| Abstract: | 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. |
