Lab 12: Saponification – Making Soap Objective: To make soap using the process call saponification, an organic form of the neutralization reaction that an acid reacts with a base to form a salt. Introduction: A soap is the sodium or potassium salt of a long chained carbohydrate called a fatty acid. A fatty acid usually contains between 12 – 18 carbon atoms. Fatty acids are esters of either animal or vegetable fats. They are called triglycerides if they are solids at room...

Propose another way of synthesizing NMP from the amino ketone hydrochloride salt starting material you used. Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4- chlorobenzotrifluoride and 30 mL of dimethylacetamide (DMA) 2. With stirring, add to this mixture 30 mL of 1.0 M potassium tert-butoxide (caustic alkali!) in tert-butyl alcohol using a syringe 3. Using a simple distillation apparatus,...
6 (10) Spring Problems: (a) Find the displacement, y(t), (in arbitrary units) as a function of time for the mass in a mass-spring system described by the differential equatiorn Zy" 10y' + 8y = 100 cos 3t + 4et assuming that the mass is released from rest at the equilibrium position. (This forcing function is not very realistic.) (b) Assume the equation from part (a) describes a mass-spring-dashpot system with a dashpot containing honey. Imagine that the honey is changed...

what would be my percent yield if i retrieved 3.1020 grams of soap? thank you, please show all work. SAPONIFICATION (HYDROLYSIS OF A FAD Fats and edible oils consitute a special class of esters called riglycerides in which alcohol part of the molecule, the trihydroxy compound glycerol, forms with three molecules of various long-chain carboxylic acids (called fatty acids). Ty reactions of simple esters can also be carried out on fats and oils,i acid-or-base-catalyzed hydrolysis. three ester linkages carboxylic acids...
The alcohol could easily be converted to a tosylate, a good leaving group, and a conventional substitution reaction could have been performed instead of the nucleophilic aromatic substitution (NAS) reaction. Why was the NAS reaction the preferred method? (Hint : Look up the nucleophiles of both reactions on chemical manufacturing site.) Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-...
3. A baseball is projected upward form the top of 448 foot tall bulding with an initial velocity of 48 feet per second. The distance s of the baseball from the ground at any time t, in seconds, is glven by the equation s-16r2 +48t+448 How long will it take the ball to hit the ground? a. b. How high will the ball be in 6 seconds? When will the ball be 448 feet in the air? c. d. If...
