Description
Technical field
The invention belongs to chemical technology field, and in particular to a kind of removal technique of the glycine zine crystallization water.
Background technology
Glycine zine is the additive of feed microelement, just gradually replaces zinc sulfate, the standard of glycine zine be zinc >=
21%, total glycine amount >=23%, water≤10%.Basic zinc carbonate or zinc sulfate and glycine generation chela can be used by producing glycine zine
Compound.Use ZnSO4·H2The glycine zine of O synthesis contains the 15-16% crystallization water, does not reach standard.Generally removing the crystallization water has
Several method：First, drying temperature is improved in process of production to more than 120 DEG C, but more than more than 80 DEG C glycine zines can divide
Solution, the method do not apply to glycine zine；Another method is vacuum drying, but this method is invested, and is unfavorable for promoting；Also one
Kind of method is that product is dissolved in ethanol azeotropic dehydration, but changes method and do not allow in cost secure context, investing.Therefore need to grind
Study carefully that a kind of dehydrating effect is good, the removal technique of low, product safety the glycine zine crystallization water of investment.
The content of the invention
It is an object of the present invention in view of the above-mentioned problems, a kind of dehydrating effect of offer is good, invests low, product safety
The glycine zine crystallization water removal technique.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of removal technique of the glycine zine crystallization water, comprises the following steps：
By 100:60:24:1-2.5 weight part ratio is fetched water respectively, ZnSO4.H2O, glycine and neopelex, first
Water is placed in a vessel in heating to 50-65 DEG C, is then charged with ZnSO4.H2O, stirring make ZnSO4.H2O is completely dissolved
After add glycine, this is system 1, system 1 is stopped heating after reacting 30-40min under conditions of 50-65 DEG C, obtains body
It is 2, system 2 is carried out to be concentrated to give system 3；Then toward adding neopelex in system 3, and it is stirred continuously to body
It is that 3 coolings separate out crystal, then filters to take its crystal, finally dry crystal, produce the glycine zine for removing the crystallization water.
In the present invention, further instruction, a kind of removal technique of the glycine zine crystallization water, including following step
Suddenly：
By 100:60:24:1.8-2 weight part ratio is fetched water respectively, ZnSO4.H2O, glycine and neopelex, first
Water is placed in a vessel in heating to 55-60 DEG C, is then charged with ZnSO4.H2O, stirring make ZnSO4.H2O is completely dissolved
After add glycine, this is system 1, system 1 is stopped heating after reacting 34-37min under conditions of 55-60 DEG C, obtains body
It is 2, system 2 is carried out to be concentrated to give system 3；Then toward adding neopelex in system 3, and it is stirred continuously to body
It is that 3 coolings separate out crystal, then filters to take its crystal, finally dry crystal, produce the glycine zine for removing the crystallization water.
In the present invention, further instruction, the volume of system 3 are the 45-55% of the system 2.
In the present invention, further instruction, the crystal baking step, its drying condition are 55-65 DEG C, drying time
For 3.5-4.5h.
In the present invention, further instruction, the volume of system 3 are the 48-52% of the system 2.
In the present invention, further instruction, the crystal baking step, its drying condition are 58-62 DEG C, drying time
For 3.8-4.2h.
The present invention has the advantage that compared with prior art：
1. the present invention by being produced in glycine zine during add auxiliary agent reach good dehydrating effect.Added in the present invention
Auxiliary agent be neopelex, a neopelex molecule part is polarity, and a part is nonpolar, polarity
Part is close with the zinc of glycine zine, and nonpolar moiety molecular chain length, can effectively prevent water from generating the crystallization water with glycine zine,
So as to reduce moisture content.
2. glycine zine removal crystallization water technology investment of the present invention is low, and product safety.The auxiliary agent dodecane added
Base benzene sulfonic acid sodium salt is cheap, reduces cost of investment.Neopelex contains part and glycine zine cocrystallization, but
Less than 1 percent, other indexs of glycine zine are not influenceed, obtained glycine zine product safety.The present invention removes glycine
The product safety that zinc crystallization water effect is good, investment is low and obtains, has very big promotional value.
