pubchem.ncbi.nlm.nih.gov/compound/heptaneHeptane is a straight-chain alkane with seven carbon atoms. It has been found in Jeffrey pine (Pinus jeffreyi). It has a role as a non-polar solvent and a plant metabolite. It is a volatile organic compound and an alkane. N-heptane is a clear colorless liquids with a petroleum-like odor. Less dense than water and insoluble in water.
pubchem.ncbi.nlm.nih.gov/compound/Isopropyl-alcoholIsopropyl alcohol or 2-propanol is an isomer of 1-propanol. It is a colorless liquid having disinfectant properties. It is used in the manufacture of acetone and its derivatives and as a solvent. Topically, it is used as an antiseptic. Small amounts of this alcohol are produced naturally by gut microbial flora.
/ethanol-ethyl-alcohol... CachedEthanol is a liquid at standard conditions. However, at low temperature and/or very high pressures it becomes a solid. The phase diagram for ethanol shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the ethanol boiling point with changes in pressure.
