2. Dichloromethane - Wikipedia

   en.wikipedia.org/wiki/Dichloromethane

   Dichloromethane extract of Asparagopsis taxiformis, a seaweed fodder for cattle, has been found to reduce their methane emissions by 79%. [19] It has been used as the principal component of various paint and lacquer strippers, although its use is now restricted in the EU and many such products now use benzyl alcohol as a safer alternative.

3. Separatory funnel - Wikipedia

   en.wikipedia.org/wiki/Separatory_funnel

   To use a separating funnel, the two phases and the mixture to be separated in solution are added through the top with the stopcock at the bottom closed. The funnel is then closed and shaken gently by inverting the funnel multiple times; if the two solutions are mixed together too vigorously emulsions will form.

4. Work-up - Wikipedia

   en.wikipedia.org/wiki/Work-up

   The acyl chloride is added slowly to a solution of the amine and triethylamine in dichloromethane at 0 °C. The reaction is allowed to warm to room temperature and is stirred for 14 hours. The following manipulations are then performed on the crude reaction mixture (3) to isolate the desired product: [4]

5. Acid–base extraction - Wikipedia

   en.wikipedia.org/wiki/Acid–base_extraction

   Acid–base extraction is a subclass of liquid–liquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [ 2 ] and results in the product being largely free of acidic or basic impurities.

6. Liquid–liquid extraction - Wikipedia

   en.wikipedia.org/wiki/Liquid–liquid_extraction

   A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).

7. Piperine - Wikipedia

   en.wikipedia.org/wiki/Piperine

   Due to its poor solubility in water, piperine is typically extracted from black pepper by using organic solvents like dichloromethane. [5] The amount of piperine varies from 1–2% in long pepper, to 5–10% in commercial white and black peppers.
