1 4-DIHIDROPIRIDĪNI JONU ŠĶIDRUMI HANČA ESTERIS UROTROPĪNS JONU ŠĶIDRUMU STRUKTŪRA Ķīmija

description

Maģistra darbā pētīta sakarība starp jonu šķidrumu struktūrām un Hanča estera sintēžu iznākumiem, tās veicot šajos jonu šķidrumos un lietojot urotropīnu kā reaģentu amonjaka un formaldehīda vietā. Sintezēti un raksturoti piecpadsmit šim pētījumam vajadzīgie jonu šķidrumi. Tie satur katjonus un anjonus ar mērķtiecīgi izmainītām struktūrām, lai varētu novērtēt šo jonu šķidrumu hidrofobo, ūdeņraža saišu donora-akceptora un elektrostatisko ietekmi uz pētīto Hanča estera sintēzes rezultātu. Šajā pētījumā ir salīdzināti alifātiskie un aromātiskie katjoni un anjoni, kā arī apspriesta jonu šķidrumu katalītiskā iedarbība salīdzinājumā ar to šķīdinātāja efektu. Darbā ir demonstrēta papildus katalizatora – glicīna labvēlīgā ietekme, kā arī izvēlēti paši labākie Hanča estera sintēzes reakcijas apstākļi.
