| titleOfInvention | Maunfacturing method of high purity chitosan and chitosanoligosaccarid |
| abstract | The present invention is made of amino group by removing acetyl group from acetamide group located at C-2 position of chitosan, and using organic biodegradable and nontoxic natural polymer material to suppress and kill water purification, wastewater treatment and pathogenic bacteria Adsorption and hydrophilicity and chelate effect, water purification by biochemical treatment method is possible. In addition, chitosan and chitosan oligosaccharides, which are natural polymers, are cationic natural polymer polymers, which are used as flocculants to effectively aggregate high-purity raw water. The present invention is deacetylation degree 90% or more viscosity 10cps ~ 23cps, chitosan 2.0 to 7.0% solubilized in 0.5% to 5.0% solution of acetic acid and pH 4.0 ~ pH6.5, temperature 30 ℃ ~ 55 ℃, chitosanase 0.5 ~ After adding 5.5 units / kg and reacting for 10 to 16 hours, the low molecular weight chitosan oligosaccharide having a molecular weight of 5000 or less, deacetylation degree of 80% or more, viscosity of 200 cps to 400 cps, and chitosan are dissolved in a 0.5% to 5.0% solution of acetic acid so as to 1.0 to 3.0%. .0 ~ pH6.5, temperature 30 ℃ ~ 55 ℃, chitosanase 0.5 ~ 5.5unit / kg, reacted for 8 ~ 12 hours to produce high molecular weight chitosan oligosaccharides with molecular weight of 300,000 or less, and low molecular weight chitosan and high molecular weight chitosan. By mixing and considering the characteristics of different molecular weights, both water purification and aquatic ecosystems can be stabilized as eco-friendly water purification agents. |
