摘要
研究了由氯乙酸和氯乙酸异丙酯为醚化剂制备羧甲基纤维素钠（ Ｃ Ｍ Ｃ Ｎａ）的工艺条件，讨论了在制备过程中的一些影响因素，找到了最佳制备工艺条件⒚用本工艺获得的产品，其取代度（ Ｄ Ｓ）可在 ０．７３８
The preparation of soudium carboxymethyl cellulose (CMC Na) from chloroacetic acid and iso propyl chloroacetate was studied.Some factors influencing on preparing process were discussed.The optimum technological conditions of the preparation of CMC Na were obtained.With this process,the degree of substitution (D.S) is above 0.738.
