I. Title: Connecting Ground Glass Joints Objective: To learn the proper way to connect a ground glass joint Procedure: Use a female ground glass joint on a round bottom flask Use a male ground glass joint on the claisen head Clean the joints then apply the grease to the male joint Insert the greased male joint into the female joint in a circular motion and check for streaks Observations: Do not apply to much grease to the joint‚ it make cause contamination Check for streaks; if there

Laurie Coleman Chem 3411 Dr. Eidell October 24‚ 2014 Preparation and IR Analysis of 2-chloride-2-methylbutane Line Reaction Abstract The purpose of this experiment was to react 2-methyl-2-butanol with concentrated HCl in order to form 2-chloride-2-methylbutane. The hydrogen for the HCl make the -OH from the 2-methyl-2-butanol into a good leaving group because H2O is formed. The H2O leaves and Cl- is free to bond with the carbocation creating 2-chloride-2-methylbutane. The materials needed

Title: Separation of Mixture of Solids - Experiment 3 Date: 9/21/13 Purpose: This experiment is designed to show the different ways to separate solid mixtures into individual elements. It will also determine whether a substance can be considered “pure” or not‚ as well as determining the solubility of each mixture in water. Procedure: 1) Weigh the amount of the mixture on the digital scale. Separate the Iron out by using a magnet to filter out the Iron element. 2) Take the remaining mixture

objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus. However

Nate Rhodes The Synthesis of Alkenes: Dehydration of Cyclohexanol Organic Chemistry Lab 1 Tuesday 8:00 11/08/11 Paul Jackson Abstract: The goal of this experiment was to form cyclohexene from cyclohexanol through a dehydration reaction. Cyclohexene was successfully synthesized according to the bromine test performed and the IR spectra. There was a percent yield of cyclohexene of 76.1%. Introduction: Alkenes‚ hydrocarbons containing at least one carbon-carbon double bond‚ are important

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

dissolves in the polar ethyl acetate solvent. This phenomenon was illustrated in class before the experiment‚ when it was pointed out why water will not dissolve fluorene‚ fluorenone‚ or transstilbene as readily as a nonpolar solvent such as heptane or toluene‚ or a polar eluent such as ethyl acetate. Those solvents have a much more similar structure to the solutes‚ whereas water’s structure is much different‚ making it not as ideal as a

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
