Yield:1917-96-0 317.77 g

Reaction Conditions:

with 3,4-dichlorothiophene;sulfuryl dichloride;titanium tetrachloride at 70; for 0.5 h;Large scale;

Steps:

9

Adding 0.90 g of 99% titanium tetrachloride to n-heptyl phenoxyacetate,2.58g of 99% 3,4-dichlorothiophene,273.29 g of 99% sulfuryl chloride was added dropwise at 70 ° C to react.After the addition, the reaction was kept at this temperature for 0.5 h.Distilling at a pressure of 1 kPa and collecting fractions at 145-155 ° C,317.77 g of n-heptyl 2,4-dichlorophenoxyacetate was obtained, and the purity was 98.94%.
