Preparation and application of plant growth regulator N,N-diethylaminoethyl butyrate

Abstract

The invention discloses a preparation method of a plant growth regulator N,N-diethylaminoethyl butyrate. The preparation method comprises the following steps: 1, preparing N,N-diethylaminoethyl butyrate hydrochloride according to a reaction principle shown in the description; 2, carrying out alkali neutralization and extraction to obtain N,N-diethylaminoethyl butyrate; and 3, preparing N,N-diethylaminoethyl butyrate citrate by using a solvent method or a solvent-free method. The intermediate N,N-diethylaminoethyl butyrate hydrochloride and the finally obtained N,N-diethylaminoethyl butyrate citrate can be used as plant growth regulators to be applied, and specifically, the intermediate N,N-diethylaminoethyl butyrate hydrochloride and the finally obtained N,N-diethylaminoethyl butyrate citrate are sprayed or irrigated to crops, commercial crops and fruit plants. The N,N-diethylaminoethyl butyrate is prepared through a low-temperature normal-pressure reaction, and the raw materials are easy to obtain and are low in price, so the preparation method is simple, convenient and feasible; and the using method is simple, and the N,N-diethylaminoethyl butyrate can be compounded with multiplecomponents according to different purposes, so the application field of the N,N-diethylaminoethyl butyrate is expanded, efficiency is high, and cost is low.

Description

technical field [0001] The invention relates to the fields of chemical industry and agriculture, in particular to the preparation and application of a plant growth regulator butyric acid-N,N-diethylaminoethyl ester salt. Background technique [0002] N, N-diethylaminoethanol hexanoate (being commonly called as DA-6) is as efficient plant growth regulator in the prior art, has the multiple functions of auxin, gibberellin and cytokinin, by enhancing plant photosynthesis and Plant enzyme activity can promote cell division, elongation and plant carbon and nitrogen metabolism, etc. It has the effects of increasing yield, early maturity, improving quality, disease resistance and stress resistance. It can induce the synthesis of β-carotene in plants and increase the content of β-carotene; it can also greatly increase the yield of crops and significantly improve the quality of products; and it has high efficiency, low toxicity, safe use, and low production and use costs. It has bee...

Problems solved by technology

[0003] In recent years, the research and application of plant growth regulators in my country have also developed rapidly, but their varieties and quantities cannot meet the needs of the market.

In many areas of our country, the problem of rotten seeds and lack of seedlings of vegetables and flowers has been very serious. The main reason is that after the seeds are harvested, the vigor of the seeds is easily reduced or even lost during the drying and storage process.
