at 110; for 6 h;

Steps:

14 Example 14

A mixture of 24 grams of [ChCl] [ZnCl2] 2 eutectic solventand 70.85 grams (0.60 mol) of succinic acid with 55.81 grams (0.50 mole)N-heptanol into the reaction bottle,Stirring,The control temperature was 110 ° C,Reaction for 6 hours,Take 1 μL sample into the sample,The yield of di-n-heptyl succinate in thereactants was determined 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 di-n-heptyl succinate under the abovereaction conditions was 95%Selectivity is 100%.The reaction solution was allowed to stand,And the upper organic phase obtained by the liquidseparation is the esterification reaction product n-diheptyl succinate.The low-temperature eutectic solvent of the lower layer canbe reused after simple water removal.
