| titleOfInvention | A kind of phosphonic acids laminarin iron and preparation method thereof |
| abstract | The present invention relates to a kind of phosphonic acids laminarin iron and preparation method thereof.The following steps are included: laminarin is mixed with aminoethylidenediphosphonate, thionyl chloride is added dropwise at a temperature of -7 DEG C -13 DEG C, the reaction was continued 1-3 hours after being added dropwise, and is then warmed to room temperature 10-14 hours naturally, obtains phosphonic acids laminarin then at rotary evaporation at 50-70 DEG C；Phosphonic acids laminarin is dissolved with distilled water, ironic citrate is added under the conditions of 50-60 DEG C of water bath with thermostatic control, and 20% sodium hydroxide solution is added dropwise and adjusts pH value of reaction system to 89；Continue to be stirred to react 3-5 hours after being added dropwise to complete；Centrifuging and taking supernatant obtains phosphonic acids laminarin iron after carrying out alcohol precipitation, centrifugation, washing, drying process to it.The present invention uses synthetic method easy to operate, synthesizes phosphate content and the higher phosphonic acids laminarin iron of iron content at a lower temperature, has unique advantage in actual application. |
