A piece of paper can purify the water in the gutter

In some parts of the world, it is not easy to find drinking water in places where public systems are missing. Drinking water and purifying water are really problems. A researcher named Theresa Dankovich invented a cheap, easy-to-use method to purify water.

At the core of this method is a filter paper, each of which is impregnated with a bacteria killing metal nanoparticle. The paper is put into a book called The Drinkable Book. Dankovich plans to explain this technology at the 250th International Exposition of the American Chemical Society and gives the results of his research in Africa and Bangladesh.

The metal particles used to impregnate the paper are silver, which can filter out a large portion of microorganisms, including bacteria and viruses. After testing the water in the gutter, after using this filter paper, 99.9% pure water can be obtained.

Dankovich said that part of the silver and copper on the filter paper will enter the drinking water, but the loss is very small, and it is less than the EPA and WHO standards for drinking water.


Industrial applications

Morpholine is a common additive, in ppm concentrations, for pH adjustment in both fossil fuel and nuclear power plant steam systems. Morpholine is used because its volatility is about the same as water, so once it is added to the water, its concentration becomes distributed rather evenly in both the water and steam phases. Its pH adjusting qualities then become distributed throughout the steam plant to providecorrosion protection. Morpholine is often used in conjunction with low concentrations of hydrazine orammonia to provide a comprehensive all-volatile treatment chemistry for corrosion protection for the steam systems of such plants. Morpholine decomposes reasonably slowly in the absence of oxygen even at the high temperatures and pressures in these steam systems.

Organic synthesis

Morpholine undergoes most chemical reactions typical for other secondary amines, though the presence of the ether oxygen withdraws electron density from the nitrogen, rendering it less nucleophilic (and less basic) than structurally similar secondary amines such as piperidine. For this reason, it forms a stable chloramine (CAS#23328-69-0).

It is commonly used to generate enamines.

Morpholine is widely used in organic synthesis. For example, it is a building block in the preparation of the antibiotic linezolid and the anticancer agent gefitinib 

Morpholine is used as a chemical emulsifier in the process of waxing fruit. Fruits make waxes naturally to protect against insects and fungal contamination, but this can be lost by means of the food processing companies when they clean the fruit. As a result, an extremely small amount of new wax is applied and morpholine is then added and used as an emulsifier to evenly coat a fruit with the wax.

In research and in industry, the low cost and polarity of morpholine lead to its common use as a solvent for chemical reactions.

As a component in fungicides

Morpholine derivatives used as agricultural fungicides in cereals are known as Ergosterol Biosynthesis Inhibitors.
