Laboratory 2 DRYING OF SOLIDS (Vacuum Tray Dryer) A Final Report Submitted to Engr. Luis K. Cabatingan Instructor‚ ChE 512L By Madeja‚ Rayam John D. July 31‚ 2012 1. Introduction Drying generally means the removal of relatively small amounts of liquid from materials. It is also defined as the transfer of liquid from a wet solid into an unsaturated gas phase. The goal of most drying operations is not only to separate a volatile liquid‚ but also to produce a dry solid of a desirable

turesRule of Mixtures Composite stiffness can be predicted using a micro-mechanics approach termed the rule of mixtures. Assumptions 1. 2. 3. 4. 5. 6. Fibers are uniformly distributed throughout the matrix. Perfect bonding between fibers and matrix. Matrix is free of voids. Applied loads are either parallel or normal to the fiber direction. Lamina is initially in a stress-free state (no residual stresses). Fiber and matrix behave as linearly elastic materials. Longitudinal Modulus Equal strain

Purification of solids Aim: To separate a mixture of carboxylic acid and a neutral substance by treatment with aqueous sodium hydroxide and purifying the carboxylic acid‚ measuring the melting points of the neutral and the acid components. METHOD: A mixture of( 5g) Carboxylic acid and neutral compound were separated by adding 2 mol dm-3 sodium hydroxide (25cm3) to the mixture‚ which separated the water soluble sodium from the water insoluble neutral component‚ by filtration. The solid at the filter

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if it is an element or compound‚ is by studying the actually
