What is the basic difference between cleavanger apparatus and soxhlet apparatus used in extraction process?
Clevanger apparatus usually use to determine essential volatile oil from flowers, leaves while soxhlet apparatus use for the extraction of a lipid from a solid material like plant seeds. Phuong.
What current disadvantages exist to using gas hydrates as a form of energey?
Some current disadvantages of using gas hydrates as an energy source include high production costs, challenges in extraction due to their formation in remote and deep-sea locations, technical difficulties in harvesting and processing, and environmental concerns related to the release of methane, a potent greenhouse gas, during extraction.
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.
Why hexane is used as solvent in soxhlate apparatus?
Hexane is used because it is relatively unreactive. Actually, any solvent that is unreactive can be used. However, the general criteria to be employed in choosing a solvent are 1) its solubility/polarity to the mixture/solute, 2) its boiling point is lower than the solute/analyte and 3) it is unreactive.
Could sodium chloride and potassium nitrate be separated using extraction?
No, sodium chloride and potassium nitrate cannot be separated using extraction because both compounds are soluble in water. Extraction relies on the difference in solubility of compounds in different solvents to separate them. Since both compounds are soluble in water, they cannot be separated using extraction.

Is soxhlet extraction a good method in extracting and isolating nicotine from tobacco leaves?
Yes. Soxhlet extraction recycles the solvent so it passes through the sample in a lot of cycles so you can obtain a colored solvent solution in the end. This coloring is caused by the tobacco.
What is successive extraction?
Successive extraction of any plant part involves sequential extraction ( e.g. employing soxhlet apparatus or maceration) using solvents with increasing polarity. Following each extraction, the marc (refuse matter that remains after extract has been filtered) will be dried before being extracted using solvent with higher polarity. For example, the following solvents can be used in successive order (lower to higher polarity): petroleum ether then chloroform then ethyl acetate, then methanol.
What are the most important types of extraction process in pharmacognosy?
The most important types of extraction processes in pharmacognosy are maceration, percolation, Soxhlet extraction, and steam distillation. Maceration involves soaking the plant material in a solvent to extract the desired compounds. Percolation uses gravity to move the solvent through a column of plant material. Soxhlet extraction continuously cycles the solvent through the plant material. Steam distillation utilizes steam to extract essential oils from plant material.
What is soxhalation?
Soxhalation refers to the use of a soxhlet extractor. A soxhlet extractor is a piece of laboratory apparatus designed for the extraction of a lipid from a solid material.
What is proximate analysis of protein?
proximate analysis of fat can be done by using soxhlet apparatus
When was Franz von Soxhlet born?
Franz von Soxhlet was born in 1848.
When did Franz von Soxhlet die?
Franz von Soxhlet died in 1926.
What are Methods to calculate fat percentage in food?
Soxhlet extraction is the usual method; this doesn't require you to "calculate" anything, except to the extent that "(weight of fat/weight of original sample) * 100" is a calculation.
What are the advantages and disadvantages of solvent extraction?
The advantages are: - Goldfish requires less solvent than Soxhlet (solvent in Soxhlet has to reach the siphon level). - Goldfish is quicker because the sample is constantly in contact with the solvent.

What are the advantages and disadvantages of using a blade grinder for espresso preparation?
Advantages of using a blade grinder for espresso preparation include affordability and ease of use. However, disadvantages include inconsistent grind size, which can lead to uneven extraction and affect the quality of the espresso.
