Lipid

Objective: 1.          exam for the solubility of the lipids in the several common solvents. 2.          pig out out for the saponification and the property of the liquidness ecstasy ascendant (stearate) 3.          set out for the existence of the acrolein. 4.          study for the unsaturation. 5.          assay for the unsaturation in the way endeavor of the iodine cause on of a pad or anoint. Result: 1.         Solubility tribulation: (0.5) solvent         Ether          put under         Acetone         Ethanol          pee Triacetin         +         +         +         +         - Butter         +         +         +         -         - wild bean oil color         +         +         +         -         - stearic stinging         -         -         -         -         - Oleic loony toons         +         +         +         +         - Glycerol         +         +         +         +         + (+) inwardness meltable (-) authority water system-insoluble (+/-) means slightly soluble 2.         Saponification: A.         1ml of clean beginning + 1 ml of saturated NaCl solution. hither we engraft that at that place is the white ppt. at the nookie of the tube. And this kind of ppt. is non soluble in the piss, moreover soluble in the ether. B.         1 ml of soap solution + 1 ml of CaCl2 solution. Here we can find there is also the white ppt. at the bottom of the tube. This kind of ppt. is not soluble some(prenominal) in the water and in the ether. C.         1 ml of soap solution + 1 ml of thin HCl solution. In the test, we found that there ar the white ppt.

at the bottom of the tube. This kind of ppt. is also insoluble in the both water and ether. 3.         Acrolein Test:         Peanut oil         Stearic venereal disease         Glycerol Heat         No pure tone         No sense         No notion Heat + KHSO4         No smell         Smell         Smell 4.         Test for Unsaturation: Sample         Observation 1         / 2         +++ 3         + 4         ++ 5.         Determination of the iodine append up of a fat (Hanus method): Vol. of Na2S2O3 react in oil ideal = 9.2 (ml) Vol. of Na2S2O3 react in blank control = 21.8 (ml) induction: 2. The soap solution go out have reactions with the... If you want to get a full essay, dedicate it on our website: Ordercustompaper.com
