Diethyl monoisopropanolamine
Selelekela
Diethyl joala monoisopropanolamine ke mofuta oa lintho tse phelang, foromo ya lik'hemik'hale C7H17O3N, colorless kapa leseli mosehla bonaletsang le ammonia tatso susumetsoa viscous mokelikeli, tsitsitseng mocheso kamoreng le khatello.Diethyl alcohol monoisopropanolamine ke mofuta o mocha oa thepa ea thuso ea ho sila e tala, e nang le phello e hlakileng ea ho sila, 'me e sebelisoa haholo ho thusa ho sila samente.
(1) Diethanolamine monoisopropyl olamine e sebelisoa haholo-holo ho li-surfactants, tse sebelisoang haholo linthong tse tala tsa lik'hemik'hale, li-pigments, meriana, thepa ea mohaho le masimo a mang, ka li-additives tsa samente, lihlahisoa tsa tlhokomelo ea letlalo le lisebelisoa tsa textile softener.
(2) Hona joale, tšimong ea AIDS e silang samente, boholo ba metsoako ke lihlahisoa tse le 'ngoe kapa tse kopantsoeng tsa joala, amine ea joala, acetate le lisebelisoa tse ling tsa lik'hemik'hale.Ha ho bapisoa le li-additives tse ling tse tšoanang tsa samente, diethyl alcohol monoisopropyl alcohol amine (DEIPA) e na le melemo e meholo ho ntlafatsa ts'ebetso ea ho sila, ho boloka matla le ho fokotsa tšebeliso ea matla le ho ntlafatsa matla a samente.
Mokhoa oa Tlhahiso
1.The synthesis ea monoisopropanolamine (DEIPA) e na le litsela tse tharo tse ka sehloohong: pele, ho itšoara ha ammonia ka ethylene oxide (EO) le propylene oxide (PO);
Ea bobeli, e thehoa ke karabelo ea MIPA le EO.Ea boraro, e entsoe ho tloha diethanolamine (DEA) le PO.
2.Amonia le tsela ea epoxy olefin reaction
Tsela ena ke ea mekhahlelo e meraro.Ammonia e sebetsana le EO ho hlahisa ethanolamine, diethanolamine le triethanolamine.Li-reactants li entsoe ka PO, 'me lihlahisoa tse lebisitsoeng li fumanoa ka mor'a tlhoekiso.Kapa, ammonia e sebetsana le PO ho hlahisa monoisopropanolamine, diisopropanolamine le triisopropanolamine, 'me reactant e entsoe ka EO,' me sehlahisoa se lebisitsoeng se fumanoa ka mor'a tlhoekiso.
3.DEA tsela
Tsela ena e sebelisa karabelo ea DEA le PO ho hlahisa ntho e lebeletsoeng ea DEIPA.Molemo oa tsela ena ke hore sekhahla sa karabelo se potlakile, khetho ea karabelo e phahame, 'me phepelo ea lihlahisoa tse tala e lekane ebile e tsitsitse.Tlhahiso ea rona ea DEIPA, hajoale, kaofela e sebelisa tsela ena, empa ho na le phapang ho semela sa tlhahiso kapa karabelo ea liphaephe, ho isomero ea sehlahisoa le botsitso ba boleng.
