1.features of stearic acid:

Physical and chemical properties:

Melting Point (°c): 70-71

Boiling Point (°c): 383

Relative Density (water=1): 0.87 Relative Vapor Density (air=1): 9.8 Saturated Vapor Pressure (kPa): 0.13 (173.7°c)

Flash Point (°c): 196 Ignition Temperature (°c): 395 Solubility: Not dissolve in water; slightly soluble in ethanol; easily Soluble in acetone, benzene; soluble in ether, chloroform, carbon tetrachloride, etc.

2.Application:

Stearic acid is useful as an ingredient in making candles, plastics, dietary supplements, oil pastels and cosmetics, and for softening rubber. It is used to harden soaps, particularly those made with vegetable oil.

Stearic acid is also used as a parting compound when making plaster castings from a plaster piece mold or waste mold and when making the mold from a shellacked clay original. In this use, powdered stearic acid is dissolved in water and the solution is brushed onto the surface to be parted after casting. This reacts with the calcium in the plaster to form a thin layer of calcium stearate which functions as a release agent.
