Ethanol

Ethanol, also known as alcohol or ethyl alcohol, is a volatile, flammable, and colorless liquid. Ethanol is characterized by a slight odor. It is simple alcohol with C 2H 6O has the chemical formulae. Ethanol is produced in processes like hydration of ethylene and during the fermentation of yeast. Ethanol is also found in overripe fruits. Uses of Ethanol Ethanol is an essential ingredient in many products and alcoholic drinks. However, the usage of Ethanol is limited as too much of Ethanol in the bloodstream may have adverse side effects on human health. For example, excessive Ethanol in the bloodstream may cause impairment of vision or may also cause death. Ethanol-related industries and products depend on it as a principal ingredient. Some of the uses of Ethanol are discussed below; 1. Alcoholic industries Ethanol is the main ingredient in the making of alcoholic drinks that are consumed for recreational purposes. It is, therefore, an important solvent in the alcohol-making industries. Ethanol contains psychoactive properties that tend to affect mental processes. These properties help to create a euphoria state to consumers hence relieving stress and anxiety. 2. Making food additives In the process of making food additives, Ethanol plays a vital role in distributing the color pigments. As an odor solvent, it also improves the flavor of the food color. Vanilla, which is commonly used to flavor beverages and foods, is made using Ethanol. A solution of water and Ethanol is ...

President Joe Biden's plan to reduce the price of gas Biden made his announcement Tuesday during a trip to Iowa, where corn — and ethanol — are crucial to the state economy. He said the Environmental Protection Agency would issue an emergency waiver from the Clean Air Act that will permit the sale of gasoline that is 15 percent ethanol, 5 percent more than the typical blend, from June 1 to Sept. 15. The change will lower gas prices by about 10 cents a gallon at the 2,300 gas stations equipped to pump it, the Biden administration says. To environmentalists, that's a small benefit compared to the damage the decision could do to efforts to reduce the country's carbon emissions. “What the president is doing is the definition of short-term thinking,” said Carroll Muffett, president and CEO of the Center for International Environmental Law. “The goal here shouldn’t be to bring gas prices down by 10 cents in the near term by increasing emissions that will endanger large parts of the population.” Although ethanol was embraced more than a decade ago as a renewable fuel, its green reputation has eroded. Scientists have found evidence that increased corn production for ethanol could increase greenhouse gas emissions; a study published in February said ethanol The reason Biden needs an emergency waiver is that the summertime use of gas with 15 percent ethanol, known as E15, is known to increase smog. Senior Biden administration officials have told reporters that the EPA's own analysis...

The production of ethanol from starch or sugar-based crops is among man’s earliest ventures into value-added agriculture-based processing. Henry Ford and Alexander Graham Bell were among the first to recognize that the plentiful sugars found in plants could be easily and inexpensively converted into clean-burning, renewable alcohol fuels. While the concept is the same today as it was then, the ethanol industry has come a long way since those days. Today, sophisticated Over 90 percent of the grain ethanol produced today comes from the dry milling process, with the remaining coming from wet mills. The main difference between the two is in the initial treatment of the grain. Dry Mill Ethanol Process In dry milling, the entire grain kernel is first ground into “meal,” then slurried with water to form a “mash.” Enzymes are added to the mash to convert starch to sugar. The mash is cooked, then cooled and transferred to fermenters. Yeast is added and the conversion of sugar to alcohol begins. After fermentation, the resulting “beer” is separated from the remaining “stillage.” The ethanol is then distilled and dehydrated, then blended with about 2%denaturant (such as gasoline)to render it undrinkable. It is then ready for shipment. The stillage is sent through a centrifuge that separates the solids from the solubles. These co-products eventually become distillers grains, as well as corn distillers oil. For more information on co-products and current production, visit our Wet Mill ...

Ethanol Facts - July 2022 Ethanol and Marine Engines July 2020 Ethanol Opens the Door July 2020 Small Engine Ethanol April 2019 Winterization Infographic Thanksgiving Infographic Today, nearly every gallon of gasoline in the U.S. contains a minimum of 10%ethanol derived from corn. Renewable fuels, such as corn ethanol, are an immediate climate change solution. As a low-carbon, clean energy source and an affordable, homegrown fuel, ethanol serves as a critical pathway for agriculture and rural America to contribute to a sustainable future. U.S. corn farmers believe so strongly in the case for higher blends of ethanol, because of corn ethanol’s ability to improve engine performance and reduce environmental impacts, all at a lower cost to consumers. Corn farmers work tirelessly to ensure consumers have a future choice at the fuel pump that delivers all the benefits possible through fuels blended with higher volumes of ethanol. Whether it’s backing the market access provided by the Renewable Fuel Standard (RFS)or expanding the marketplace with higher blends of ethanol, like E15, the National Corn Growers Association (NCGA)is working for America’s corn farmers to increase ethanol use. Each year, roughly 30%of field corn goes into fuel ethanol. Ethanol is the second-largest customer for U.S. corn. Corn ethanol is uniquely positioned to play a l...

Want to know more about ethanol grades commonly used in the lab? You already know that ethanol is super useful. It’s great for killing bugs, setting things on fire, and forcing nucleic acids out of solution. But not all ethanol is created equal, and not all kinds of ethanol are suitable for every task. To help you make sense of your flammables cabinet, here’s the rundown on the ethanol grades typically used in molecular biology, as well as some important rules for how to use them correctly. 3 Ethanol Grades Used in Molecular Biology Ethanol has a number of uses in microbiology. It is used in the purification and precipitation of biomolecules, in staining and restaining specimens in histology, in dehydrating tissues before embedding, and in disinfection. There are three grades of ethanol commonly used in the lab. 1) 95% (95.6%) Ethanol This is the highest concentration of ethanol you can get by distillation because 95.6% ethanol is an azeotrope, which means the vapor state has the same ethanol-to-water ratio as the liquid state. 2) Absolute (99–100%) Ethanol Some procedures that are sensitive to the presence of water require absolute ethanol. A common method to produce ethanol with a higher concentration than 95% is to use additives that disrupt the azeotrope composition and allow further distillation. For this reason, absolute ethanol sometimes contains trace amounts of these additives (such as benzene). Absolute ethanol is hygroscopic (it attracts water), so don’t expect ...
