Very interesting. So, the 200 proof, I think 99.7% ethanol that is available for industry, is adulterated. Therefore its better to go with 190 proof, sugar cane ethanol, which I have already sourced?
Oh, on another note, I discovered a local source for hexane, which is used in the processing of soy bean oil. I'm guessing this is a good product?
To produce soybean oil, the soybeans are cracked, adjusted for moisture content, heated to between 140°F and 190°F, rolled into flakes, and solvent-extracted with hexane. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated, are exported abroad, sold as "vegetable oil," or end up in a wide variety of processed foods.
