天然矿石蜡的精制研究

Study on the Refinement of Natural Ore Paraffin Waxes

对天然矿石蜡进行了脱树脂及氧化精制研究 ,探索国产矿石蜡能否通过精制后满足合成改性浅色蜡如O蜡、E蜡、OP蜡的使用要求。实验结果表明 ,该天然矿石蜡很难制成完全的乳白色蜡。研究了一种用浓H2 SO4+K2 Cr2 O7对其进行氧化精制的优化方法 。

The removal of resin in stone waxes from sands and refinement of resin removed (pure waxes) by oxidation have been done to explore the possibility of producing the modified O,E,OP ore paraffin waxes from the refined chinese ore paraffin waxes.The experimental results show that the waxes could not be completely bleached into colorless or bright waxes,but we can find a optical method of refining the waxes by K 2Cr 2O 7 and H 2SO 4. The major reasons why the stonewaxes could not be completely bleached to colorless have been discussed.
