【摘要】：用十三氟辛基三甲氧基硅烷對SiO_2納米球(SN)表面進行功能化修飾,制得了耐腐蝕的超疏水SiO_2納米球(SNF)。將SN-F與90%濃硫酸在高速攪拌下混合,成功地制備了"干濃硫酸",即空氣包濃硫酸反相氣泡。探討了SN-F用量對形成"干濃硫酸"的影響,當SN-F的用量為濃硫酸質(zhì)量的5%時,"干濃硫酸"為粒徑100~200μm間均勻的球體。通過此方法制得的"干濃硫酸"形貌均勻、比表面積大,具有一定的機械強度,且其形貌及性質(zhì)在18個月后沒有改變,為濃硫酸的安全運輸、儲存、化學反應(yīng)等應(yīng)用提供了新的機會。
[Abstract]:The surface of SiO_2 nanospheres was functionalized with 13 fluorooctyl trimethoxy silane, and the anticorrosive superhydrophobic SiO_2 nanospheres were prepared. SN-F and 90% concentrated sulfuric acid were mixed at high speed. The "dry concentrated sulfuric acid", that is, the inverse bubble of concentrated sulfuric acid in air, was successfully prepared, and the effect of the amount of SN-F on the formation of "dry concentrated sulfuric acid" was discussed. When the amount of SN-F is 5% of the mass of concentrated sulfuric acid, "dry concentrated sulfuric acid" is a uniform sphere with a diameter of 100 渭 m or 200 渭 m. The "dry concentrated sulfuric acid" prepared by this method has a uniform morphology, a large specific surface area and a certain mechanical strength. The morphology and properties have not changed after 18 months, which provides a new opportunity for the safe transportation, storage and chemical reaction of concentrated sulfuric acid.
