4-Iodophenoxyacetic acid Use and Manufacturing

Methods of Manufacturing

Using p-aminophenol as raw material, p-iodophenol is generated by diazotization and replacement, and then condensed with chloroacetic acid to obtain iodobenzene ethoxy acid. Slowly add the sodium nitrite solution to the mixture of p-aminophenol, water and sulfuric acid at -5°C, and then continue the reaction for 20 minutes. Add the diazotization solution and the copper powder to the potassium iodide solution successively, and react at 75-80°C until no nitrogen escapes. After cooling, it is extracted with chloroform, the extract is washed with sodium thiosulfate solution, and the chloroform is recovered by distillation, and the fraction at 135-140°C (61.3kPa) is collected, which is p-iodophenol. Add p-iodophenol and chloroacetic acid to sodium hydroxide solution and react at 100°C for 3-6h. After cooling slightly, add hydrochloric acid to adjust the pH to 3-5. Extract with ether, wash the extract with water, and then neutralize into sodium salt with sodium carbonate solution. The water layer was separated and acidified with hydrochloric acid to precipitate crystals. After separation, it is recrystallized with 50% ethanol to obtain p-iodophenoxyacetic acid product.

Uses

As a growth-promoting agent, it can promote the metabolism of the pig's body, accelerating fattening and increasing fat. Used as a plant growth regulator, has the effect of accelerating cell division and differentiation
