Additional_detail: Nature: colorless, transparent
liquid. For the polar inert
solvent. In addition to
halogenated hydrocarbon outside
with water and most organic
solvents arbitrary mixed. Melting
point -61 ℃, the boiling point
152.8 ℃, 76 ℃ (5.2 kPa), the
relative density of 0.9445 (25 /
4 ℃), refractive index of
1.4269. Flash point 58 ℃,
spontaneous combustion, 445 ℃.
On a variety of organic compounds
and inorganic compounds have a
good ability to dissolve and
chemical stability. 25 ℃ the
vapor pressure to 0.493 kPa.
Use: DMF is a very wide use of
chemical raw materials, is also a
very broad use of the excellent
solvent. DMF on a variety of
polymers such as polyethylene,
polyvinyl chloride, the PAN,
polyamide, and so are a good
solvent, the PAN can be used for
synthetic fibers such as the wet-
spinning, polyurethane Synthesis
for the plastic film; can also
remove paint for the paint
remover; It can also dissolve
some of the low solubility of the
pigment to paint with a dye
characteristics. DMF for aromatic
hydrocarbon extraction and for
four from carbon fraction of the
separation and recovery of
butadiene and isolated from the
C5 distillate isoprene recovery,
also can be used as paraffin
isolated from non-hydrocarbon
component of effective Reagents.
It terephthalate acid and the
solubility of a good selective:
acid in DMF is greater than the
solubility of terephthalic acid,
the acid in a Amide in a solvent
extraction or part of
crystallization of the two can be
separated. In the petrochemical
industry, DMF can be used as
absorbent gas, used to separate
gas and refined. In organic
reactions, DMF reaction not only
widely used as solvents, organic
synthesis is also an important
intermediate. Pesticide industry
can be used to produce
chlordimeform; can be used in the
pharmaceutical industry of iodine
amine pyrimidine, doxycycline,
cortisone, vitamin B6, iodine
glycosides, flooding Nao net,
thiadiazole pyrimidine, N-formyl-
dissolved sarcoma, anti - Of
histidine, methicillin-mustard,
nitrogen mustard Bian, Central
Asia has been Glauber urea,
Ceftiofur fluorouracil, bleeding
acid, the United States-at times,
megestrol acetate, bile-
dimensional him,
chlorpheniramine, and so on. DMF
in hydrogenation,
dehydrogenation, dehydration and
from the reaction of hydrogen
halide in a catalytic role in
reducing the temperature,
increase product purity.
