Embodiment 1

[0032] Example 1 Add 14.6g (0.1mol) adipic acid, 35.1g (0.3mol) N,N-diethylaminoethanol, 0.8g sulfuric acid in a 250ml four-necked flask equipped with a stirrer, water separator and reflux device Titanium oxide, 20ml xylene, stirred and heated to 150°C and refluxed for 5h until 3.6g (0.2mol) of water was separated, filtered to remove the catalyst (directly reused), the filtrate was transferred to another 250ml three-necked flask, and distilled under reduced pressure After removing the solvent (for recycling), excess diethylaminoethanol (for recycling) and low boiling point substances, add 3.0g of activated clay and stir for 30 minutes, cool down to below 80°C, and filter to obtain yellow oily liquid diethylamine adipate Ethanol ester 31.10g, productive rate is 90.4%. Then mix bis-diethylaminoethanol adipate and twice the mole of citric acid, stir and heat to 120°C, melt the citric acid, cool and crystallize under stirring to form a white powdery solid product, bis-diethyl adip...

Embodiment 2

[0033]Example 2 Add 14.6g (0.1mol) of adipic acid, 23.4g (0.2mol) of N,N-diethylaminoethanol, 0.8g of sulfuric acid in a 250ml four-necked flask equipped with a stirrer, water separator and reflux device Titanium oxide, 40ml xylene, stirred and heated to 140°C and refluxed for 8 hours until 3.6g (0.2mol) of water was separated, filtered to remove the catalyst (directly reused), the filtrate was transferred to another 250ml three-necked flask, and distilled under reduced pressure After removing the solvent (for recycling) and low boiling point substances, add 3.0g activated clay and stir for 30 minutes, cool down to below 80°C, and filter to obtain 29.55g of yellow oily liquid bis-diethylaminoethanol adipate, with a yield of 85.9% . Then mix bis-diethylaminoethanol adipate and twice the mole of citric acid, stir and heat to 120°C, melt the citric acid, cool and crystallize under stirring to form a white powdery solid product, bis-diethyl adipate Diethylaminoethanol Citrate.

Abstract

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.

Description

technical field [0001] The invention relates to a novel plant growth regulator bis-diethylaminoethanol adipate citrate compound and a preparation method thereof. The compound has the purposes of promoting seed germination, promoting plant growth, enhancing photosynthesis, increasing crop yield, improving fruit quality, enhancing plant stress resistance and the like. Background technique [0002] my country began to study plant growth regulators from promoting cutting rooting in 1937, but before 1949, it was not used in production. After 1949, 2,4-dichlorophenoxyacetic acid and naphthaleneacetic acid were introduced from abroad and applied to crops such as apples and tomatoes to prevent flower and fruit drop. In the late 1950s, due to the successful development of phenol regulators, the scope of application was further expanded. In the 1960s, the types and objects of application increased again, but mainly focused on the application of chlormequat in cotton and wheat. Sinc...
