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.
Stearic acid reacts with ethanol in the presence of a strong acid catalyst, such as sulfuric acid, to form ethyl stearate and water in a process called esterification. The reaction involves the condensation of the carboxylic group from stearic acid with the hydroxyl group from ethanol, resulting in the formation of ethyl stearate. Purification steps are usually necessary to isolate the final product.

Why are sodium stearate solutions alkaline?
Sodium stearate solutions are alkaline because stearic acid, which is the precursor to sodium stearate, is a weak acid. When stearic acid reacts with sodium hydroxide to form sodium stearate, the resulting compound dissociates in water to release hydroxide ions, increasing the pH of the solution and making it alkaline.
What is the Product of sodium hydrogen carbonate and stearic acid?
The reaction between sodium hydrogen carbonate and stearic acid would likely produce sodium stearate, water, and carbon dioxide. Sodium stearate is a type of soap that can be used in various applications such as in making cosmetics or cleaning products.
What is the name of the salt produced from stearic acid and triethanolamine?
The salt produced from stearic acid and triethanolamine is called stearate triethanolamine, also known as triethanolamine stearate. This compound is commonly used as an emulsifier and stabilizer in cosmetics and personal care products.
What is the molecular size of aluminum stearate?
The molecular size of aluminum stearate can vary depending on its structure and the number of aluminum and stearate units present in the molecule. It is a salt formed by the reaction of stearic acid and aluminum hydroxide, typically resulting in a larger molecular size compared to the individual components.
What are the elements that make up Magnesium Stearate?
Magnesium stearate is composed of two main elements: magnesium and stearic acid. It is a white, powdery substance commonly used in the pharmaceutical and supplement industries as a lubricant or anti-adherent in the manufacturing process of tablets and capsules.

What substances have NaC18H35O2?
NaC18H35O2 could refer to sodium stearate, which is the sodium salt of stearic acid. Stearic acid is a saturated fatty acid commonly found in animal and vegetable fats. Sodium stearate is often used as an ingredient in soaps, cosmetics, and personal care products as a surfactant and emulsifier.
Chmical reaction when stearic acid add KOH?
When stearic acid is added to potassium hydroxide (KOH), it undergoes saponification to form potassium stearate and water. This reaction is commonly used in soap making processes. The reaction can be represented by the chemical equation: C17H35COOH + KOH -> C17H35COOK + H2O
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 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.
How do you manufacture potassium stearate?
Potassium stearate is typically manufactured by reacting stearic acid with potassium hydroxide in a controlled environment. The reaction forms potassium stearate, which is then purified and dried to obtain the final product. The process may involve additional steps such as filtration and crystallization to ensure the purity of the potassium stearate.
What is the method of preparation aluminum stearate?
Aluminum stearate can be prepared by reacting stearic acid with an aluminum salt (such as aluminum chloride) in a solvent like toluene or xylene. The reaction typically occurs in the presence of a base, followed by filtration and drying to obtain the aluminum stearate product.
