Embodiment 1

[0023] Example 1 Synthesis of 2-(2-methoxy-5-nitro-phenoxy) ethyl triethyl ammonium bromide a, 2-(2-bromoethoxy)-4-nitrobenzene Synthesis of Methyl Ether

[0024] In a 1L reaction kettle, add 169g of 5-nitroguaiacol sodium, 740g of 1,2-dibromoethane, 2.0g of 1-butyl-3-methylimidazolium bromide, and 30% hydrogen by mass Sodium oxide solution 200g. Heated to 100°C for 6h. Cool down to room temperature, transfer the feed liquid into a separatory funnel, let stand to separate layers, collect the organic layer, and recover 520 g of excess 1,2-dibromoethane by rotary evaporation, and recrystallize the residue to obtain intermediate 2-(2-bromoethane Ethoxy)-4-nitroanisole 199g, yield 82%. B, the preparation of 2-(2-methoxy-5-nitro-phenoxy) ethyl triethyl ammonium bromide

[0025] In the autoclave, 100 g of intermediate 2-(2-bromoethoxy)-4-nitroanisole and 183 g of triethylamine were added. Start stirring and control the rotation speed at about 800r / min, and heat to 110°C for 24h...

Abstract

Belonging to the technical field of agrochemistry, the invention relates to a novel plant growth regulator 2-(2-methoxy-5-nitro-phenoxy)ethyltriethylammonium halide, a preparation method and application thereof. The structure of the compound is shown as the formula in the specification. The compound is respectively subjected to biological activity experiments on monocotyledonous plant wheat and dicotyledonous plant soybeans, and the results show that the compound has an obvious plant growth promoting effect when the concentration is low, has certain inhibiting effect when the concentration ishigh, and the compound is a broad-spectrum plant growth regulator. And the production process is simple, is easy to realize industrial production, and provides a new choice for plant growth regulator.

Description

technical field [0001] The invention relates to the technical field of agrochemicals, in particular to 2-(2-methoxy-5-nitro-phenoxy)ethyltriethylamine halide, a preparation method thereof and application as a plant growth regulator. Background technique [0002] Plant growth regulators can regulate and control different stages of plant growth and development, such as germination, rooting, cell elongation, organ differentiation, flower bud differentiation, flowering, fruiting, defoliation, dormancy, etc. Some of them can increase the protein and sugar content of plants, some can change their shape, and some can enhance the ability of plants to resist cold, drought, salinity and pests. [0003] Plant growth regulators can be obtained by artificial synthesis, the cost is relatively reduced, and the application is more convenient. Diethylaminoethanol ester), sodium nitrophenolate, tributuron and so on. At present, there are many studies on plant growth regulators, but most of ...
