Principle

Remove paraffins from lubricating oil by extraction.The lubricating oil fraction must be prepared from petroleum by vacuum distillation. The lubricating oil offered by mineral oil companies is already freed from paraffin (wax), but lubricating oil containing paraffin can also be obtained from them.

Learning objectives

  • Unpurified lubricating oil contains long-chain paraffins which greatly reduce the lubricating effect in the cold.
  • These can be removed from lubricating oil by extraction with a solvent which dissolves oils and subsequent precipitation from the solvent.

Benefits

  • Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
  • Experiment is part of a complete solution set with experiments for the topic Organic Chemistry matched with international curriculum: all topics are covered
