Is methanol a good solvent to use in paper chromatography?
Methanol is a commonly used solvent in paper chromatography because of its polarity and ability to dissolve a wide range of compounds. It is especially good for separating polar compounds. However, caution should be taken as methanol is also toxic and flammable.
How do you extract microbial pigments?
hot water extraction , aqueous extraction, solvent extraction
What are the three properties that a compound must possess in order for it to function well as an extraction solvent?
- the solvent must be miscible with the organic solute and not miscible with water- also any chemical reaction is permitted- higher yield of extraction- easy and complete recovery of the solvent
Why methanol is a good solvent for uv and not fof ir r?
Methanol is a good solvent for UV spectroscopy because it has a wide transparent region in the UV spectrum, allowing it to effectively dissolve various solutes without interfering with the UV absorption measurements. However, it is not suitable for infrared (IR) spectroscopy since methanol has strong IR absorbance due to its O-H and C-H bonds, which can obscure the spectral features of the analytes being studied. This characteristic makes methanol useful for UV analysis but problematic for IR applications.
Is solvent extraction extraction a type of chromatography?
Solvent extraction is not a type of chromatography. Solvent extraction involves the separation of compounds based on their solubility in different solvents, while chromatography separates compounds based on their interactions with a stationary phase and a mobile phase.
Would methanol be a better or poorer solvent for extraction of cholesterol from egg yolk compared to 2-propanol?
The solubility of cholesterol in methanol is 0.014. 2-propanol would be a better solvent than methanol for the extraction of cholesterol from egg yolk.
What is the role of methanol in the extraction of chlorophyll?
Methanol is commonly used as a solvent in the extraction of chlorophyll because it is highly polar and can effectively dissolve chlorophyll from plant material. Additionally, methanol helps to break down cell walls and release chlorophyll into the solvent, making it easier to extract. After extraction, methanol can be evaporated to leave the chlorophyll behind.

What is a good solvent to extract Rhodamine B out of a highliter?
methanol
How curcumin is extracted from termeric powder?
Curcumin is extracted from turmeric powder through a process called solvent extraction. In this method, turmeric powder is mixed with a solvent, typically ethanol or methanol, which dissolves the curcumin. The mixture is then filtered to remove the solid residue, and the solvent is evaporated to yield concentrated curcumin. Alternative methods include supercritical fluid extraction and cold pressing, but solvent extraction remains the most common approach.
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
What is the solubility of hexane in methanol?
The solubility of hexane in methanol is low because hexane is a nonpolar molecule and methanol is a polar solvent. This means that hexane does not mix well with methanol.

Which temperature for methanol to use in soxhlet extractor?
It's not entirely clear what you're asking about, as different portions of the apparatus will be at different temperatures, but at normal atmospheric pressure methanol boils at a bit under 65 degrees Celcius.
