Medium advice for cars fueled with methanol and ethanol "We need stricter automotive exhaust gas regulation ... Let's add MTBE to fuel - this will reduce pollution ... Contamination It will not be so bad ... People have long recognized the gasoline problems we are using now. We tried various methods from the development of emission regulations to the addition of additives to gasoline (later found in groundwater), and the people are driven out of the road. However, as the population increases more and more cars are driving on the road, people will not stop driving. Additives can cause problems
Ethanol is often confused with methanol. These two alcohols have significantly different properties. Unlike ethanol, methanol is very toxic. Ethanol provides better water resistance and better fuel system compatibility and contains less oxygen than methanol. Although methanol causes a significant increase in volatility, ethanol only causes a small increase, usually it is lower than the gasoline increase between batches in the market area. Ethanol,% by volume. Methanol 92.1, volume% max 0.5 solvent wash gel 0 mg / 100 ml max. Water content, maximum volume%, denaturant content,% by volume. 96 volume% maximum 0 inorganic chloride content, mass 10 (8) ppm (mg / L), maximum copper content, mg / kg, maximum 0.1 acidity (CH 3 COCH acetate), 0.007 (56) mg / L), maximum pHe 5 - 0, sulfur, mass ppm, maximum 30. Sulfate, mass ppm, maximum 4 appearance is obviously not a suspension or precipitation
There are various analogues in ethanol, many of which have similar effects and effects. Methanol (methanol) and isopropanol are toxic and dangerous for human consumption. Methanol is the most toxic alcohol, and the toxicity of isopropanol is about twice that between ethanol and methanol, ethanol. In general, higher alcohols are less toxic. n-Butanol has been reported to have the same effect as ethanol and is reported to be relatively less toxic (one-sixth of ethanol in the rat test). However, its vapor may cause eye irritation, inhalation may cause pulmonary edema. Acetone (acetone) is not an alcohol but a ketone, and it is reported to have similar toxic effects; it can cause great damage to the cornea.
