Abstract
The invention discloses a kind of preparation method of potassium dihydrogen citrate, comprise the following steps: citric acid and Tripotassium Citrate are prepared burden according to the ratio of 1:0.70 ~ 1:9, after batching, is placed on container for stirring; After stirring, add the pure water of 25% ~ 30% of material summation weight; After adding pure water, at least stir in not timing within an hour, sieved by work in-process after stirring, granulation after sieving, granulation post-drying obtains finished product.After present invention employs this method, method is simple, be easy to realize, and the quality product produced is high, and the product produced is used for the surfacing making other products, can improve surfacing quality of the prior art.
Description
Technical field
The present invention relates to a kind of preparation method of potassium dihydrogen citrate.
Background technology
Potassium dihydrogen citrate is the requisite that citric acid weighs when potassium is produced, and in prior art during production potassium dihydrogen citrate, owing to not knowing concrete proportioning, therefore uses C

2o is mixed with under random ratio, and complex process, the product prepared be unstable, easily turn to be yellow, and makes quality product not high.
Summary of the invention
The object of the invention is to solve the problem that the quality product of the potassium dihydrogen citrate adopting random ratio to be mixed with out in prior art is not high.
The technical solution used in the present invention is:
A preparation method for potassium dihydrogen citrate, comprises the following steps:
Citric acid and Tripotassium Citrate are prepared burden according to the ratio of 1:0.70 ~ 1:9, after batching, is placed on container for stirring;
After stirring, add the pure water of 25% ~ 30% of material summation weight;
After adding pure water, at least stir in not timing within an hour, sieved by work in-process after stirring, granulation after sieving, granulation post-drying obtains finished product.
As a further improvement on the present invention, preparation method comprises the following steps:
Citric acid and Tripotassium Citrate are prepared burden according to the ratio of 1:0.70, after batching, is placed on container for stirring;
After stirring, add the pure water of 25% of material summation weight;
After adding pure water, within 2 hours, not timing is stirred, and sieved by work in-process after stirring, granulation after sieving, granulation post-drying obtains finished product.
As a further improvement on the present invention, preparation method comprises the following steps:
Citric acid and Tripotassium Citrate are prepared burden according to the ratio of 1:0.88, after batching, is placed on container for stirring;
After stirring, add the pure water of 30% of material summation weight;
After adding pure water, within 2.5 hours, not timing is stirred, and sieved by work in-process after stirring, granulation after sieving, granulation post-drying obtains finished product.
As a further improvement on the present invention, preparation method comprises the following steps:
Citric acid and Tripotassium Citrate are prepared burden according to the ratio of 1:0.82, after batching, is placed on container for stirring;
After stirring, add the pure water of 27% of material summation weight;
After adding pure water, stir in not timing within an hour, sieved by work in-process after stirring, granulation after sieving, granulation post-drying is become.
The invention has the beneficial effects as follows: after present invention employs this method, method is simple, be easy to realize, the quality product produced is high, and the product produced is used for the surfacing making other products, can improve surfacing quality of the prior art.
