Iimveliso
Diethyl monoisopropanolamine
Intshayelelo
I-Diethyl alcohol monoisopropanolamine luhlobo lwezinto eziphilayo, ifomula yemichiza ye-C7H17O3N, engenambala okanye ekhanyayo etyheli ecacileyo kunye ne-ammonia incasa ivuselela ulwelo olubonakalayo, oluzinzileyo kwiqondo lokushisa kunye noxinzelelo.I-Diethyl yotywala i-monoisopropanolamine luhlobo olutsha lwezinto eziluhlaza zokuncedisa, ezinomphumela ocacileyo wokusila, kwaye isetyenziswa ngokubanzi kwi-samente yokusila.
(1) I-Diethanolamine monoisopropyl olamine isetyenziswa kakhulu kwi-surfactants, isetyenziswa ngokubanzi kwimichiza ekrwada, i-pigments, iyeza, izinto zokwakha kunye nezinye iindawo, kwizongezo zesamente, iimveliso zokunakekelwa kwesikhumba kunye ne-textile softener izicelo ezininzi.
(2) Okwangoku, kwintsimi ye-samente yokusila i-AIDS, ininzi yezinto ezixutywayo ziyimveliso eyodwa okanye edibeneyo yotywala, i-alcohol amine, i-acetate kunye nezinye izinto ezisetyenziswayo zeekhemikhali.Xa kuthelekiswa nezinye izongezo zesamente ezifanayo, i-diethyl alcohol monoisopropyl alcohol amine (DEIPA) ineenzuzo ezinkulu ekuphuculeni ukusebenza kakuhle kokusila, ukonga amandla kunye nokunciphisa ukusetyenziswa kunye nokuphucula amandla e-samente.
Indlela yokuvelisa
I-1.I-synthesis ye-monoisopropanolamine (DEIPA) ineendlela ezintathu eziphambili: okokuqala, i-reaction synthesis ye-ammonia kunye ne-ethylene oxide (EO) kunye ne-propylene oxide (PO);
Okwesibini, yenziwe ngokusabela kwe-MIPA kunye ne-EO.Okwesithathu, yenziwe kwi-diethanolamine (DEA) kunye ne-PO.
2.I-ammonia kunye ne-epoxy olefin indlela yokusabela
Le ndlela yimpendulo yothotho lwamanqanaba amathathu.I-ammonia iphendula kunye ne-EO ukuvelisa i-ethanolamine, i-diethanolamine kunye ne-triethanolamine.Ii-reactants zenziwe nge-PO, kwaye iimveliso ezijoliswe kuzo zifunyenwe emva kokucocwa.Okanye, i-ammonia iphendula kunye ne-PO ukuvelisa i-monoisopropanolamine, i-diisopropanolamine kunye ne-triisopropanolamine, kwaye i-reactant yenziwe nge-EO, kwaye imveliso ekujoliswe kuyo ifunyenwe emva kokuhlanjululwa.
3.DEA indlela
Le ndlela isebenzisa i-DEA kunye ne-PO reaction ukuvelisa into ekujoliswe kuyo i-DEIPA.Inzuzo yale ndlela kukuba izinga lokuphendula likhawuleza, ukhetho lokuphendula luphezulu, kwaye ukunikezelwa kwezinto eziluhlaza kwanele kwaye kuzinzile.Imveliso yethu ye-DEIPA, okwangoku, yonke isebenzisa le ndlela, kodwa kukho umahluko kwisityalo sokuvelisa okanye ukusabela kombhobho, kwi-isomer yemveliso kunye nokuzinza komgangatho.
