Liquid paraffin
English name: White Oil
CAS registration no. : 8042-47-5; 8012-95-1
Molecular formula:
The basic physical and chemical properties.
Oily liquid. 0.831 ~ 0.831, the flash point (open) 164 ~ 223 ℃, the movement viscosity 46 was/s (5.7 ~ 40 ℃), the acid value of 0.05 or less. Of acid, light and heat stability, insoluble in ethanol, soluble in ethyl ether, benzene, petroleum ether, etc., and can be with most of the fatty oil miscibility. For liquid mixture of hydrocarbons, the main ingredient for C16 ~ C31 microcomputer is heterogeneous mixture of alkanes.
