Ethanol toxic hazard properties

Properties Hygroscopic, white powder. Mp 71C. Very soluble in water and ethanol alcohol. Hazard Toxic by inhalation and ingestion. 

Properties Colorless liquid. Bp 119C, d 0.873 (20/ 20C), refr index 1.4153 (25C), flash p 80F (26.6C) (TCC). Miscible with water, ethanol, toluene, acetone, carbon tetrachloride, hexane, and ether. Hazard Flammable, moderate fire risk. Toxic by ingestion and inhalation. 

Carbon dioxide is, by far, the most attractive SCF for many reasons It is inexpensive and abundant at high purity (food grade) worldwide and it is nonflammable, non-toxic, and environment friendly moreover, its critical temperature T = 31 °C) permits operations at near-ambient temperature which avoids product alteration and its critical pressure (= 74 bar) leads to acceptable operation pressure, generally between 100 and 350 bar. In fact, supercritical carbon dioxide behaves as a rather weak nonpolar solvent, but its solvent power and polarity can be significantly increased by adding a polar cosolvent that is chosen among alcohols, esters, and ketones. Ethanol is often preferred because it is not hazardous to the environment, not very toxic, and available pure at low cost. Hydro fluorocarbons (HFCs) are very costly and their specific properties rarely justify their use in the replacement of carbon dioxide.
