羧甲基纖維素鈉的合成機(jī)理
纖維素堿化為堿纖維素：
Cell-(OH)3+xNaOH = Cell-(OH)3-x(O-Na+)x+xH2O
氯乙酸轉(zhuǎn)化為氯乙酸鈉：
ClCH2COOH +NaOH = ClCH2COONa+H2O
堿纖維素和氯乙酸鈉轉(zhuǎn)化為：
Cell-(OH)3-x(O-Na+)x +nClCH2COONa = Cell-(OH)3-x (ONa) x-n(OCH2COO-Na+) n + nNaCl
經(jīng)過(guò)中和、洗滌：
Cell-(OH)3-x (ONa) x-n(OCH2COO-Na+) n+( x-n)CH3COOH = Cell-(OH)3-n(OCH2COO-Na+) n+( x-n)CH3COONa
