What is the best solvent for dissolving stearic acid?

ABSTRACT: The solubility of stearic acid in ethanol, methanol, ethyl acetate, and acetone has been measured gravimetrically at various temperatures ranging from 301 to 313 K at atmospheric condition. The solubility of stearic acid in ethyl acetate was found to be the highest, followed by ethanol, acetone and methanol.

Is stearic acid soluble?

Stearic acid is a saturated fatty acid that can deposit on the surface in special conditions. This acid is insoluble in water and soluble in ethanol.

How do you dissolve stearic acid?

You can try to dissolve it in hot purified water (but it’ll be dissolved according to its conc. (limited solubility)). Use of a non-ionic surfactant (mix the stearic acid with neat surfactant such as Nonidet P42) and the stearic acid can be ‘solubilized’ in water.

What is the melting point for stearic acid?

69.3 °C
Stearic acid/Melting point

What is the melting point of stearic acid?

Stearic acid melts at 69.3°C (156.7°F) (that’s a higher melting point than beeswax!), making it a very effective hardening ingredient that raises the melting points of our products without adding any waxiness.

Which is the solubility of stearic acid in ethanol?

ABSTRACT: The solubility of stearic acid in ethanol, methanol, ethyl acetate, and acetone has been measured gravimetrically at various temperatures ranging from 301 to 313 K at atmospheric condition. The solubility of stearic acid in ethyl acetate was found to be the highest, followed by ethanol, acetone and methanol.

How to test stearic acid in organic solvents?

Stearic acid in an excess amount was added into a test tube containing 25 mL of organic solvent. The test tube was placed into a constant temperature water bath. The temperature of the water bath was controlled by circulating thermostated water using a refrigerated bath (Techne-RB-5A, USA) and thermo regulator (Techne-RB-5A, USA).

What happens to the crystalline shards of stearic acid?

Some of it vanishes quickly, but the crystalline shards never melt. Some of it vanishes quickly, but the crystalline shards never melt. Some of it vanishes quickly, but the crystalline shards never melt. There are fewer shards, though. Some of it vanishes quickly, but the crystalline shards never melt.
