A refined method to extract volatile substances are substances which become constant evaporation is difficult. Simple distillation is used to separate a chemical substance pure single . substances with different boiling point
How is the distillation of the volatile. , which is mixed with volatile hard. been distilled to the isolation of a pure substance once. has compounds that have boiling points well. ranging from 80 ° C to
A method of refining extract volatile , which mixed with the volatile difficult this simple distillation. the separation into pure once substance with different boiling points since 80 degrees Celsius degree .
