1·The high melting-point paraffin wax was prepared by taking slack wax as feed and MIBK as single solvent for deoiling.

用减三线蜡膏为原料，采用MIBK单一溶剂脱油新技术，进行蜡膏脱油制取高熔点石蜡研究。

2·The effects of the solvent ratio, the dilution solvent ratio and deoiling temperature on the slack wax deoiling were examined.

分别对溶剂比、稀释溶剂比和脱油温度进行了考察。

3·The paper introduced the process for low-melting of semi-refined wax made with slack wax from by-product in butanone-toluene dewaxing unit.

介绍了应用石蜡发汗工艺以酮苯脱蜡装置副产的蜡膏为原料生产低熔点半精炼石蜡的过程。

4·After using dewaxing aid, the filtration rate and the dewaxed oil yield were improved, the oil content in slack wax was decreased, and the dewaxed oil changed little in solidification point.

使用脱蜡助剂后，过滤速度、去蜡油收率提高，蜡膏含油量降低，去蜡油凝点变化不大。
