| Physical and Chemical Properties | The pure chemical product is white crystal. M. p.86.5 ~ 86.8 ℃ (80 ℃ for industrial products). Solubility: dichloroethylene 1000g/L, xylene 780g/L, ethanol 14g/L. Insoluble in water. Stable chemical properties, decomposition in case of strong alkali. |
| Use | Use 1, many food plant mites and eggs have higher activity, there is a significant residual egg killing activity, micro insecticidal activity. For cotton, fruit on a variety of mites, generally no damage. It can also be used as an anti-moths agent for wool textiles. 2. The product was first sold by the Swiss company, jiaki, as an anti-decay agent for wool goods. Acaricidal Ester has a good effect on the control of mite eggs and juvenile mites, and is used to control various mites on cotton and fruit trees. |

Toxicity
the acute oral LD50 of rats is 2000mg/kg, and the rats fed with 300mg/kg feed for 130 days have no obvious adverse effects.
production method
1, using p-chlorobenzenesulfonic acid and chlorosulfonic acid as raw materials, the following steps are used to produce acaricide. The content of acaricidal ester industrial products is more than 95%. Raw material consumption quota: p-chlorobenzenesulfonic acid (92%)1230 kg/t, chlorosulfonic acid (95%)2100 kg/t, phenol (98%)310 kg/t, sodium hydroxide (95%)157 kg/t, chlorine (99.5%) 250 kg/t, ferric chloride (99%)1.8 kg/t.
2. preparation method 1
using p-chlorobenzenesulfonic acid and chlorosulfonic acid as raw materials, the acaricide is synthesized by the following steps.
Preparation method II
Using p-chlorophenol and p-chlorobenzenesulfonyl chloride as raw materials, acaricide is synthesized under alkaline conditions.
