Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol‚ 2.5ml). Then‚ separation though an extraction apparatus and/ or separatory funnel got rid of

combustion than the alcohols with less carbon atoms. So therefore I predict that as the molecular mass increases so does the enthalpy of combustion. The alcohols that I intend to use throughout this investigation are the following 6 alcohols: Ø Methanol - CH3OH solvent; fuel; manufacture of organic chemicals; denaturing ethanol straight chain alcohol. Ø Ethanol - (CH3CH2OH) ethyl alcohol; grain alcohol. A colorless‚ flammable liquid produced by fermentation of sugars. Straight chains. Ø Butane

The natural gas industry in Trinidad and Tobago began with the discovery of gas on land at Mahaica in 1955 by Dominion Oil‚ however the first major natural gas discovery (One Trillion Cubic Feet (Tcf)) was off the East coast of Trinidad by Amoco in 1968 in the Teak offshore field. This was followed up in 1973 by a 2 Tcf find in the South East Galeota acreage. There was however production and utilization of gas before this date. Although the dates referred to mark the first large finds of natural

vaporization of a liquid. The purpose of this experiment is to determine the relationship between the pressure and temperature of the volatile liquids. The pressure will be measured in a sealed vessel that contains different types of liquids such as methanol‚ ethanol and propanol. It will be measured several times at different temperatures. At the conclusion of this experiment‚ the heat of vaporization will be able to be calculated. Materials: To be able to complete this lab procedure‚ the materials

molecular mass is 266.3 grams and its IUPAC name is (RS)-4-(2-hydroxy-3-isopropylaminopropoxy) phenylacetamide. Its melting point 152-155 degrees Celsius‚ has a dissociation constant (pKa) of 9.6 at 24 degrees Celsius. It is soluble in water‚ ethanol and methanol but it is insoluble in ether 2.Atenolol can be synthesized in two parts. The first synthesis is with the reaction of phenol and formaldehyde to form the 4-(hydroxymethyl)phenol the second is treating the 4-(hydroxymethyl)phenol compound with NaCN
