example 1
[0029] 9 mg (0.1 mmol) sodium diformylamide Dissolve in 25mL N, N-dimethylformamide solvent to obtain dechlorinating agent solution. Add an appropriate amount of dichloromethane to 100 mL of naphtha with an organic chlorine content of less than 1 mg / kg and mix well to prepare a dichloromethane naphtha solution with an organic chlorine content of 100 mg / kg, wherein the chlorine content is 0.2 mmol.
[0030] Place the container containing the above-mentioned chlorinated naphtha on a stirring table, and under the condition of magnetic stirring, add 25mL dechlorination agent solution dropwise to 100mL chlorinated naphtha at a uniform speed at 25°C to carry out the dechlorination reaction. The dechlorination agent solution was added dropwise, and the reaction was carried out for 0.5 hour. Then the mixed solution was transferred to a separatory funnel and allowed to stand for 5 minutes to separate the lower layer of N,N-dimethylformamide solution from the upper layer of naphtha. ...

[0032] Dissolve 18 mg (0.2 mmol) of sodium diformamide in 25 mL of N,N-dimethylformamide solvent to obtain a dechlorinating agent solution. Add an appropriate amount of 2-chloropropene to 100mL of naphtha with an organic chlorine content of less than 1mg / kg, and mix well to prepare a naphtha solution of 2-chloropropene with an organic chlorine content of 100mg / kg. 0.2 mmol.
[0033] Place the container containing the above-mentioned chlorinated naphtha on a stirring table, and under the condition of magnetic stirring, add 25mL dechlorination agent solution dropwise to 100mL chlorinated naphtha at a uniform speed at 25°C to carry out the dechlorination reaction. The dechlorination agent solution was added dropwise, and the reaction was carried out for 0.5 hour. Then the mixed solution was transferred to a separatory funnel and allowed to stand for 5 minutes to separate the lower layer of N,N-dimethylformamide solution from the upper layer of naphtha. Take 50mL of deionized wa...

[0035] Dissolve 18 mg (0.2 mmol) of sodium diformamide in 25 mL of N,N-dimethylformamide solvent to obtain a dechlorinating agent solution. Add an appropriate amount of p-dichlorobenzene to 100 mL of diesel oil with an organic chlorine content of less than 1 mg / kg and mix well to prepare a diesel solution of p-dichlorobenzene with an organic chlorine content of 100 mg / kg, in which the chlorine content is 0.22 mmol.
[0036]Place the container containing the above-mentioned chlorine-containing diesel oil on a stirring table, and under the condition of magnetic stirring and heating, add 25mL dechlorination agent solution dropwise at 40°C to 100mL chlorine-containing diesel oil at a uniform speed to carry out the dechlorination reaction. The dechlorination agent solution was added dropwise, and the reaction was carried out for 0.5 hour. Then the mixed solution was transferred to a separatory funnel and allowed to stand for 5 minutes to separate the lower layer N,N-dimethylformami...
