Glycerin is it made from pig?
To summarize the process, not directly. Glycerin is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Since glycerol forms the backbone of triglycerides, it is produced by saponification or transesterification. These processes are seen in soap-making and biodiesel production. Glycerol is a 10% by-product of biodiesel production. The process involves reacting vegetable oils or animal fats catalytically with a short-chain aliphatic alcohols (typically methanol or ethanol) to produce the fuel and glycerol. Hence glycerol is created by processing a variety of fats from both animals and vegetables and not from pigs alone.
What gas do human and animals breathe out?
We breath in air (left), breath out (right) which is approx;Nitrogen 79% -----------------------Nitrogen 79%Oxygen 20% -------------------------Oxygen 16%Argon 1%--------------------------------- Argon 1%Carbon dioxide 0.0384% ---carbon dioxide 4%We breath out air with a higher level of carbon dioxide and a lower level of oxygen; breathing also results in loss of water from the body, exhaled air has a relative humidity of 100% (with trace's of methanol and other organic compounds generated inside the body).humans breathe in oxygen and breathe out carbon dioxideCabon dioxide
Is methanol good solvent for extraction?
Methanol is a commonly used solvent for extraction due to its polar nature and ability to dissolve a wide range of compounds. However, it is important to consider the toxicity of methanol and ensure proper safety precautions are taken when using it for extractions. It is also important to be aware of the regulations and guidelines surrounding the use of methanol in extraction processes.
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.
How do you separate methanol from surfactants?
There are a number of methods that can be used to separate methanol from surfactants. The most effective method is extraction of the cationic surfactants by contracting the mixture with water.
Why you are using methanol and chloroform in lipid extraction?
Methanol is used to help dissolve lipids in the sample, while chloroform is used to extract lipids from the sample. The combination of these two solvents is commonly used in lipid extraction techniques to ensure efficient lipid recovery.
Is water heavier than methanol?
No, water is heavier than methanol. Water has a higher density compared to methanol, which means that for the same volume, water will weigh more than methanol.
Is methanol lighter than water?
Yes, methanol is lighter than water. Methanol has a lower density compared to water, which means it will float on top of water.
Why are methanol and ethanol not used for extractions?
Methanol and ethanol have low selectivity in extractions, meaning they can dissolve a variety of compounds, making it difficult to isolate target compounds. Additionally, they have high levels of toxicity, which can make them unsafe for use in extractions that involve human consumption or contact with biological materials. Lastly, methanol and ethanol can form azeotropes with water, making it challenging to completely remove them from the extracted solution.
What molecule has the highest boiling point methane chloromethane or methanol?
Methanol has the highest boiling point among methane, chloromethane, and methanol. This is because methanol has stronger intermolecular forces (hydrogen bonding) compared to methane (only dispersion forces) and chloromethane (dipole-dipole forces).
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
Is Methanol a nonelectrolyte?
Methanol is a nonelectrolyte because it is so weak it is not considered to be an electrolyte. Methanol is too weak to pass on electrons.
Is methanol burning a chemical change?
Yes, burning methanol is a chemical change because it involves a chemical reaction in which methanol reacts with oxygen to form carbon dioxide and water, releasing energy in the form of heat. This process is irreversible and results in the formation of new substances with different properties compared to the original methanol.
Why is methanol more acidic than water?
Methanol is more acidic than water because the methoxide ion formed after the loss of a proton from methanol is more stable than the hydroxide ion formed from water due to the higher electronegativity of oxygen compared to carbon. This stability makes it easier for methanol to donate a proton, thus exhibiting greater acidity.
