experiment example 3

[0124] Experimental Example 3 The control of the first alkali addition of the polysaccharide-iron complex of the present invention

[0125] In production research engineering, the yield of polysaccharide-iron complex is sometimes high, sometimes low, and sometimes even the final product cannot be obtained. After a lot of experimental research, it was unexpectedly found that the control of the first addition of lye is a key link. If the addition is too fast or excessive, the polysaccharide-iron complex cannot be formed later. After a lot of experiments, it was found that 220-250 parts by weight (preferably 190-210 parts by weight, 244 parts by weight, 225 parts by weight) of 10%-20% aqueous sodium hydroxide solution was added to the reaction tank within 60-90 minutes During the process, the reaction temperature is controlled at 15-25°C. After the feeding is completed, the stirring is continued until the reaction is completed within the above range, and finally the yield of the ...

Abstract

The invention discloses a preparation process and a quality detection method of a polysaccharide-iron complex. The specific steps are: add the syrup solution in the reaction tank to stir, and cool; add the ferric chloride solution to stir, add the sodium hydroxide solution to generate a brownish red gel; add the precipitate obtained by adding the sodium hydroxide solution, add a precipitant to wash twice, Dried, that is polysaccharide iron complex. The preparation method of the present invention has few reaction steps, mild reaction conditions, good reproducibility, reliable process conditions, and no need for refrigeration equipment; no waste gas is generated during the reaction, which reduces the possibility of excessive pressure in the reaction tank in industrial production. Explosive hazard. The method for determining the content of the polysaccharide-iron complex has high accuracy, good precision, strong specificity and durability, meets the requirement of linearity, and is accurate, sensitive and simple.

Description

technical field [0001] The invention relates to a preparation process of a compound and a quality detection method thereof, in particular to a preparation process of a polysaccharide-iron compound and a quality detection method thereof. Background technique [0002] Anemia is a common disease, and its types can be roughly divided into iron deficiency anemia, hemolytic anemia, aplastic anemia and hemorrhagic anemia. The main causes of anemia are insufficient or impaired use of iron available to the body, and weakened bone marrow hematopoietic function, all of which can lead to decreased red blood cell production. [0003] Iron-deficiency anemia is one of the most common nutritional deficiency diseases in children in the world. It not only affects children's growth and development, but also affects immunity, brain function, and intellectual development. The prevalence of iron-deficiency anemia in children in my country is 57.6%. Mainly treated with iron. Iron-deficiency anemi...
