Li-amine tse mafura li bolela sehlopha se pharaletseng sa metsoako ea amine ea organic e nang le bolelele ba ketane ea khabone ho tloha ho C8 ho ea ho C22. Joaloka li-amine tse akaretsang, li arotsoe ka mefuta e mene e meholo: li-amine tse ka sehloohong, li-amine tsa bobeli, li-amine tsa thuto e phahameng le li-polyamine. Phapang pakeng tsa li-amine tsa mantlha, tsa bobeli le tsa thuto e phahameng e ipapisitse le palo ea liathomo tsa hydrogen tse ammonia tse nkeloang sebaka ke lihlopha tsa alkyl.
Li-amine tse mafura ke lintho tse tsoang ho ammonia. Short-chain fatty amines (C8-10) e bonts'a ho qhibiliha ho itseng metsing, athe li-amine tse telele tsa mafura hangata ha li qhibilihe ka metsing 'me li teng e le maro kapa lintho tse tiileng mochesong oa kamore. Li na le thepa ea mantlha 'me, joalo ka metheo ea tlhaho, li ka halefisa le ho senya letlalo le lera la mucous.
Haholo-holo e hlahisoa ka karabelo ea lino tse tahang tse nang le dimethylamine ho hlahisa monoalkyldimethyl tertiary amines, karabelo ea lino tse mafura tse nang le monomethylamine ho theha dialkylmethyl tertiary amines, le karabelo ea lino tse mafura tse nang le ammonia ho hlahisa li-amine tse phahameng tsa liteko.
Ts'ebetso e qala ka karabelo ea li-acid tse mafura le ammonia ho hlahisa li-nitrile tse mafura, tseo ka nako eo li nang le hydrogenated ho hlahisa li-amine tsa mantlha kapa tsa bobeli tsa mafura. Li-amine tsena tsa mantlha kapa tsa bobeli li kena hydrogendimethylation ho etsa li-amine tsa thuto e phahameng. Li-amine tsa mantlha, ka mor'a cyanoethylation le hydrogenation, li ka fetoloa diamine. Li-diamine li tsoela pele ho etsa cyanoethylation le hydrogenation ho hlahisa triamine, e ka fetoloang ho ba tetramine ka ho eketsehileng cyanoethylation le hydrogenation.
Lisebelisoa tsa Fatty Amines
Li-amine tse ka sehloohong li sebelisoa e le li-corrosion inhibitors, lubricants, li-agents tsa hlobo, li-additives tsa oli, li-additives tsa pigment, li-thickeners, li-wetting agents, li-suppressants tsa lerōle la manyolo, li-additives tsa oli ea manyolo, li-anti-caking agents, li-molding agents, lisebelisoa tsa flotation, lubricant, lisebelisoa tsa hydrophobic, li-additives tse thibelang metsi.
Li-amine tsa mantlha tse nang le khabone e phahameng, joalo ka octadecylamine, li sebetsa joalo ka lisebelisoa tsa ho lokolla hlobo bakeng sa rabara e thata le foam ea polyurethane. Dodecylamine e sebelisoa ho nchafatsa liraba tsa tlhaho le tsa maiketsetso, joalo ka sehlahisoa sa motsoako oa lik'hemik'hale tsa tin-plating, le ho reductive amination ea isomaltose ho hlahisa lintho tse tsoang ho 'mela. Oleylamine e sebelisoa e le motsoako oa mafura a disele.
Tlhahiso ea li-Cationic Surfactants
Li-amine tsa mantlha le matsoai a tsona li sebetsa e le lisebelisoa tse sebetsang hantle tsa ho phaphamala ha ore, li-anti-caking agents bakeng sa manyolo kapa liqhomane, li-anti-caking agents bakeng sa manyolo kapa liqhomane, li-anti-caking agents tse thibelang metsi, li-corrosion inhibitors, li-additives tsa lubricant, li-biocides indastering ea peterole, li-additives bakeng sa libeso le peterole, lisebelisoa tsa ho hloekisa tsa elektroniki, li-emulsifiers, le tlhahisong ea li-organometal tsa organometal. Li boetse li sebelisoa ho hloekisa metsi le ho bōpa lintho. Li-amine tsa mantlha li ka sebelisoa ho hlahisa li-emulsifiers tsa mofuta oa letsoai oa quaternary ammonium salt-asphalt, tse sebelisoang haholo kahong le ho lokisoa ha litsela tsa boemo bo holimo, ho fokotsa matla a mosebetsi le ho lelefatsa nako ea bophelo ea litselana.
Tlhahiso ea Nonionic Surfactants
Li-adducts tsa li-amine tsa mantlha tse mafura tse nang le ethylene oxide li sebelisoa haholo-holo e le li-antistatic agents indastering ea polasetiki. Li-amine tse nang le ethoxylated, ha li sa qhibilihe ka har'a polasetiki, li fallela holimo, moo li monyang mongobo oa sepakapaka, e leng se etsang hore bokaholimo ba polasetiki bo be antistatic.
Tlhahiso ea li-Amphoteric Surfactants
Dodecylamine e sebetsana le methyl acrylate mme e feta saponification le neutralization ho hlahisa N-dodecyl-β-alanine. Li-surfactants tsena li khetholloa ka litharollo tsa tsona tsa metsi tse khanyang tse khanyang kapa tse se nang 'mala, ho qhibiliha ho hoholo metsing kapa ethanol, ho senyeha ha lintho, ho mamella metsi a thata, ho teneha ho fokolang ha letlalo, le chefo e tlaase. Lisebelisoa li kenyelletsa li-foaming agents, li-emulsifiers, corrosion inhibitors, li-detergents tsa metsi, li-shampoo, li-conditioner tsa moriri, li-softeners, le li-antistatic agents.
