will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide‚ which will react with eugenol‚ to yield the sodium salt of eugenol in the basic aqueous layer‚ and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation

Steam Generators A steam generator generates steam at the desired rate at the desired pressure and temperature by running fuel in its furnace (used in both fossil-fuel and nuclear-fuel electric generating power stations). It is a complex integration of furnace‚ superheater‚ reheater‚ boiler or evaporator‚ economizer and air preheater along with various auxiliaries such as pulverizers‚ burners‚ fans‚ stokers‚ dust collectors and precipitators‚ ash handling equipment and chimney/stack.

The Steam Engine and the Civil War Question: How did the Steam Engine influence the Civil War and America in itself? Throughout the Civil War‚ there were many people and inventions that positively influenced The Civil War‚ but none other than the steam engine. The steam engine was one of the most influential inventions of the Civil War and America in itself. Before the Steam Engine trade was limited and the American economy was doing very poorly. The causes of this were the rules of trade and

How is the steam engine significant in history? The original steam engine was built in 1712 by a man with a creative‚ innovative mind whose name was Thomas Newcomen. From a never ending search for energy sources came this machine which impacted and changed the world by maximizing production‚ efficiency‚ reliability and minimizing the total times to make products. Through this invention came radical changes in work as well as transportation. The countries that believed in this machines capabilities

Steam Distillation 6.6.12 Aim: To isolate and extract citrol from lemongrass oil using steam distillation. Theory: Impure chemicals are usually purified using distillation‚ allowing the changes in boiling points to separate the substances. Chemicals with high boiling points decompose before reaching the temperature necessary for separation‚ leading to the invention of steam distillation. The contamination is separated at lower temperatures and allows the separation of chemicals from their

Discussion: The purpose of this experiment was to isolate the aromatic hydroxyl compound‚ eugenol from crushed cloves using steam distillation. After conducting the distillation‚ the expected two layers were not visible in the centrifuge tube. Subsequently‚ the extraction and evaporation did not produce the expected oil. This result is probably due to the collection of only water vapor during distillation. From another group’s data‚ 3.80% of the oil was recovered from the cloves in which the major
