Mix Ethanol with Stearic Acid, use Sulfuric Acid as catalyst.
Sulfuric Acid can be pre-diluted into the Ethanol.
Boil the mixture under reflux. may need to do a few times after each reaction cycle, to use water to wash out the access ethanol & reaction by-product = water. Then re do the same, mix ethanol+sulfuric acid into the partial reactants (Stearic acid + Ethyl stearate) to fully convert the Stearic acid into Ethyl stearate.

Why are sodium stearate solutions alkaline?
Because 'sdoium stearate' is the conjugate base of the weak carboxylic acid 'stearic acid'. Since a solution of stearic acid would be slightly acidic, a solution of sodium stearate will be basic or alkaline.
What is the Product of sodium hydrogen carbonate and stearic acid?
sodium hydrogen carbonate + stearic acid ----> sodium stearate + water + carbon dioxide:) I this helps!
What is the molecular size of aluminum stearate?
Aluminum stearate has a molecular weight of 876.0 Aluminum stearate is used in cosmetics, often as an emulsifier. The aluminum stearate comes from stearic acid.
What are the elements that make up Magnesium Stearate?
As stearic acid is a carboxylic acid, it has carbon, hydrogen and oxygen. Therefore magnesium stearate has the elements stated above along with magnesium.
Chmical reaction when stearic acid add KOH?
Stearic acid reacts with potassium hydroxide to form water and potassium stearate. The reaction equation is C18H36O2 + KOH = C18H35O2K + H2O.

What is glyceryl stearate?
Glyceryl stearate is a wax-like chemical product that comes from glycerin and stearic acid. Glyceryl stearate is a common ingredient in cosmetics.

What is stearate?
Methyl stearate is a chemical often used as an emulsifying agent commonly found in cosmetics and drugs. It is classified as an ester from methyl alcohol and stearic acid.
Which is Enzyme responsible for conversion of stearic acid to oleic acid?
The enzyme which catalyzes the conversion of stearate to oleate is stearoyl-CoA desaturase.
Does magnesium stearate coat the stomach and prevent food from aborbing?
Magnesium stearate is a compound formed from the incorporation of stearic acid with a magnesium ion. It coats the stomach and prevents it from food absorption.
Are fizzers halal?
Im pretty sure they are but not totally. I have just been checking the ingredients; It contains Stearic Acid, magnesium stearate (typically from bovine source) which can derivate from both animal and vegetable fats (see Stearic Acid and magnesium stearate in Wikipaedia). Until it can be confirmed that this comes from a vegetable source it will not be recommended as Halall.
What is stearic acid used for?
It is used in soap making. Stearic Acid is boiled in sodium hydroxide, to make sodium stearate (soap) and water. This is a very old method, and has been superceded by more modern methods.
Why are lubricants added to drugs?
Lubricants can help reduce the friction between the surface of the tablet and the die cavity's wall. Examples of lubricants used in the pharmaceutical industry include magnesium stearate, calcium stearate, stearic acid, polyvinylpyrrolidone 6000, and boric acid.
