Denatured alcohol.Methylated spirits is a mixture of roughly 95% methanol and 5% ethanol.
Under typical distillation conditions, ethanol can only be purified to 95% with 5% water remaining. There are additional techniques that can be used to remove the remaining water to make it anhydrous (no water). Do not confuse 95% alcohol with 95% denatured alcohol. In denatured alcohol the remaining 5% is composed of other alcohol impurities like methanol, propanol, and butanol, to name a few.
as we know benezene is a volatile liquid and toluene is a non volatile liquid so when we will keep that in room temperature benezene will get evaporated and we will trap those vapours so benezene is seprated
Methyl anthranilate can be synthesized by the reaction of aniline with excess methanol in the presence of a catalyst, such as hydrochloric acid. The reaction proceeds through an intermediate step to form the desired product. Purification of the crude product is typically done through distillation or recrystallization.
Dichloromethane (DCM), or methylene chloride is an organic solvent with a very low vapor pressure. Therefore, to dry it one can simply leave it out at room temperature and it will quickly evaporate.
Redistilling moonshine can concentrate methanol, particularly if the initial distillation did not separate it effectively. Methanol is produced during fermentation from pectin-rich materials and can be present in the distillate. If the distillation process is not carefully managed, harmful levels of methanol can accumulate, posing serious health risks. Therefore, proper distillation techniques are essential to minimize methanol content in any distilled spirits.
You can separate a mixture of acetone and methanol through fractional distillation. Both compounds have different boiling points (acetone: 56°C, methanol: 65°C) allowing for separation based on their boiling points. By heating the mixture and collecting the vapors at their respective boiling points, you can separate acetone and methanol into individual fractions.
One can test alcohol for methanol content by using a simple distillation process to separate the methanol from the alcohol. The methanol will evaporate at a lower temperature than the alcohol, allowing for its detection. Additionally, specialized testing kits are available that can detect the presence of methanol in alcohol.
Methanol was discovered by distilling boxwood (also known as the wood of the box tree) by John Hevelius in 1661. He called it "spirit of box." Later, methanol was also produced by the destructive distillation of wood.

assuming it's trace ammonia in lots of methanol, you can probably just heat the methanol to boiling and that should get rid of all the ammonia. molecular sieves (size 3 angstroms) would also probably work. if it's more than a trace amount, you can go for distillation.

This type of mixture is distilled by extractive distillation method. First, methanoic mixture is separated by feeding the required rate of water in the extractor with the counter-current of these two liquids. Later on GC is done for methanol content in the organic layer and if it comes below the required level, it is taken for rectificaton in the column.

You can separate a mixture of methanol and ethyl acetate by using fractional distillation. Since they have different boiling points (methanol: 64.7°C, ethyl acetate: 77.1°C), you can heat the mixture to a temperature between the two boiling points to selectively vaporize and collect each component.

Ethanol can be separated from a fermented mixture through a process called distillation. Distillation involves heating the mixture to vaporize the ethanol, which is then cooled and condensed back into liquid form. This allows for the separation of ethanol from other components in the mixture.
