Abstract
The invention discloses a kind of preparation method of the ferrisodium of ethylenediamine two, comprise the following steps：（1）To 5 ~ 6 times of water of weight are added in NaOH, stirring dissolves NaOH, obtains solution I；（2）To metacresol, glyoxalic acid, ethylenediamine and ferric nitrate is sequentially added in solution I, 2 ~ 3h is reacted under conditions of 60 ~ 65 DEG C, dry to obtain the ferrisodium of ethylenediamine two.
Description
Technical field
The invention belongs to chemical industry synthesis field, and in particular to a kind of preparation method of the ferrisodium of ethylenediamine two.
Background technology
Ferro element plays the role of important in growing process, and during iron deficiency, plant tender tip blade is thinning, leaf is small, mesophyll
Jaundice, when serious, leaf abscission influences crop yield.In nature, the ferro element for largely existing, but deposited with oxide
Water insoluble, it is impossible to be absorbed by plants, not only yield is low for the existing technique for preparing the ferrisodium of ethylenediamine two, and purity is low, is produced into
This height, while being also unfavorable for plant absorption.
The content of the invention
For above-mentioned deficiency of the prior art, the present invention provides a kind of preparation method of the ferrisodium of ethylenediamine two, using this
The method of invention, can obtain high-purity and the ferrisodium of ethylenediamine in high yield two.
To solve above-mentioned technical problem, the technical solution adopted by the present invention is
A kind of preparation method of the ferrisodium of ethylenediamine two, comprises the following steps：
（1）To 5 ~ 6 times of water of weight are added in NaOH, stirring dissolves NaOH, obtains solution I；
（2）To metacresol, glyoxalic acid, ethylenediamine and ferric nitrate is sequentially added in solution I, 2 are reacted under conditions of 60 ~ 65 DEG C
~ 3h, dries to obtain the ferrisodium of ethylenediamine two.
Further, the weight ratio of water, metacresol, NaOH, glyoxalic acid, ethylenediamine and ferric nitrate is 5 ~ 6:1~2.5:
1~2:1~2.5:1~1.5:1~2。
Further, the weight ratio of water, metacresol, NaOH, glyoxalic acid, ethylenediamine and ferric nitrate is 6:1.95:
1.07:2:1.05:0.33。
The ferrisodium of ethylenediamine two that above-mentioned preparation method is prepared.
Beneficial effects of the present invention are：
This product belongs to chelating amino acids agent, and its applicable pH value range is wide, and in pH value is for 3 ~ 10 soil, absorptivity is high, in state
It is interior mainly to apply to prevent and treat the yellows that plant iron deficiency is caused；Can also be used for normal plants and mend iron, plant growth can be made more vigorous,
Increase yield and improve fruit quality.
The present invention, as solvent, can be prevented effectively from and produce pollution to environment using water, be reclaimed without to solvent, be dropped
Low production cost.
Specific embodiment
Specific embodiment of the invention is described below, this hair is understood in order to those skilled in the art
It is bright, it should be apparent that the invention is not restricted to the scope of specific embodiment, for those skilled in the art,
