Abstract
The present invention relates to a kind of preparation methods of alanine iron complex additive, belong to third generation microelement feed addictive --- amino-acid trace element iron complex preparation technical field.It the steps include: to choose alanine and ferrous nitrate in molar ratio for 1: 1-1.5；It is first that alanine is soluble in water, it is heated to 60-80 DEG C, keeps constant temperature, ferrous nitrate is then added and keeps stirring, reacts 0.5-1.0 hours；Then it is cooled to 25-35 DEG C, the crystallization of alanine iron is precipitated；Mother liquid recycling.Advantages of the present invention are as follows: 1. are not added alkali, do not have to catalyst, in a water bath through being complexed；2. reaction speed is fast, the oxidation of ferrous nitrate is avoided；3. product can direct crystallization precipitation.4. mother liquid recycling.
Description
Technical field
The present invention relates to a kind of preparation methods of alanine iron complex additive, belong to third generation microelement feed and add
Add agent amino-acid trace element iron complex preparation technical field.
Background technique
Alanine iron complex is at home and abroad to develop faster latest model feed addictive in recent years, it is growth of animal
Necessary iron metal ion reacts the complex or chelate with cyclic structure generated with alanine.Since it connects
It is bordering on the supplements-iron of natural form in animal body, and there is good chemical stability, higher biological value, dissolubility
It is high, easy to digest absorb, the characteristics such as anti-interference, non-stimulated, nonhazardous effect, be presently believed to be a kind of ideal iron addition
Agent.Currently, the production method of alanine iron complex mainly by reaction phase in addition lye adjust pH, be passed through nitrogen or
Add antioxidant, anti-caking agent etc..Generally existing complex process, yield are low, product quality is uncontrollable, high expensive etc. is asked
Topic, it is difficult to promote and apply in practice.The synthetic route for finding a simple process, it is extremely urgent to reduce cost.
Summary of the invention
The purpose of the present invention is to provide a kind of simple production process, high income, product qualities to be easy to control, cost is relatively low
Alanine iron complex preparation method.
The present invention is realized by following measures:
The preparation method of water-soluble feed additive alanine iron complex of the invention, it is characterized in that using following step
It is rapid: to choose alanine and ferrous nitrate in molar ratio for 1: 1-1.5；It is first that alanine is soluble in water, it is heated to 60-80 DEG C, is protected
Constant temperature is held, ferrous nitrate is then added and keeps stirring, reacts 0.5-1.0 hours；Then it is cooled to 25-35 DEG C, makes alanine iron
Crystallization is precipitated；Mother liquid recycling.
Alanine iron complex of the present invention is that alanine is ferrous.
The preparation method is that exploration of the inventor according to the practice of research and production for many years, sufficiently has studied alanine
The physicochemical properties of iron complex, found out a simple production process, high income, product quality be easy to control, cost
Lower preparation method.
Preparation method of the invention has the advantage that 1. are not added alkali, does not have to catalyst, in a water bath through being complexed；
2. first making alanine soluble in water, reaction temperature is controlled, ferrous nitrate is added, both accelerates reaction speed, in turn avoid
The oxidation of ferrous nitrate；3. after cooling, controlling certain temperature spot (solubility of alanine ferrous iron is minimum), tying product directly
Partial crystallization goes out.4. mother liquid recycling not only reduced costs, but also reduced the discharge of waste water, it is conducive to environmental protection.
Specific embodiment
Example 1
It chooses 0.12 mole of alanine to be dissolved in 500 milliliters of water, is heated to 68 DEG C or so, it is sub- that 0.13 molar nitric acid is added
Iron is kept stirring, and is reacted 0.8 hour.Then 25 DEG C or so are cooled to, alanine iron complex direct crystallization is precipitated.Through being centrifuged
It separates, dries, crushes, being packaged into finished product.Product yield is 64.86%, iron content 17.56%.
Example 2
300 milliliters of 1 mother liquor of example is taken, 0.1 mole of alanine is added, heating stirring is allowed to whole dissolutions, is heated to 75
DEG C or so, 0.11 molar nitric acid ferrous iron is added and keeps stirring, reacts 0.5 hour.Then 32 DEG C or so are cooled to, alanine iron is made
Complex compound direct crystallization is precipitated.It is centrifuged, dries, crushes, is packaged into finished product.Product yield is 90.19%, iron content
17.43%.
