Bioethanol – the raw material for the production of valuable chemical compounds

Abstract

The review analyzes the production of bioethanol from various biomass sources. The article considers the latest data on the production of bioethanol in various countries, including the importance of bioethanol produced in our country. The main raw materials for producing bioethanol are sugar cane, sugar beet, wheat, rice, cassava, barley, sweet sorghum, algae biomass. In the process of producing bioethanol, the main attention is paid to the nature of the raw material, the differences in its biochemical composition, and the cost of raw materials. The largest producers of bioethanol in the world are the United States and Brazil. In Brazil, bioethanol is produced from sugar cane, in the United States, the main raw material to produce biofuels is corn. In our country, bioethanol is obtained mainly from wheat.

 In addition, the review analyzes the catalytic transformation of bioethanol into valuable chemical compounds as acetaldehyde, 1,1-diethoxyethane, butanol from literature sources. Acetaldehyde obtained from bioethanol is an important feedstock to produce other chemicals such as acetic acid, acetic anhydride, etc. 1,1-Diethoxyethane, butanol can be used as solvents, octane-boosting additives to fuels. Butanol is also used in the synthesis of many organic compounds, such as butyl acetate, butylacrylate, etc. The conversion of bioethanol into value-added products is cost-effective and environmentally sound considering that bioethanol can be produced not only from agricultural products but also from various wastes containing sugar and starch.
