------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed

I found that among mentioned substances acetone and ethylene glycol are soluble in water‚ therefore we can say that they are polar substances. Besides‚ I observed that biphenyl‚ butyl acetate‚ glycerol and motor oil are nonpolar substance. These compounds were soluble in hexane. Meanwhile‚ magnesium oxide and sodium bromide did not dissolved in either water nor in hexane. Moreover‚ Iodine and aspirin acted different than what I expected

ligand must be created first which requires the use of 3‚5-di-tert-butyl-salicylaldehyde . There are many methods by which this salicylaldehyde can be synthesized but one method with a relatively high yield starts with 2‚4-di-tert-butylphenol. The reaction scheme is shown below in Figure 1. 1 2 3 Figure 1: (1) 2‚4-di-tert-butylphenol ‚(2) 2‚4-di-tert-butyl-6-hydroxymethylphenol‚ (3) 3‚5-di-tert-butyl-salicylaldehyde shown above.

Date : September 2‚ 2013 Course/Yr. : BS Chemistry III Sched : MF 7-10‚ Group#2 Experiment No. 1 Synthesis and Reactivity of Tert-Butyl Chloride I. Objectives : 1. To produce tert-butyl chloride from tert-butyl alcohol 2. To understand the SN1 and SN2 mechanism involved in the reaction 3. To determine the yield of percentage of t-butyl chloride II. Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom

to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation of hydrochloric acid. The rate of hydrochloric acid formation was measured by titrating the acid produced with a base‚ NaOH

Title: Prep of t-Butyl Chloride via SN1 Reaction Purpose: The purpose of this experiment is to synthesize tert-butyl chloride via an SN1 reaction. t-Butyl Chloride was synthesized from t-Butyl Alcohol using hydrochloric acid in separatory funnel; isolation of t-Butyl Chloride was done under distillation conditions. The experiment resulted in 8.29grams of purified compound‚ which is a 66.27 percent yield. Procedure: As per handout with changes Equation: Mechanism: Results: (Scan
Premium Solvent Alcohol Distillation
method used is the addition of a hydrogen halide to an alcohol. In this research‚ tert-butyl alcohol was reacted with cold concentrated HCl to produce tert-butyl chloride. The crude product was distilled to yield a pure tert-butyl chloride. The tert-butyl alcohol‚ together with HCl‚ underwent an SN1 nucleophilic substitution reaction‚ which is composed of three steps—(1) propanation of alcoholic oxygen‚ (2) formation of carbocation‚ and (3) attacking of the nucleophile to the carbocation. The experiment

water test showed that the sample‚ benzyl alcohol was immiscible while ethanol was the most miscible from all the other compounds used. While in Lucas Test which was used to differentiated the primary‚ secondary‚ and tertiary alcohols had turned tert-butyl alcohol into a cloudy solution afterwards. In Chromic Acid Test which was a test for oxidizable compounds or any compounds that possess reducing property would yield to a blue green solution if it reacted positively. This was seen in all the sample
Premium Alcohol Aldehyde Functional group
Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is
