Solvent extraction is a process in which a substance can be separated from its matrix. The extraction of these active compounds needs appropriate extraction methods that consider the plant parts used as starting material, the solvent used, extraction time, particle size and the stirring during extraction [52, 53]. N-methyl-2-pyrrolidone is recovered from the raffinate and extract phases produced by its use in hydrocarbon extraction processes, particularly lube oil extraction, through the use of flash evaporation and/or distillation followed by gas stripping. Typically, organic solvents such as ether or benzene are used to shake aqueous solutions first. Here is how the extraction process works: As the microwave is turned on, the solvent molecules (mostly water) absorb the energy from microwaves and start moving. After extraction, the extract is collected and treated with lead acetate to precipitate tannins. The results of the extracts are either essential oils, absolutes, and other concretes.
