0 a substance that is formed by distilling a liquid
A number of special devices for vaporizing kerosene and the lighter distillates have been tried and used with some success.
Collect the distillate, mix with chloride of calcium or anhydrous sulphate of copper, and again distil.
Distillates or fuel oils and the crude oils are much the cheapest of the liquid fuels, and if used efficiently in internal-combustion engines would be by far the cheapest fuels available in many large districts.
The distillate is diluted with water, run off from any oily impurities which are separated, and re-distilled once or twice after treatment with quicklime.
The distillate of water and oil is warmed, and will separate into two layers, the upper one of which is oil, and the lower water.
The second distillate will show little, if any, ammonia in ordinary cases.
This residue in its turn is then subjected to distillation under reduced pressure to give both a vacuum distillate and a vacuum residue.
For example, for every litre of crude distillate burnt, 0.0033 tons of carbon dioxide is produced.
