Neopentylene
glycol
Chemical name: 2,2-dimethyl1,3-propylene
glycol
Molecular formula:C5H12O2
Neopentylene glycol is a kid of polyhydric alcohol,
soluble in water, cold ethanol, aether,acetone; soluble in
hot acetic ester, benzene, toluene. Neopentylene glycol has
a wide range of application, mainly used in producing unsaturated
polyester resin, alcohol resin,polyurethane foam, polyester
powder coating,insulating material, printing ink, synthetic
plasticizer etc.. Meanwhile, neopentylene is excellent solvent
which can be used in separation of arene, cycloalkyl hydrocarbon.
