摘要

基于制浆黑液自身的碱性环境，实现了羧甲基木质素（CML）的原位合成。与传统工艺相比，该方法避免了外加碱的使用，简化了生产流程，并大幅降低了生产成本。重点考察了反应条件对羧甲基木质素的转化率和羧基含量的影响，并探讨了pH、溶液离子强度等因素对比浓粘度、粒径及分散性等性能的调控作用。结果表明，反应温度为70 ℃，物料比例为1:1时，羧甲基木质素的转化率可达86.21%，羧基含量为2.185 mmol/g。羧甲基木质素对二氧化硅悬浮液分散结果显示，使用羧基含量为2.185 mmol/g的羧甲基木质素，在pH=7的二氧化硅悬浮液中稳定性指数降至1.02，具有良好的分散稳定性能。通过研究溶液浓度、pH及离子强度对羧甲基木质素分子电离、链构象及聚集行为的影响，构建了其在水中的聚集模型与机制。

Abstract

This study realized the in situ synthesis of carboxymethyl lignin (CML) based on the inherent alkaline environment of black liquor. Compared with conventional methods

this approach avoids the addition of external alkali

simplifies the production process

and significantly reduces production costs. The effects of reaction conditions on the conversion rate and carboxyl content of CML were systematically investigated

and the influence of factors such as pH and solution ionic strength on intrinsic viscosity

particle size

and dispersibility was further explored. The results showed that under a reaction temperature of 70 ℃ and a material ratio of 1:1

the conversion rate of CML reached 86.21%

with a carboxyl content of 2.185 mmol/g. The dispersibility evaluation using a silica suspension indicated that CML with a carboxyl content of 2.185 mmol/g exhibited good stability at pH 7

with the stability index decreasing to 1.02. Furthermore

the effects of solution concentration

and ionic strength on the molecular ionization

chain conformation

and aggregation behavior of CML were investigated

and a model describing its aggregation mechanism in aqueous solution was constructed.
