Process for preparing alumina being suitable for layer chromatography |
摘要 |
The invention relates to a process for preparing alumina being suitable for layer chromatography. The alumina suitable for layer chromatography is prepared in accordance with the invention in such a manner that an aluminium trinydroxyde containing 34 to 37% by weight of bayerite, 3 to 5% by weight of pseudoboehmite and 60 to 62% by weight of amorphous aluminium trihydroxide is heated at 300 DEG C. to 400 DEG C. for 2 to 4 hours. The activated alumina thus produced is snow-white, has a large specific surface and its average grain size is within the range between 8 and 20 mu m. The product complies with the requirements of layer chromatographical technique.
