ABSTRACT: Water is omnipresent in foodstuffs and the surrounding atmosphere. In principle‚ the moisture content of a food can therefore be determined accurately by measuring the number or mass of water molecules present in a known mass of sample. It is not possible to directly measure the number of water molecules present in a sample because of the huge number of molecules involved. A number of analytical techniques commonly used to determine the moisture content of foods are based on determinations

cyclohexanol + H3O+ Throughout the lab some terms may be used that may be unfamiliar. Here are a few definitions of commonly used terms: Distillation: the evaporation and subsequent collection of a liquid by condensation as a means of purification Extraction: To obtain from a substance by chemical or mechanical action‚ as by pressure‚ distillation‚ or evaporation. Decanting: To pour off without disturbing the sediment. A number of different lab techniques were used throughout the lab‚ here

it is deodorized to produce a product which is stable and bland in flavor. In the pre-stripping and deodorizing column‚ deacidification and deodorization process happen concurently. Deodorization is a high temperature‚ high vacuum and steam distillation process. A deodorizer operates in the following manner: (1) dearates the oil‚ (2) heat up the oil‚ (3) steam strips the oil and (4)cools the oil before it leaves the system. The fatty acid vapor leaving the deodorizer are condensed and

four steps. The basicity had to be tested to check and see whether the unreacted Benzoic acid was removed. Finally‚ the excess water had to be removed as well to achieve a pure dichloromethane organic layer that would be used for simple distillation. The distillation apparatus separated the dichloromethane from the methyl benzoate by difference in temperature. The Methyl Benzoate could only be achieved when the temperature climbed to 198-199 Celsius. The product will be obtained if the steps are taken

1. Lambanog can be produced using the process of distillation. The freshly gathered coconut tree sap is oyster white in color‚ has a nearly neutral pH‚ and is already inherently sweet tasting by nature. Allowed to ferment further if too sweet and less alcoholic. 2. Put desired amount of tuba or coconut sap in distillation chamber. Apply heat until it evaporates. 3. Condensed the evaporated alcohol using flowing water at the top of the distillation chamber to liquefy the alcohol in gaseous phase

to benzene [71-43-2] to form cumene [98-82-8]‚ which is then oxidized by air to cumene hydroperoxide‚ and cleaved in the presence of an acid catalyst like zeolite. Phenol [108-95-2] and acetone [67-64-1] produced in the process are recovered by distillation. Ratio of phenol to acetone is 1:0.6. (2) By Dehydrogenation of 2-proponal The hydration of propene [115-07-1] gives 2-propanol [67-63-0]‚ which is then dehydrogenated to acetone.

simple distillation and the IR is then obtained. Techniques and equipment used throughout the experiment include a reflux apparatus‚ separatory funnel for isolation‚ vacuum filtration‚ and simple distillation. The reflux condenser is used to allow thorough distillation of the product with the use of heat to accelerate and stir while vapors fall back into the round bottom flask. Isolation of product is used with the help of the separatory funnel and vacuum filtration. Simple distillation is used
