The results indicated that extraction yield and product purity of OPC were high when broken grape-seed and dry grape-seed shell degreased by mineral ether were used as raw material, mixture of acetic ether and water was used as extracting agent. 结果表明,以粉碎的葡萄籽、石油醚脱脂干燥后的葡萄籽壳为原料,乙酸乙酯+水为提取剂所得提取产物纯度高,提取率可达0.4%~o。
As a large agricultural country with plenty of coal mines and other mineral resources, China can be benefited greatly from application of alternative fuels such as alcohol ether fuels. 中国是农业大国,煤炭等矿物资源储备丰富,这为醇醚等代用燃料的应用提供了前提。
