use	can be used as disinfectant or organic synthesis intermediate the product is condensed with chloroacetic acid to obtain p-iodophenoxyacetic acid. This is a plant growth regulator, also known as Zengzanling; it is also used for fattening and fattening of live pigs, so it is also called Fat Pig Spirit. P-iodophenol is also used in other organic synthesis.
production method	is obtained by diazotization and replacement of p-aminophenol. The mixed solution of p-aminophenol, water and sulfuric acid is cooled to 0 ℃, and the sodium nitrite solution is added within 1h under stirring. After adding, continue stirring for 20min, then add concentrated sulfuric acid to obtain diazotized solution. Pour the diazotization solution into the cold potassium iodide solution, add copper powder, and stir at 75-80 ℃, and react until no nitrogen is released. Cool to room temperature, extract three times with chloroform, combine the extract, and wash with a dilute solution of sodium thiosulfate. Recover chloroform by distillation. The distilled residue was distilled under reduced pressure, and the fraction at 135-140 ℃(61.3kPa) was collected, and cooled and crystallized to obtain crude p-iodophenol. Crystallized with dilute ethanol to make fine products. The yield is about 70%.
