Molecular formula : C6H14O2
MW : 118.18
CAS No. :111-76-2
nature : colorless flammable liquid, with intermediate ether taste. Solidification point of -40 ° C, the boiling point of 171 ° C and relative density of 0.9015 (20 / 4 ° C), the refractive index of 1.4198, the flash point of 61.1 ° C, the vapor pressure (20 ° C) 0.101kPa, 472 ° Cspontaneous combustion point. 20 times more soluble in water, soluble in organic solvent and the majority of mineral oil. Petroleum hydrocarbons with a high dilution ratio.
Preparation : ethylene oxide generated from the addition of n-butanol. Will butanol at 20 ° C under the accession of boron trifluoride diethyl ether solution, mixing in the next one to ethylene oxide. As the reaction proceeded, temperature rise automatically when the temperature dropped, placed three days. Using potassium hydroxide and methanol solution to pH = 8, derived crude. Coarse materials to a small pair of paracetamol after fractionation, Diversity 166-170 ° C fractions, ie finished. Industrial production for use in high temperature and high pressure (180-250 ° C reaction temperature, the pressure of 2.1-4.6MPa), the non-catalytic reaction, reaction 6h. Also available alkali catalyst in the near atmospheric pressure and low temperature.
purposes : mainly used for nitrocellulose, paint, fast-drying paint, varnish, enamel paint remover and solvents. Also for fiber wetting agent, pesticides dispersant, resin plasticizers, synthetic organic intermediates. Determination of iron and molybdenum reagents. Emulsion to improve performance and to mineral oil soap dissolved in the auxiliary solvent.
