Molecular formula : C25H48O4
MW : 412.66
CAS No. :103-24-2
nature : the almost transparent colorless liquid. Solidification point of -65 ° C, the boiling point of 376 ° C and 237 ° C (0.67kPa) ,208-210 ° C (0.267kPa), the relative density of 0.917 (25 ° C), 1.4512 refractive index, a flash point of 213 ° C. The majority of soluble organic solvent, do not dissolve in water.
preparation methods : by oleic acid by ozonation system in azelaic acid, azelaic acid by, and 2 - ethyl hexanol in sulfuric acid-catalyzed esterification derived DOZ. The consumption of raw materials fixed : Azelaic Acid 500 kg / t, 2 - ethyl hexanol 670kg / t.
purposes : the goods of good cold plasticizer. With PVC, and vinyl chloride-vinyl acetate copolymer, polystyrene, polyvinyl acetate, cellulose acetate butyrate, cellulose nitrate, ethyl cellulose as a good compatibility. Its low viscosity, high boiling point, plasticized high efficiency, and the migration of volatile small, but has excellent heat-resistance, wire insulation and right plastipaste viscosity stability, good resistance to cold than DOA. In leather, film, sheet, wire and cable sheathing, plastipaste, can give good products at low temperature performance. The goods may either alone or with other plasticizers tie for nitrile rubber, styrene-butadiene rubber, neoprene synthetic rubber such as plasticizers.
