Laboratory Soxhlet extraction at the boiling pint of various solvents were carried out. Of the solvents tried, a mixture of benzene and ethanol (50:50) was found to be the best. All crude extracts were black in colour. The effect of particle size was also investigated. The yields of crude extract were 0.9-4.8 per cent (Li lignite), 0.64-3.00 per cent (Mae Mo lignite), and 0.88-3.50 per cent (Krabi lignite). The yields of crude wax were very low, and therefore only the crude was from Li Lignite was refined and bleached. Authors.
