| titleOfInvention | Lignins pesticide dispersing agent with high-carboxyl-content HMW and preparation method thereof |
| abstract | The invention discloses Lignins pesticide dispersing agent with high-carboxyl-content HMW and preparation method thereof.After lignin and catechol are well mixed by the preparation method, the concentrated sulfuric acid is added, room temperature is cooled to after reaction and drying is purified, phenolate lignin is obtained；Phenolate lignin and alkenyl succinic anhydride are placed in reactor, organic solvent and sodium hydrate solid, stirring is added；80~95 DEG C of reactions are warming up to, are filtered, washing obtains carboxylated lignin after drying；Carboxylated lignin is added to the water, the lower melt into aqueous solution of stirring, regulation pH value to 10~12 adds epoxychloropropane, and polycondensation reaction adjusts reaction solution pH to 6~7, obtains lignin pesticide dispersing agent.Dispersant weight average molecular weight obtained by the present invention is more than 15000, and carboxyl-content is 3.2~4.0mmol/g, it is adaptable to Multiple Pesticides wettable powder and water dispersible granules, with excellent dispersiveness, stability, wetability and heat storage performance. |
