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.

BeauStearic 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.
