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.

What you can learn about


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.
