Fuel denatured

Second, sensors are often intended for a single use, or for usage over periods of one week or less, and enzymes are capable of excellent performance over these time scales, provided that they are maintained in a nfild environment at moderate temperature and with minimal physical stress. Stabilization of enzymes on conducting surfaces over longer periods of time presents a considerable challenge, since enzymes may be subject to denaturation or inactivation. In addition, the need to feed reactants to the biofuel cell means that convection and therefore viscous shear are often present in working fuel cells. Application of shear to a soft material such as a protein-based film can lead to accelerated degradation due to shear stress [Binyamin and Heller, 1999]. However, enzymes on surfaces have been demonstrated to be stable for several months (see below).

ASTM D-4806, Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use in Automotive Spark-Ignition Engines. 

The strength of alcohol commonly used in the US is 95% (190 proof), while 96% is used in Europe. For prepn of perfumes the 70% alcobol is used. TTie so-called absolute alcobol (200 proof) is at least 99% and its use is restricted. to analytical purposes or research. The so-called industrial alcohol is unfit to drink because it contains up to 5% methanol (wood alcohol) or benzene. Such alcohol is known as denatured and it is briefly described in Vol 3 of Encycl, p D63-R. Denatured alcohol is used as a solvent for expls, rocket fuels, rubbers, detergents, etc. Mixture of 1 part alcobol with 2 parts eth (described in Vol 5 of Encycl as Diethyl Ether) used as a solvent in dehydration of Pyrocellulose in manuf of single-base propint, such as described in Davis (Ref 2) and also on p C399 of Vol 3 of Encycl, under "Colloiding Agents and Colloidal Propellants ... 

Alternative Fuel Includes methanol, denatured ethanol and other alcohols, separately or in mixtures of 85% by volume or more with gasoline or other fuels, CNG, LNG, LPG, hydrogen, coal derived liquid fuels, fuels other than alcohols derived from biological materials, electricity, neat biodiesel, or any other fuel determined to be substantially not petroleum and yielding substantial energy security benefits and substantial environmental benefits. It is defined pursuant to the EPACT (Energy Policy Act of 1992), alternative fuels. 

To prepare, clean and dry a square, half-gallon milk carton. Pour in 4 cups of fuel and 2 tablespoons of denatured alcohol. Mix well. Add 2 1/2 cups of soap powder or 3 1/2 cups of soap flakes. Stir until it begins to thicken, approximately 15 minutes. Seal the carton with tape and let it sit for 2 days. The mixture will thicken into a firm buttery paste. Chill for an hour in the refrigerator, remove, and carefully peel off the milk carton. Cut the resulting block into 1-inch slabs and place them in individual sandwich bags. Double wrap to help contain the fumes. 

Diethyl ether is used in the production of rubber, plastics, paints, coatings, perfumes, and cosmetics. It is used as a solvent or extractant for fats, waxes, oils, resins, dyes, and alkaloids. It is also used as a fuel additive, alcohol denaturant, and as a medical anesthetic. 

Use Intermediate for n-butyl alcohol and 2-ethyl-hexyl alcohol, solvent, preparation of rubber accelerators, purification of lubricating oils, insecticides, tear gas, fuel-gas warning agent, organic synthesis, leather tanning, alcohol denaturant. 

See alcohol, denatured alcohol, industrial biomass. Note Ethanol from fermentation of biomass and hydrolysis of cellulose is a significant alternate energy source, especially as an automotive fuel. Its use in gasoline will continue to increase.

Ethyl alcohol is used in antifreeze products, and also as a fuel a solution of 70-85% of ethyl alcohol is commonly used as a disinfectant. It kills organisms by denaturing their proteins and dissolving their liquids and it is effective against most bacteria, fungi and many viruses though ineffective against bacterial spores. 

Alternative fuels such as grain alcohol were available. But, alcohol was more expensive at twice the price per gallon at the turn of the century. This did not include the federal excise tax placed on alcohol in 1862 to help reduce the Union s costs in the Civil War. By 1907, the tax was repealed. But, the process of denaturing alcohol, to make it undrinkable and enforce the sobriety of Americans, added to its price and gave gasoline the advantage. It also took more alcohol to produce the same amount of power than gas.
