| titleOfInvention | A kind of phosphate mineral inhibitor and preparation method thereof and purposes |
| abstract | The present invention is a kind of N- naphthalene-alpha-azyl aryl phosphonic acids, and general molecular formula is (I).The invention also discloses N- naphthalene-alpha-azyl aryl phosphonic acids preparation methods and purposes.Preparation method is the N- naphthalene-alpha-azyl aryl phosphonic acids, and by naphthalidine, aromatic aldehyde and phosphorous acid, mannich reaction is prepared in acid condition.Its raw material naphthalidine, aromatic aldehyde, phosphorous acid, concentrated hydrochloric acid molar ratio be 1:1~1.4:1~1.4:0.9~1.1.100 ~ 150 DEG C of reaction temperature, the reaction time is 1 ~ 3 hour.N- naphthalene-alpha-azyl aryl phosphonic acids synthesis technology of the present invention is simple, and the reaction time is short, and the compound of synthesis has stronger inhibiting effect to phosphate mineral, can use under neutral or weak basic condition. |
