摘要
研究了风化煤、褐煤腐植酸（ＨＡ）及其氧解产物（ＮＨＡ）与卤硅烷的缩合反应。产物的组成分析、红外、ＤＴＡ、吸附性能和表面张力等测定结果表明，ＨＡ及ＮＨＡ同卤硅烷的反应活性与其羧基含量有较好的相关性，卤硅烷的反应活性民Ｒ＿ｎＳｉＣｌ＿４－ｎ＞Ｐｈ＿ｎＳｉＣｌ＿４－ｎ（苯基氯代硅烷）。硅烷化产物具有较好的热稳定性与表面活性。
The condensation polymerization of humic acid(HA)and nitro hunmic acid(NHA)from weathered coal and lignite with silicon haloganide was studied.The variation ofchemical composition, IR spectra,DTA,adsorption capacity,surface tension have been ob-served.The resuits show that reactive activity of HA and NHA depends on the content ofacidic functional groups and is mainly related to the content of-COOH in HA and NHA.The order of reactive activity of silicon haloganide is R_nSiCl-n>Ph_nSiCl_4-n. The productsof the reaction have good htermal stability and surface activity.
