In modern day‚ man does not truly think about how much the earth means to life. On the contrary‚ humans aspire to cease Mother Nature’s beauty with the replacement of modern day cities made up of synthetic nature.

aqueous solution of formaldehyde is called formalin. The commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen
