Pure glycerin is a colorless sweet, and sticky liquid. It is a kind of triatomic alcohols , which has the general chemical properties of triatomic alcohols and can be involved in many chemical reactions to generate various derivatives. Due to its special physical and chemical properties, glycerol is widely used as a chemical materials for the manufacture of synthetic resins, plastics, paints, nitroglycerin, oils and beeswax, etc. It is also used in industries like the pharmaceutical, spices, cosmetics, and sanitary product.
It is used to produce ECH, modified alkyd resin and phenolic resin in chemical industry, used to make lubricants in the pharmaceutical industry, used as sweeteners, humectants, moisture absorbent for tobacco in the food industry, used as the raw material of nitroglycerin, & the antifreeze of aircraft and automobile fuel in the national defense industry, used for toothpaste and flavor production in the daily chemical industry. Furthermore, glycerol is widely used in papermaking, leather, cellophane, and textile industry, as well.
Significance of glycerol exploitation and utilization
With the rapid development of China’s economy, China’s oil and energy supply will keep replying on imports for a long time because of our extremely limited oil reserves. Moreover, scientists will also make unremitting efforts to the research and development of the alternative new energy sources. As a renewable new energy, biodiesel has a very broad development prospect, and its market competitiveness is being improved. At present, the main problem of biodiesel is the high cost. Researchers have started to solve this problem from raw materials and catalysts, but haven’t found a very ideal solution now. Experts and researchers are working to reduce the production cost of biodiesel from various aspects, including selecting cheap raw materials to prepare biodiesel, optimizing production process, reducing unnecessary production links and unnecessary consumption. At the same time, the production cost of biodiesel can be reduced by improving the comprehensive utilization rate of the by-product glycerol and increasing the added value of the product, and Improve the economic efficiency of biodiesel production.
Although people are actively researching and producing biodiesel, the research and development of its by-product glycerol is far from enough. A large amount of by-product glycerol has been mixed with feed to feed pigs. If a large amount of by-product glycerol was not used rationally, it would not only waste resources, but also possibly pollute the environment. So, from the perspective of research by product glycerol, the development of high-purity glycerin and various glycerin products can reduce the cost of biodiesel, and also reduce the government subsidies on biodiesel production. Furthermore, it can also relieve the pressure on the import of high purity glycerin and important pharmaceutical and chemical products. Its development momentum is irresistible, and can obviously promote our country’s economic development.
