Embodiment 1
[0049] Take 70g (0.4mol) of dimethyl adipate and put it into a 500ml three-necked flask, add 210g of diethylene glycol dimethyl ether, add 23g (0.43mol) of sodium methoxide under stirring, heat to 50°C and react under reduced pressure for 3 hours , after the reaction was complete, the solvent was distilled off. H 2 SO 4Neutralize to neutral, separate the oil layer, and the oil layer is subjected to vacuum distillation to separate 40g of the intermediate product B, put the intermediate product into a 500ml there-necked flask, add 15.2g of sodium methylate, add 140g of tert-butanol, under reflux (80 -85°C) was added dropwise into 49g of bromohexane, reacted for 24h, after the reaction was completed, distilled off tert-butanol, and used H 2 SO 4 Neutralize to neutral, separate the oil layer, distill under reduced pressure, carry out acid decomposition under heating with concentrated NaOH solution, H 2 SO 4 After neutralization, it was washed and dried to obtain 47 g of 2-hex...
Embodiment 2
[0051] Take 70g (0.4mol) of dimethyl adipate and put it into a 500ml three-necked flask, add 210g of diethylene glycol dimethyl ether, add 23g (0.43mol) of sodium methoxide under stirring, heat to 50°C and react under reduced pressure for 3h, After the reaction was completed, the solvent was distilled off, and the residue was washed with H 2 SO 4 Neutralize to neutral, separate the oil layer, and the oil layer is subjected to vacuum distillation to separate 41g of the intermediate product B, put the intermediate product into a 500ml three-necked flask, add 15.6g of sodium formate, add 140g of tert-butanol, under reflux (80~ 85°C) into 42g of bromobutane dropwise, and reacted for 24 hours. After the reaction was completed, tert-butanol was evaporated, and H 2 SO 4 Neutralized to neutral, separate oil layer. Vacuum distillation. Acid decomposition under heating with concentrated NaOH solution, H 2 SO 4 After neutralization, it was washed and dried to obtain 37 g of 2-butyl...
Embodiment 3
[0056] The acid obtained in Example 1 is made into ammonium salt and made into 250 g of 5% ethylene glycol solution, then 0.1% ammonium hypophosphite and 0.4% p-nitrobenzyl alcohol are added to make electrolyte, packed into a 500ml stainless steel bottle, sealed , Constant temperature at 105 ℃ and then test the parameters.
