| titleOfInvention | A kind of preparation method of organic selenium-EDTA chelating selenium |
| abstract | The invention discloses a kind of preparation methods of organic selenium-EDTA chelating selenium, weigh EDTA raw material using assay balance, are that raw material prepares organic selenium-EDTA chelating selenium using EDTA and selenium dioxide, solve the problems, such as that inorganic selenium is not suitable for being absorbed by humans and animals；The reaction temperature of EDTA and selenium dioxide is 60-70 DEG C, improve organic selenium-EDTA chelating selenium reaction generating rate, the reaction time of EDTA and selenium dioxide is 1-2h, organic selenium-EDTA chelating selenium the appearance color for ensuring to prepare is white powder article, and yield is improved, thickening temperature is 85 DEG C, and is stirred in concentration process, the organic selenium too high or too low for temperature to preparation-EDTA chelating selenium is avoided to impact, while can be improved thickening efficiency. |
