Abstract: |
|||
| The present invention relates to a production process of chemical raw material-phytic acid by use of precipitation method. The production time of the existent common-used calciphytin productive line is reduced by 25%, its recovery rate is raised by 1-4%, the benefit can be increased by 30-50%, and it can eliminate a great number of contaminated waste waters and waste slags produced in the existent technological production. Its product quality is stable. | |||
