Fatty amines inoreva chikamu chakafara chemakemikari amine ane hurefu hwekabhoni kubva kuC8 kusvika kuC22. Kufanana nemaamine akajairika, anoiswa mumhando ina huru: mamines ekutanga, echipiri mamines, epamusoro amines, uye polyamines. Musiyano pakati pemaamine ekutanga, echipiri, uye epamusoro zvinoenderana nehuwandu hwemaatomu ehydrogen muammonia anotsiviwa nemapoka ealkyl.
Fatty amines ndeye organic derivatives yeammonia. Short-chain mafuta amines (C8-10) anoratidza kumwe kunyungudika mumvura, nepo refu-cheni mafuta amines kazhinji asinganyungudika mumvura uye anowanikwa sezvinwiwa kana zvimedu patembiricha yekamuri. Ivo vane zvakakosha zvivakwa uye, se organic base, vanogona kutsamwisa uye kukanganisa ganda uye mucous membranes.
Inonyanya kubudiswa kuburikidza nekuita kwemafuta ewaini ane dimethylamine kuti abudise monoalkyldimethyl tertiary amines, maitiro ezvinwiwa zvine mafuta ane monomethylamine kuumba dialkylmethyl tertiary amines, uye maitiro ezvinwiwa zvine mafuta ane ammonia kugadzira trialkyl tertiary amines.
Iyo nzira inotanga nekuita kwemafuta asidhi uye ammonia kugadzira mafuta nitriles, ayo anobva aiswa hydrogenated kuti abudise ekutanga kana yechipiri mafuta amines. Aya maamine ekutanga kana echipiri anopinda hydrogendimethylation kuti aumbe tertiary amines. Primary amines, mushure mecyanoethylation uye hydrogenation, inogona kushandurwa kuita diamines. Diamines inoenderera mberi necyanoethylation uye hydrogenation kugadzira triamines, iyo inogona kushandurwa kuita tetramines kuburikidza nekuwedzera cyanoethylation uye hydrogenation.
Zvishandiso zveFatty Amines
Primary amines inoshandiswa se corrosion inhibitors, lubricants, mold release agents, oiri additives, pigment processing additives, thickeners, wetting agents, fertilizer dust suppressants, engine oil additives, fetiraiza anti-caking agents, molding agents, flotation agents, gear lubricant, hydrophobic agents, wax and more additives.
Saturated high-carbon primary amines, senge octadecylamine, inoshanda senge mold release agents for hard rabha uye polyurethane foams. Dodecylamine inoshandiswa mukuvandudza machira echisikigo uye ekugadzira, seyakagadzika mumakemikari tin-plating mhinduro, uye mune inoderedza amination yeisomaltose kugadzira malt inobuda. Oleylamine inoshandiswa sedhiziri yekuwedzera mafuta.
Kugadzirwa kweCationic Surfactants
Maminisi ekutanga nemasaiti ayo anoshanda seanoshanda ore flotation agents, anti-caking agents emafetereza kana zvinoputika, mapepa ekudzivirira mvura, corrosion inhibitors, lubricant additives, biocides muindasitiri yepetroleum, zvinowedzerwa zvehuni nepeturu, emulsifiers, emulsifiers, uye mukugadzira organotives pigmental processing inowedzera. Iwo anoshandiswawo mukuchenesa mvura uye seanoumba maajenti. Maamine ekutanga anogona kushandiswa kugadzira quaternary ammonium salt-type asphalt emulsifiers, ayo anoshandiswa zvakanyanya mukuvaka nekugadzirisa migwagwa yegiredhi repamusoro, kuderedza kuwanda kwevashandi uye kuwedzera hupenyu hwekufamba.
Kugadzirwa kweNonionic Surfactants
Iwo adducts emafuta ekutanga amines ane ethylene oxide anonyanya kushandiswa se antistatic agents muindasitiri yemapurasitiki. Ethoxylated amines, isinganyunguriki mumapurasitiki, inotamira kumusoro, uko inotora hunyoro hwemhepo, ichipa iyo yepurasitiki pamusoro peantistatic.
Kugadzirwa kweAmphoteric Surfactants
Dodecylamine inopindirana nemethyl acrylate uye inopinda saponification uye neutralization kuti ibudise N-dodecyl-β-alanine. Aya ma surfactants anoratidzirwa nekupenya-ruvara kana kusava neruvara kwakajeka kwemvura mhinduro, kunyungudika kwakanyanya mumvura kana ethanol, biodegradability, kushivirira kwemvura yakaoma, kushatirwa kushoma kweganda, uye kuderera kwehuturu. Zvishandiso zvinosanganisira kupupa furo, emulsifiers, corrosion inhibitors, liquid detergents, shampoos, hair conditioners, softeners, uye antistatic agents.
