Uses
3,5-Dichlorophenol(591-35-5) is mainly used for the production of herbicides such as wheat straw Dan and DP fungicide.
Production
Can be with 2,5 - dichloro-aniline as the raw material, add sulfuric acid and sodium nitrite to diazotization and then obtained by the hydrolysis.
Can also be used 1,2,4 - trichlorobenzene as raw material,and,at a certain temperature and pressure, add caustic soda and solvents under the hydrolysis reaction ,using hydrochloric acid, and then separation of urea additive derived.
