Preparation and isolation of an Ester Aim: To make an ester and purify it Background Theory: Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed. The general formula of an ester is RCOOR’ in which R is the

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

Book of Esther Review 1. (Source Sheet 1‚ #5) For the first time‚ there are two major Jewish communities: one in Persia and one in Eretz Yisrael. There is a tension between the two communities. The community in Persia is assimilated and they were high up in status. The two communities do not mention one another; there is no mention of Shushan in any of the books of the people who lived in EY. In Persia‚ the Jews were very assimilated - the Jews intermarried and were economically very well off

margarine named Benecol. Stanol ester is the active ingredient that provides the lower cholesterol benefit. The success of Benecol and stanol ester would depend on Raisio’s ability to market and distribute the product worldwide. Synopsis of Case While studying the effects of rapeseed oil on blood cholesterol levels Raisio was presented with the idea to research plant sterols. Exploration into plant sterols proved valuable as it could be used to produce stanol ester. The Benecol launch in 1995

Raisio’s Research and Development program further developed a medical use of a byproduct of pine-wood pulp or stanol ester. Raisio had found a unique way of processing the plant stanol which allowed it to become refined and fat-soluble. They studied it further and found it to have a profound cholesterol-reducing effect when consumed. The findings were published in New England Journal of Medicine in November 1995; “after a 14-month trial‚ a daily intake of 25 grams reduces total cholesterol in

(“Benecol‚” 2010). Benecol has become a successful additive to multiple product lines due to its unique ingredient of plant stanol ester. The ingredient has been proven to reduce cholesterol levels and can easily be added to any food (Grant‚ 2010). Raisio‚ up until 1997‚ produced much of the plant stanol it needed and was self-sufficient in its exploitation of stanol ester technology (Grant‚ 2010). Raisio then made the decision to become part of Johnson & Johnson in order to gain global marketing‚ manufacturing

Raisio‚ a Finnish grain and chemical company‚ is the proud owner of a product that has been deemed one of the ten most important nutritional innovations in the world (“Benecol®‚” 2010). This product is a unique compound composed of plant stanol esters and has been scientifically proven to help lower cholesterol levels in humans. With the prevalence of high cholesterol in the world population and the incidence of mortality associated with a high cholesterol level‚ it is no wonder that Raisio had
