Experiment: The Saponification Value Of Coconut Oil And Walnut Oil

813 Words4 Pages

The experiment was carried out successfully as the saponification value of olive oil was identified by the hydrolysis of the oil under basic conditions (potassium hydroxide) , leaving behind glycerol and the potassium salts of the fatty acid(soap) and by carrying out a titration of the reference titre (A) and blank titre (B) against HCL. The saponification value was calculated from the difference in tires and was identified as 190.84 mg/ml. The saponification values for Coconut Oil and Walnut oil were calculated to be 252.45 and 183.73 mg/ml.

The experiment was carried out sucessfully as the saponification value of Olive oil was identified by the hydrolysis of the oil under basic conditions (potassium hydroxide) and by carrying out a titration of the product of hydrolysis with HCL to determine the saponification value. The saponification value was calculated from the difference in titres A (Reference titre) and B(Blank titre) and was calculated to be 190.84 mg/ml. The saponification values for Coconut Oil and Walnut oil were calculated to be 252.45 and 183.73 mg/ml.

Firstly the saponification of the olive oil took place sucessfully by boiling the olive oil with concentrated alcoholic KOH , the hydrolysis of the oil occurred as glycerol and the potassium salts of fatty acids (soap) were produced. This occurred because even though hydroxides existed in the aqueous phase and triglycerides existed in the organic phase by increasing agitiation , the reactants happened to be

    In this laboratory experiment, 3.030 g of Isopentyl Acetate was synthesized and formed by the esterification of acetic acid with Isopentyl Alcohol. 1.0 mL of Sulfuric acid was used as a catalyst in the reaction. The excess Isopentyl Acetate was used to shift the reaction to the right for esterification to occur. During the extraction, the excess of acetic acid and Isopentyl alcohol was extracted with sodium bicarbonate, and further purification of the Isopentyl acetate was done after through drying with anhydrous sodium sulfate and through simple distillation. The percent yield of the Isopentyl Acetate was 46.6 percent with a theoretical yield of 6.502g. In this laboratory experiment the acetic acid was in excess and the Isopentyl Alcohol was the limiting reagent,

    Introduction The purpose of the experiment was to synthesize and purify isopentyl acetate or banana oil. In order to perform this reaction, the mixture containing excess acetic acid and isopentyl alcohol was heated under reflux. The methods of extraction, drying, and distillation were then used to help purify the isopentyl acetate. After the completion of all these processes, we were able to determine the yield and analyze our isopentyl acetate.

    To start with, the Mediterranean diet is not a diet per say but more of a way of life of the people of the Mediterranean basin. It is more of a term for the abridgement of the several traditional foods and eating patterns of the 16 countries that border the Mediterranean basin, most notably Italy, Greece, Portugal, and Spain. These countries appear to share common dominating dietary traits despite certain degrees of differences in their religions, cultures, educational levels, and economic prosperity. The low incidence of cardiovascular diseases and obesity among the people of the Mediterranean basin despite their known consumption of high-fat diets was what actually aroused interest in their dietary habits.

  • Isolating Trimyristin To Yield Myristic Acid

    There are three main types of ester hydrolysis reactions: base-facilitated hydrolysis (saponification), acid-catalyzed hydrolysis (with the reverse reaction the Fischer Esterification), and enzymatic hydrolysis, triggered by lipases. Base-facilitated hydrolysis generally uses aqueous NaOH as a reagent, providing the base that attacks the carbonyl and begins the hydrolysis. Saponification hydrolyzes esters into carboxylic acids or fatty acids and alcohols. This has been used for thousands of years to produce soap from fatty acids as the salts produced from saponification can dissolve fats, surrounding them with micelles and allowing them to be easily removed with water1. It can also be used to produce glycerol from triglycerides.

    The reaction to synthesize benzocaine was known as a Fisher esterification reaction. The Fisher esterification was reaction between alcohol and carboxylic acid in the presence of acid. The reaction was used to form an ester. In the experiment, sulfuric acid acted as a catalyst and necessary for this reaction to occur. There was a change between the –OH group of carboxylic acid to an –OCH2CH3 group in the reaction.

    Most importantly, this reaction is reversible, therefore, an excess of acetic acid is added to shift the equilibrium to favor the ester product. Also, to acid is removed from the product mixture for the ester to separate from the water by neutralizing the acid with a base. Overall, banana oil will be synthesized from acetic acid and isopentyl alcohol. Results:

    The reaction is then put under reflux. This produces the sodium salt of salicylic acid known as sodium salicylate. The end products of saponification are alcohol and carboxylic acid. Therefore, in the second step (2), the sodium salicylate collected is then acidified using sulphuric acid to convert the organic salt into the protonated carboxylic acid, salicylic acid. Since the acid is a solid, it be easily isolated from the alcohol produced, methanol, and then purified by crystallisation.

    If the sample to be analyzed is non-volatile, the techniques of derivatization or pyrolysis GC can be utilized. Gas chromatography (GC) has been an indispensable analytical technique in the application of fatty acid determinations in oilseed plant breeding, biosynthesis, and human metabolism. As well as the characterization of complex mixtures of geometric isomers when combined with other chromatographic separations and spectroscopic identification. Plant cultivators utilize GC as a more accurate and fast method to evaluate the differences and inheritance of fatty acids in oilseed crops such as rapeseed. flaxseed, and safflower.
