摘要
Chitosan was N-permethylated by reaction with formaldehyde and sodium borohydride under controlled conditions (pH 4·0, 15°C, reaction times 12 and 8 h, respectively). The N-permethylated chitosan was reacted with methyl iodide at 35°C and N-trimethyl chitosan iodide with a quaternary nitrogen degree of 60% was obtained. This material may have uses as an antibiotic and an ion exchange material.
