was carried out‚ the hexane and methanol extracts from roots of A. paniculata did not show any significant activity at various treatment doses‚ when observations were taken after 24 hours (table 2). When the observation period was extended to 48 hours‚ antifeedant activity significantly enhanced to 50.53 % at maximum dose (0.1 %) with hexane extract. Antifeedant activity was significantly superior at the higher doses of 0.03%‚ 0.05%‚ 0.07% and 0.1% with methanol extract after 48 hours. Like in

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

In this experiment‚ we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask‚ we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out

Theory: In the production of biodiesel from cooking oils (glycerides) and methanol are combined with sodium hydroxide as a catalyst. This causes the oils to break apart and reaction of the oils with the methanol. As seen in Figure 1‚ this produces biodiesel (in the form of esters) and glycerol. Figure 1: The production of biodiesel (esters) from glyceride (cooking oils) and an alcohol (methanol). In combustion‚ a substance can be completely or incompletely combusted. In complete combustion‚

ENG GROUP LEADER‚ MEASUREMENT AND PROCESS CONTROL ENGINEERING ATCO PIPELINES Introduction In the transportation of natural gas from wellhead to consumer‚ service conditions will be encountered which may cause the gas and equipment used to regulate and control pressure to experience freezing conditions. Ignoring these design considerations will result in reduced facility reliability and increased operating and maintenance costs. Regulator

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

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

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
