Problems solved by technology

Among them, the solid acid catalysis method has a high yield, but the preparation of the catalyst is cumbersome and the production process is complicated; the organic acid catalysis method has a low yield, and the salt formed by the catalyst and diethylaminoethanol is miscible with the reaction system, so post-treatment is difficult; The price of tetrabutyl phthalate used in the non-acid catalyst catalytic method report is more expensive and the cost is higher

Embodiment 1

[0036] A plant growth regulator caprylic acid-N, the preparation of N-diethylaminoethyl ester hydrochloride comprises the steps:

[0037] In the there-necked flask, add 200 grams of diethylaminoethanol, dissolve in dichloromethane, stir and cool down in a cryogenic cold trap, then add 10 grams of sodium bicarbonate, and when the temperature is lowered to 0 degrees Celsius, add 250 grams of octanoyl chloride dropwise, Adding time is 1 hour, and the dropping temperature is controlled at -10 to 20 degrees Celsius; react at low temperature for two hours, then stir at room temperature for three hours, stop stirring, and remove the solvent to obtain caprylic acid-N,N-diethylaminoethyl ester Hydrochloride.

Embodiment 2

[0039] In the three-neck flask, add 100 grams of diethylaminoethanol, stir in the cryogenic cold trap to cool down, when the temperature drops to 0 degrees Celsius, add 150 grams of octanoyl chloride dropwise, the dropping time is 1 hour, and the dropping temperature is controlled at -10 to 20 degrees Celsius . React at low temperature for 3 hours, then stir at 40-60 degrees Celsius for 2 hours, stop stirring, discharge, and cool slightly to obtain octanoic acid-N,N-diethylaminoethyl ester hydrochloride as a white solid.

Embodiment 3

[0041] A plant growth regulator octanoic acid-N, the preparation of N-diethylaminoethyl citrate comprises the steps:

[0042] Step 1, preparation of octanoic acid-N,N-diethylaminoethyl ester hydrochloride: in a three-necked flask, add 200 grams of diethylaminoethanol, dissolve in dichloromethane, stir and cool down in a cryogenic cold trap, and cool down When the temperature reaches 0 degrees Celsius, 280 grams of octanoyl chloride is added dropwise for 1 hour, and the dropping temperature is controlled at -10 to 20 degrees Celsius. React at low temperature for two hours, then stir at room temperature for three hours, stop stirring, and remove the solvent to obtain octanoic acid-N,N-diethylaminoethyl ester hydrochloride.

[0043] Step 2, alkali neutralization and extraction to obtain octanoic acid-N,N-diethylaminoethyl ester: preferably use aqueous sodium bicarbonate as a base to neutralize octanoic acid-N,N-diethylaminoethyl ester salt obtained in step 1 salt, and extracted ...

Abstract

The invention discloses a preparation method of a plant growth regulator N,N-diethylaminoethyl caprylate. The preparation method comprises the following steps: 1, preparing N,N-diethylaminoethyl caprylate hydrochloride by using a reaction chemical formula shown in the specification; 2, carrying out alkali neutralization and extraction to obtain N,N-diethylaminoethyl caprylate; and 3, preparing N,N-diethylaminoethyl caprylate citrate by using a solvent method or a solvent-free method. During use, the N,N-diethylaminoethyl caprylate hydrochloride and the N,N-diethylaminoethyl caprylate citrate can be used for spraying, irrigating and spraying agricultural products, commercial crops and fruits. The N, N-diethylaminoethyl caprylate salt is prepared through a reaction at a low temperature, andthe raw materials are easy to obtain and low in price, so the synthesis method is simple and safe, and the yield is high; in the salifying process, the use of a solvent is reduced, so the cost is saved; and the reaction time is short, so the efficiency is high, energy is saved, and the method is suitable for industrial production.

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 octanoic acid-N,N-diethylaminoethyl ester salt. Background technique [0002] Plant growth regulator commonly used in the prior art is DA-6, has another name called diethyl aminoethyl hexanoate, and it is a kind of high-efficiency plant growth regulator with broad-spectrum effect. It can increase the activity of plant peroxidase and nitrate reductase, increase the content of chlorophyll, accelerate the speed of photosynthesis, promote the division and elongation of plant cells, promote the development of root system, and regulate the balance of nutrients in the body. [0003] In modern agriculture, plant growth regulators are widely used in food crops, economic crops, fruit trees, vegetables, flowers and edible fungi, etc. The use of low concentrations can greatly increase the yield of crops and signific...
