Problems solved by technology

This process has many reaction steps, and it needs to go through three steps of crystallization, filtration and crushing to get the finished product. The crystallization reaction takes more than 24 hours, and the amount of ethanol consumed is 5-8 times that of diethyl hexanoate essential oil. The entire production process equipment Complexity, high energy consumption, raw material consumption and labor costs

Embodiment 1

[0016] Example 1: First, an amine fresh ester crude oil is added to the amine fresh ester preheating kettle 1, which initiates a preheating kettle heating device, and the amine fresh ester crude oil in the preheating kettle is heated to 70 ° C; add it to the curing reaction kettle 3 400kg of powdered citric acid, the stirring blade 3 was stirred while stirring, and the amine nranin crude oil in the preheating kettle was input from the feed port to the curing reaction kettle, and the amount of the amine fresh ester crude oil was controlled at 15 liters / minute; organic The addition of methanol in the auxiliary storage tank is 60 liters, while the amine fresh ester crude oil is introduced, the methanol in the organic censoon tank is passed into the cured reaction kettle, which is continuously stirred for 30 minutes to the kettle temperature of 70 ° C. Methanol is continued, and the methanol is added to 0.5-1 liters / minute, and the cooling water is accessed into the cooled reactio...

Embodiment 2

[0018] Example 2: The amine fresh ester oil 500 kg is added to the amine fresh ester preheating kettle 1, and the preheating kettle heating means is activated, and the amine fresh ester crude oil in the preheating kettle is heated to 70 ° C; add it to the curing reaction kettle 3 400kg of powdered citric acid, the stirring blade 3 was stirred while stirring, and the amine fresh ester crude oil in the preheating kettle was input from the feed port to the cured reaction kettle, and the amount of the amine fresh ester crude oil was controlled at 20 liters / minute; organic Ethanol is added to 90 liters of ethanol, while the amine fresh ester crude oil is introduced, and the ethanol of the organic aid storage tank is inserted into the curing reaction kettle, and the mixture is continuously stirred at 25 minutes to the kettle temperature of 60 ° C; In ethanol, control ethanol is 0.5-1 liters per minute, and through the cooling line 6 into the cooled water jacket into the cooled reactio...

Abstract

A production process of diethyl aminoethyl hexanoate citrate comprises the following steps: 1, adding diethyl aminoethyl hexanoate crude oil into a diethyl aminoethyl hexanoate preheating kettle; 2, adding powdery citric acid into a curing reaction kettle with a stirrer, starting stirring, introducing the preheated diethyl aminoethyl hexanoate crude oil in step 1 into the curing reaction kettle from a feeding pipeline of the curing reaction kettle, and adding an organic auxiliary agent into the curing reaction kettle through an auxiliary agent feeding hole in the curing reaction kettle; 3, continuing to introduce the organic auxiliary agent, and introducing cooling water into the jacket of the curing reaction kettle for cooling until the temperature in the kettle is reduced to 30-40 DEG C; and 4, opening a discharge port at the bottom of the curing reaction kettle for discharging. The production process of diethylaminoethyl hexanoate citrate adopts a one-pot method, can obtain the powdery diethylaminoethyl hexanoate citrate finished product through one-time reaction, does not need filtering and crushing operation, and is low in raw material consumption, low in production energy consumption and short in production period.

Description

Technical field [0001] The present invention relates to an amine fresh ester citrate production process, belonging to the technical field of pesticide production. Background technique [0002] Amine fresh ester (also known alkyl ethyleneethanol) is an alternative product of plant growth regulators arseniacline, growth perisulin, naphthalene, adenine, and the like. The amine fresh ester itself is not a plant hormone, but after the plant absorbs, the activity of growthin, cytokinum, gibberein, peatum acid, ethylene, etc. can be adjusted, which allows plants to hopatically Direction development. In active applications in agriculture, the amine fresh esters are generally required to be in the form of solid citrate to facilitate administration. At present, the production process of amine fresh ester citrate is generally added citric acid to an amine ester crude oil, reacts in an ethanol solvent and reacts, and filters the filter cake to extract the filter cake to obtain an amine nrani...
