- Molecular formula:C9H18O2
- Molecular Weight:158.24
Yield:23361-78-6 93%
Reaction Conditions:
at 80; for 12 h;
Steps:
15 Example 15
Eight grams of [ChCl] [SnCl2] 3 low eutectic solvent and18.2 g (0.18 mol) of valeric acid were combined with 23.9g (0.33 mol) of tert-butanol into the reactionbottle,Stirring,The control temperature is 80 ,Take 1 μL sample into the sample,The yield of tert-butyl valerate in the reactants wasdetermined by gas chromatography,The column was HP5MS.The specific test conditions are: chamber temperature 120 ,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 tert-butyl valerate was93% under the above reaction conditions,Selectivity is 100%.The reaction was carried out for 12 hours,The reaction solution was allowed to stand,The upper organic phase obtained by the separation was theesterification reaction product of tert-butyl valerate.The low-temperature eutectic solvent of the lower layer canbe reused after simple water removal.
