Metal tin is mainly used in the manufacture of alloys. Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment. Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.

Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices. The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst. Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.
