Imikhiqizo
I-Diethyl monoisopropanolamine
Isingeniso
I-Diethyl alcohol monoisopropanolamine iwuhlobo lwento ephilayo, ifomula yamakhemikhali engu-C7H17O3N, engenambala noma ephuzi ekhanyayo ebonisa ngale ne-ammonia flavour evuselela uketshezi olubonakalayo, oluzinzile ekamelweni lokushisa nokucindezela.I-Diethyl alcohol monoisopropanolamine iwuhlobo olusha lwezinto zosizo zokugaya eziluhlaza, ezinomphumela osobala wokusiza wokugaya, futhi isetshenziswa kakhulu ekusizeni usimende.
(1) I-Diethanolamine monoisopropyl olamine isetshenziswa kakhulu kuma-surfactants, asetshenziswa kakhulu ezintweni ezingavuthiwe zamakhemikhali, i-pigment, imithi, izinto zokwakha kanye neminye imikhakha, ezithasiselweni zikasimende, imikhiqizo yokunakekelwa kwesikhumba kanye ne-textile softener izicelo eziningi.
(2) Njengamanje, emkhakheni we-AIDS wokugaya usimende, ukwakheka okuningi kuyimikhiqizo eyodwa noma eyinhlanganisela yotshwala, i-alcohol amine, i-acetate nezinye izinto zokusetshenziswa zamakhemikhali.Uma kuqhathaniswa nezinye izithasiselo zikasimende ezifanayo, i-diethyl alcohol monoisopropyl alcohol amine (DEIPA) inezinzuzo ezinkulu ekuthuthukiseni ukusebenza kahle kokugaya, ukonga amandla kanye nokunciphisa ukusetshenziswa kanye nokwenza ngcono amandla usimende.
Indlela Yokukhiqiza
I-1.I-synthesis ye-monoisopropanolamine (DEIPA) inemizila emithathu eyinhloko: okokuqala, ukusabela kwe-ammonia nge-ethylene oxide (EO) ne-propylene oxide (PO);
Okwesibili, kwakhiwa ukusabela kwe-MIPA ne-EO.Okwesithathu, ihlanganiswa kusuka ku-diethanolamine (DEA) ne-PO.
2.I-ammonia ne-epoxy olefin yokusabela umzila
Lo mzila ukusabela kochungechunge lwezigaba ezintathu.I-ammonia isabela ne-EO ukuze ikhiqize i-ethanolamine, i-diethanolamine ne-triethanolamine.Ama-reactants ahlanganiswa ne-PO, futhi imikhiqizo eqondiwe itholakala ngemva kokuhlanzwa.Noma, i-ammonia isabela ne-PO ukukhiqiza i-monoisopropanolamine, i-disopropanolamine ne-triisopropanolamine, futhi i-reactant ihlanganiswa ne-EO, futhi umkhiqizo ohlosiwe utholakala ngemva kokuhlanza.
3.DEA umzila
Lo mzila usebenzisa ukusabela kwe-DEA kanye ne-PO ukukhiqiza into eqondiwe i-DEIPA.Inzuzo yalo mzila ukuthi izinga lokusabela liyashesha, ukukhetha kokusabela kuphezulu, futhi ukunikezwa kwezinto zokusetshenziswa kwanele futhi kuzinzile.Ukukhiqizwa kwethu kwe-DEIPA, okwamanje, konke kusebenzisa lo mzila, kodwa kunomehluko endaweni yokukhiqiza noma ukusabela kwepayipi, ku-isomer yomkhiqizo nokuzinza kwekhwalithi.
