Oxidation of an Alcohol: Oxidizing Methoxybenzyl Alcohol to Methoxybenzaldehyde Using Phase-Transfer Catalysis PURPOSE OF THE EXPERIMENT Oxidize methoxybenzyl alcohol to methoxybenzaldehyde‚ using sodium hypochlorite as the oxidizing agent and tetrabutylammonium hydrogen sulfate as the phase-transfer catalyst. Monitor the progress of the reaction by thin-layer chromatography. BACKGROUND REQUIRED You should be familiar with extraction‚ evaporation‚ and thin-layer chromatography techniques

There are too many reasons to prove that staying up late is a bad habit‚ and it might affect people’s whole life. If you have that kind of problems‚ adjusting your life cycle time will be your best choice because you will never know when your body will stop functioning. The most serious thing affects people for staying up late is health problem. Many people will not feel anything from their bodies until they get old. As they keep this bad habit for a few more years‚ their immune system may be so weak

ALCOHOLS Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. For the purposes of UK A level‚ we will only look at compounds containing one -OH group. For example: Primary alcohols In a primary (1°) alcohol‚ the carbon which carries the -OH group is only attached to one alkyl group Some examples of primary alcohols include: Secondary alcohols In a secondary (2°) alcohol‚ the carbon with the -OH group attached is joined directly to

Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)

Comparing the enthalpy changes of combustion of different alcohols Aim In this experiment I will investigate the enthalpy changes of combustion. In particular I will be investigating the enthalpy change of combustion for different alcohols. I hope to investigate some of the homologous series alcohols‚ as well as a few structural isomers of these alcohols. Background & theory Enthalpy cannot be measured. What we can actually measure is the enthalpy change from the reactants to the products.

Lobbying in Alcohol industry in EU 1. Alcohol industry in EU The economic role of the alcoholic drinks industry is considerable in many European countries. Alcohol excise duties in the EU15 countries amounted to €25 billion in 2001‚ excluding sales taxes and other taxes paid within the supply chain – although €1.5 billion is given back to the supply chain through the Common Agricultural Policy. Due to the relative inelasticity of the demand for alcohol‚ the average tax rates are a

Alcohol Anonymous Paper Alcoholism Alcoholism is a very dangerous disorder that many people are suffering from. A lot of Americans don’t realize that alcoholism is a big deal‚ and they may not even know someone very close to them is an alcoholic.

I walked in nervous and I wasn’t even there to share if I were an alcoholic. I introduced myself to the leader
