What are types of solvents for plant extraction?
Common solvents used for plant extraction include water, ethanol, methanol, and hexane. Each solvent has specific properties that make it suitable for extracting different types of compounds from plants. It is important to choose a solvent that is safe, effective, and appropriate for the desired extraction outcome.
Is a significant amount of fat carried away with evaporated petroleum ether?
Yes, a significant amount of fat can be carried away with evaporated petroleum ether, which is commonly used as a solvent for extracting fats from samples. However, it is important to note that not all fats may be completely extracted and some residue may remain. Proper extraction techniques and solvent evaporation processes are essential to ensure efficient fat extraction.
Why are we using a mixture of ether and hexanes instead of using only ether or only hexanes?
Using a mixture of ether and hexanes allows for a wider range of solubility and better separation of compounds compared to using only ether or only hexanes. This combination provides a more versatile solvent system for various types of compounds in a chemical reaction or extraction process.
What is the best solvent for methyl benzoate?
The best solvent for methyl benzoate is typically a non-polar solvent such as diethyl ether or dichloromethane. These solvents are effective in dissolving methyl benzoate due to its non-polar nature and facilitate its extraction and purification processes.
Why is diethyl ether a food solvent for fats?
Because it's very good at dissolving things. Diethyl ether is polar. The center has a slight negative charge while the arms have a slight positive charge. Also hydrogen bonding can occur with the oxygen on diethyl ether.
Why can't alcohol be substituted for ether as an extraction solvent?
Alcohol is more polar and less volatile than ether, which can result in lower extraction efficiency and longer extraction times. Additionally, alcohol can form azeotropes with water that can complicate the extraction process. Ether is also considered safer due to its lower flammability compared to alcohol.

How is extraction related to chromatography?
Both are techniques of analytical chemistry and use a solvent.
How do you extract pigments?
hot water extraction , aqueous extraction, solvent extraction
Does NaCl dissolve in petroleum ether?
It is not soluble.
What are the adavantages of using ether as an extraction solvent?
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).

What separation techniques do dry cleaners use?
Dry cleaners use a variety of separation techniques such as solvent extraction, distillation, and filtration to separate dirt, oils, and stains from clothing. Solvent extraction involves dissolving contaminants in a solvent, distillation separates the solvent from the contaminants, and filtration removes any remaining solid particles.
