For extraction of organic solvents generally diethylether is used because organic substances are generally soluble in ether and ether has got a low boiling point making its removal after the extraction very easy.
it can be flammable and explosive in some cases
Plants material contains Organic compounds along with salts and water, some organic compounds are polar and soluble in ethyl alcohol or ethyl acetate but some are non polar and soluble in ether or hexane, so two types of solvents may be used for plants extraction, the best way is to use non polar solvent first and extract the non polar compounds then use the polar solvent and extract the polar compounds.
conclusion for extraction of bitumen
HNO3= nitric acid
Ether
ether
No, alcohol is a polar solvent and extracts only polar components while ether is used to extract the non polar constituents.

Both are techniques of analytical chemistry and use a solvent.
hot water extraction , aqueous extraction, solvent extraction

It is not soluble.
The major disadvantage of using ether as an extracting solvent is that it is very flammable. It also oxidizes into an explosive in some cases, is an anesthetic, and is very vapor dense (meaning it will fall to the floor and move around there).
By solvent extraction with water. By fractional distillation.
