A compound of N- nitro-2,4,6-trifluoroaniline, synthesis method and application thereof

Abstract

The present invention discloses a compound of N-nitro-2,4,6-trifluoroaniline. The invention further discloses a synthesis method for the compound. The method comprises that: 2,4,6-trifluoroaniline is adopted as a raw material; the 2,4,6-trifluoroaniline reacts with nitric acid to generate 2,4,6-trifluoroaniline nitrate; the 2,4,6-trifluoroaniline nitrate and acetic anhydride are subjected to a dehydration reaction; the resulting reaction solution is subjected to alkaline washing and acid precipitation to obtain the N-nitro-2,4,6-trifluoroaniline. The invention further discloses an application of the compound as an active ingredient of a plant growth regulator. The compound provided by the present invention provides a more significant plant growth regulation effect than N-nitro-2,4,6-trichloroaniline and N-nitro-2,4,6-tribromaniline, and provides the high selectivity for the growth regulation of the rice root.

Description

technical field [0001] The present invention relates to the compound N-nitro-2,4,6-trifluoroaniline, and also relates to the synthesis method of the compound and its application as the active ingredient of the plant growth regulator. Background technique [0002] Barring Cross, Prithvi R.Bhalla etc. reported in the patent US4643755 that N-nitro-2,4,6-trisubstituted aniline compounds have the effect of inhibiting elongation and promoting stoutness on the stems of plants, and emphasized that N- Regulatory activity of nitro-2,4,6-tribromoaniline on dwarf and robustness of different growth stages of wheat and rice. Thomas D.O'Neal et al reported in the patent US4367339 that N-nitro-substituted aniline compounds and their inorganic salts and organic salts promote early flowering of ornamental plants, induce tillering and yield-increasing plant growth regulation activities of crops such as rice and wheat. [0003] In China, Professor Xie Jiugao of Huazhong Agricultural University...

Problems solved by technology

When the substituting element on the benzene ring in the molecule is a halogen, the biological activity of the molecule is relatively good. Three bromine atoms and three chlorine atoms have been successfully introduced into the 2, 4, and 6 positions of the benzene ring, but they have not been introduced at the same time. Three fluorine atoms give N-nitro-2,4,6-trifluoroaniline
