikhumba, nakwi-emulsifiers, iipolishi, kunye nezisombululo zeenwele.
3. Njengesixhobo esiphakathi seekhemikhali; i-corrosion inhibitor; kwimveliso yezinto zokuthambisa, iisepha, iipeyinti kunye neepolishi.
4. Isetyenziswa njenge-buffer; ukususwa kwe-carbon dioxide kunye ne-hydrogen sulfide kwimixube yegesi.
