DI-N-PROPYL OXALATE synthesis
- Product Name:DI-N-PROPYL OXALATE
- CAS Number:615-98-5
- Molecular formula:C8H14O4
- Molecular Weight:174.19
Yield:615-98-5 85%
Reaction Conditions:
at 150; for 48 h;
Steps:
11 Example 11
15 g of [ChCl] 2 [CoCl2.6H2O] eutectic solvent and 18.00 g(0.20 mol) of oxalic acid were mixed with 60.07 g(1.00 mol)Propanol into the reaction flask,Stirring,The control temperature was 150 ° C,Reaction for 48 hours,Take 1 μL sample into the sample,The yield of dipropyl oxalate in the reactants wasdetermined by gas chromatography,The column was HP5MS.The specific test conditions are: chamber temperature 140 ,Gasification chamber 320 ° C,Detection chamber 320 .The reaction selectivity was determined by a FinniganTraceDSQ GC-MS,The column used was HP5MS.The conversion of dipropyl oxalate underthe above reaction conditions was 85%Selectivity is 100%.The reaction solution was allowed to stand,The upper organic phase obtained by the separation was theesterification reaction product of dipropyl oxalate.The low-temperature eutectic solvent of the lower layer canbe reused after simple water removal.
