| dc.description.abstract | Darbā pētīta 1,4–dioksāna iegūšana skābos jonu šķidrumos ciklodehidratācijas reakcijās no etilēnglikola un dietilēnglikola. 1,4-Dioksāns iegūts mainot reakcijas apstākļus un izmantoto reaģentu molārās attiecības. Darbā jonu šķidrumos veikta arī tetrahidrofurāna iegūšana no 1,4-butāndiola. Spirtu dehidratācijas reakcijās iegūto produktu tīrība noteikta ar GH/MS, kā arī ar Karla Fišera titrēšanas metodi noteikts ūdens daudzums produktā. Sintezēto Bonsteda skābo jonu šķidrumu tīrība noteikta ar AEŠH/MS . | en_US |
| dc.description.abstract | Synthesis of 1,4-dioxane in cyclodehydration reaction from ethylene glycol and diethylene glycol using ionic liquids as catalysts, has been carried. 1,4-Dioxane was prepared by changing reaction conditions and molar ratios of used reagents. Synthesis of tetrahydrofuran from 1,4-butanediol has also been investigated. The purity of obtained alcohol dehydration products was determined by GC/MS and content of water in product was measured with Karl Fischer titration. The purity of synthesised Bronsted acidic ionic liquids was identified by HPLC/MS. | en_US |
