WebJan 7, 2024 · Hydroxypropyltrimethyl ammonium chloride chitosan (HACC) and hydroxypropyltrimethyl ammonium chloride fully deacetylated chitosan (De-HACC) were synthesized with various degrees of substitution by altering the ratio of chitosan to glycidyl trimethyl-ammonium chloride (GTMAC). The effects of the quaternary ammonium … WebFeb 15, 2024 · The degree of quaternization (DQ) of chitosan was calculated by measuring the content of Cl − ions of the quaternized chitosan via conductometric titration with AgNO 3. DQ is dependent on the reaction time, reaction temperature, and the molar ratio of GTMAC to the amino groups on chitosan (Ahmed & Mondal, 2024). In this study, …
