use | as a plant growth promoter, China stipulates that it is only used for bean sprouts, and the residual amount shall not exceed 1.0 mg/kg. Used as plant growth regulator |
production method | using p-chlorophenol and chloroacetic acid as raw materials, the finished product is obtained by condensation and refining under alkaline conditions. Phenol is used as raw material to place phenol in a reaction kettle, heat and melt, add 15% sodium hydroxide, then add a mixed aqueous solution of chloroacetic acid and sodium carbonate, and heat and reflux for 4 hours. After the reactant is cooled, it is neutralized and acidified with hydrochloric acid to a pH value of 2~3 to generate phenoxyacetic acid with a yield of more than 82%. Phenoxyacetic acid is dissolved in glacial acetic acid, and under the catalysis of iodine, chlorine gas is slowly introduced at 26~34 ℃. The reactant is left overnight, p-chlorophenoxyacetic acid is precipitated in cold water, filtered, washed to neutral and dried, p-chlorophenoxyacetic acid is neutralized with sodium carbonate to obtain sodium salt. |
White needle-like or diamond-like crystals, slightly phenolic. The melting point was 154-156 °c. Soluble in water. Stable in nature.
obtained by condensation, chlorination and neutralization of phenol and chloroacetic acid under alkaline conditions. It can also be obtained by condensation and purification of p-chlorophenol and chloroacetic acid as raw materials under alkaline conditions.
used as a growth promoter. At low concentration, it can promote the growth of plants, especially the effect of double leaves plants, but it has inhibitory effect at high concentration. For bean sprouts, residues should not exceed 1.0 mg/kg.
