Chemical Properties: colorless flammable liquid with moderate ether odor. 20 times more soluble in water, soluble in most organic solvents and mineral oil.
Usage:
It is an excellent solvent. Also excellent surfactants can remove surface grease metal, fabric, glass and plastics. Widely used in paint, ink, leather, printing and dyeing, pharmaceutical, electronics industry.
For nitrocellulose, painting, drying paint, varnish solvent for paints, solvents and ink raw dye dispersant. [2]
1, as a raw material of paint, ink solvents, metal cleaning agent components and dye dispersant
2, mainly used for cellulose nitrate, painting, drying paint, varnish, enamel and paint remover solvents. Also for fiber wetting agents, pesticides dispersant, plasticizer resins, organic synthesis intermediates. Determination of iron and molybdenum reagents. Improved emulsifying properties and mineral oil in the soap is dissolved in the auxiliary solvent.
3.Determination of iron and molybdenum is used as a reagent and solvent, but also for the separation of calcium and strontium nitrate
4.EGBE series: widely used in electronic and hard-surface cleaning industry: to reduce surface tension and improve wettability and cleaning fluid permeability, can be used as metal and glass cleaner.
Brief manufacture process:
By ethylene oxide adducts derived butanol. The n-butanol was added boron trifluoride diethyl ether solution at 20 ℃, and stirring introduction of the ethylene oxide. As the reaction proceeds, the temperature rise automatically when the temperature drops, place for three days. Methanol solution of potassium hydroxide neutralized to pH = 8, namely crude. To add a little crude fractionation after paracetamol, diversity 166-170 ℃ fraction, derived products. Industrial production may be at high temperature and pressure (reaction temperature 180-250 ℃, pressure 2.1-4.6MPa) method of non-catalytic reaction, the reaction 6h. Base catalyst may also be used in near atmospheric pressure and a temperature at the lower.
