| titleOfInvention | A kind of preparation method of cholesterol carboxymethyl chitosan derivative material and application |
| abstract | The present invention relates to a kind of bio-matrix Material Field, it is higher to solve synthesis price in prior art, can not natural degradation, there is no induction release function, there is no targeting and slow release, compatible little the problems such as, the present invention, propose a kind of preparation method of cholesterol carboxymethyl chitosan derivative material with application（1）In phthalic anhydride to shitosan C 2 NH 2 Under conditions of being protected, by carboxymethylation reaction is carried out to shitosan, synthesize O carboxymethyl chitosans,（2）By cholesterol and carboxymethyl chitosan C 6 On COOH carry out esterification, synthetic cholesterol carboxymethyl chitosan derivative material.Using the cholesterol carboxymethyl chitosan derivative material of the present invention; the nanometer environmental protection capsule sustained-release antibacterial pesticides new formulation with efficient, low-residual can be developed, the action of agricultural chemicals lasting period can be extended, agricultural pesticide amount of application, agricultural chemicals efficient utilization and environmental protection is reduced. |
