    INTRODUCTION OF ETHANOL Ethanol is one type of alcohol with two carbon attached on it in the chemical structure as in Fig 1.1. Ethanol is known as ethyl alcohol, ethyl hydrate and ethyl hydroxide with molecular formula C2H5OH. The general property of ethanol is a clear liquid and colorless. It comes with a pleasant odor. The molecular weight of ethanol is 46.07 g/mol. the density of the ethanol is 789 kg/m3 at 78.3 ⁰C. Ethanol is also fully miscible in water. The physical properties of ethanol can be referred

    to the commercial ethanol. For the physical properties of BIT and commercial ethanol, the ethanol showed different measurements in physical properties of BIT and commercial ethanol such as the density, smoke emission, and heat. Based on the given data, BIT and commercial ethanol are close to each other in terms of density and smoke emission. It can be assumed that there is no significant difference between the density and the smoke emission of BIT versus the commercial ethanol. While, on heat sample

    unfamiliar. The treatment, known as ethanol ablation, uses ethanol – a type of alcohol – to destroy crucial proteins and fatally empties the cancer cell. To help you better understand this, imagine tearing through a water balloon and draining it of water; well, that is akin to how ethanol destroys cancer cells. Today, ethanol ablation is used to treat liver cancer, and its 5-year survival rate is remarkably comparable to that of removal surgery. What makes ethanol ablation especially appealing is its

  • Corn Ethanol: Production Process

    831 Words  | 4 Pages

    Introduction Corn ethanol is made from corn which is utilized as biomass. The methods of making corn ethanol involve ethanol fermentation and distillation. Corn ethanol is primarily used as an oxygenate in gasoline to produce a low-level blend. To a lesser degree, it is used as fuel for E85 flex-fuel vehicles. This research paper will describe the process of producing corn ethanol. Production Process There are two primary kinds of corn ethanol generation: dry processing and wet processing. Each

    clean and renewable energy sources as well as their devices. Among these various energy systems, direct ethanol fuel cells (DEFCs) have been widely studied as ideal energy converters that convert chemical energy of ethanol directly to electrical energy2. In addition, ethanol is low cost and is in principle renewable when resourced from biomass. In comparison to pure hydrogen and methanol, ethanol possesses several important advantages:

    967 Words  | 4 Pages

    DETERMINATION OF PERCENTAGE ETHANOL IN BEVERAGES 1. Introduction to Gas Chromatography Gas chromatography is a very powerful separation technique for compounds that are reasonably volatile. The components of a sample partitions into two phases, the 1st of these phases is a immobile bed with a great surface area, and the other is a gas phase that permeates through the immobile bed. The sample is evaporated and passed by the mobile gas phase or the carrier gas through the column. Samples separates

    Abstract — This experiment was conducted to familiarize the students with the procedures regarding distillation—to be more precise, the separation of ethanol from an alcoholic beverage—using a distillation set-up consisting of boiling chips, a Bunsen burner, a condenser, a thermometer and several other materials. In the end, it was discovered that one may actually separate a homogeneous mixture, given that the components of said mixture differ in volatility and that they utilize a complete distillation

    of Yogurt and Ginger Ale Introduction Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. There are two types of fermentation namely ethanol fermentation and lactic acid fermentation. Ethanol fermentation occurs when pyruvate from glucose metabolism is broken down into alcohol and oxygen. In lactic acid fermentation, pyruvate molecules are fermented into lactic acid (Helmenstine, 2014). Examples of fermented products
