Teflubenzuron Chemical Properties,Uses,Production

Chemical properties

Pure Teflubenzuron is white crystal. m.p.223~225℃ (The original compound 222.5℃),saturated vapor pressure0.8×10-9Pa(20℃), relative density 1.68(20℃).  Its solubility at 20~23℃ are 66g/L in dimethyl sulfoxide, 20g/L in cyclohexanone, 10g/L in acetone, 1.4g/L in ethanol,  850mg/L in methylbenzene, 50mg/L in hexane,  0.02mg/L in water. Stable at room temperature. Its hydrolysis half-life period are 5d(pH=7)and 4h (pH=9) at 50℃ and 2~6 weeks in soil.

Uses

Teflubenzuron’s a fluorobenzoylurea insect growth regulator and a chitinase inhibitor. It achieves the insecticidal purpose through the inhibition of normal molting and development of larvae. It has a particularly high activity on lepidoptera pests, also achieves a good effect when it comes to the larvae of whitefly families, diptera, hymenoptera, coleoptera pests, but it’s invalid for many parasitic insects, predatory insects and spiders. It is mainly used on vegetables, fruit trees, cotton and teabush. E.g. 2000~4000 times diluent of EC can be applied by spraying to larvae of cabbage caterpillar and plutella xylostella in the egg incubation period to 1 to 2 instar.1500~3000 times diluent of EC can be applied by spraying to larvae of plutella xylostella, asparagus caterpillar, prodenia litura in the egg incubation period to 1 to 2 instar, which are resistant to organic phosphorus and pyrethroids. 1500~2000 times diluent of EC can be applied by spraying to cotton bollworm and pink worm in the egg incubation period of the second and third generations, and the elimination rate is about 85% after 10 days.

Production Method

Method 1
The addition reaction of 2,6-Difluorobenzamide and 2,4-difluoro-3,5-dichlorophenyl isocyanate
Method 2
preparation of 2,4-Difluoro-3,5-dichlorophenylamine
2,3,4,5-tetrachloronitrobenzene and Potassium fluoride react in DMF solvent at 140℃ for 15h to obtain 2,4-Difluoro-3,5-dichloronitrobenzene,which is then reduced to 2,4-Difluoro-3,5-dichlorophenylamine
Preparation of Teflubenzuron
 As for the preparation of 2,6-difluorobenzoyl isocyanate, see details in the preparation of  Teflubenzuron.
 2,6-difluorobenzoyl isocyanate and 2,4-Difluoro-3,5-dichlorophenylamine react at room temperature for 15h to obtain Teflubenzuron
 As for the nitrification, chlorination, reduction, fluorization and condensation of 1,2,4-Trichlorobenzene to  prepare Teflubenzuron, see details in bibliography.
