Paragraph 0031, (2017/01/02)
The invention relates to a plant growth regulator bis(diethylaminoethyl)adipate citrate compound and a preparing method thereof.The structure of the compound is shown as follow (see the formula in the description).The preparing method includes the steps that organic solvent is added into a reactor provided with a manifold and a reflux device, under the action of a catalyst, the molar ratio of adipic acid or adipic anhydride to N,N-diethylaminoethanol is controlled to be 1:2-1:3, reaction is conducted at the temperature of 110-150 DEG C in a reflux and water division mode, the product is filtered, reduced pressure distillation is conducted on filter liquor to obtain the organic solvent and excess diethylaminoethanol, a kettle substrate is decolored with activated clay to obtain bis(diethylaminoethyl)adipate, and bis(diethylaminoethyl)adipate reacts with citric acid to be salified so as to obtain the white solid product, wherein the mole number of citric acid is two times that of bis(diethylaminoethyl)adipate.The compound has the effects of promoting seed germination, enhancing photosynthesis, promoting plant growth, increasing crop yield, improving fruit quality, enhancing plant adverse resistance and the like and is a broad-spectrum active regulator.The production process is simple, and industrial production is easy to achieve.
