Can ammonia dissolve in petroleum ether?
Thread Content
May I ask if ammonia can dissolve in petroleum ether?
It can dissolve because ammonia can form hydrogen bonds, and petroleum ether contains –O– bonds; it is readily soluble in water, ethanol, and diethyl ether. According to the principle of like dissolves like, it can dissolve in petroleum ether as well.
Petroleum ether is not an ether; it lacks O– bonds. Petroleum ether is a mixture of lower alkanes. The mixture of pentane and hexane has a boiling point range of 30–60°C ； A mixture of heptane and octane has a boiling point range of 90–120°C. They are mainly used as organic solvents. Naphtha is highly flammable and toxic; special care must be taken regarding safety when using and storing it.
The main components of petroleum ether are pentane and hexane. Ammonia should not be soluble in it
No, petroleum ether consists of alkanes.
Ammonia can dissolve in organic solvents, so it can dissolve in petroleum ether.
The range of organic solvents is too broad; it cannot be concluded that something is soluble in petroleum ether just because it is soluble in an organic solvent containing ammonia. For example, water is miscible with ethanol, but it is not miscible with gasoline, even though both ethanol and gasoline are organic solvents. Given the polarity of ammonia and the non-polarity of petroleum ether, it is unlikely that ammonia will dissolve in petroleum ether.
There are no absolutely immiscible substances! Petroleum ether has a relatively wide boiling range, and it is often divided into three grades: 30–60, 60–90, and 90–120. It is generally said that these three grades are insoluble in water, but in reality they are not 100% insoluble. According to the principle of like dissolves like, very little ammonia dissolves in petroleum ether!
Petroleum ether has an extremely low polarity, so ammonia should not be able to dissolve in it
