is growing steadily and has reached almost 600 KTA which is expected to increase further by another 400 KTA by the end of 12th 5 year plan. There is a need for capacity expansion for Benzene. The primary source for benzene supply is reformate or toluene transalkylation based production units which accounted for about 400 KTA and 620 KTA of capacity respectively. Lower purity Benzene from coke ovens also accounts for small amount of supply addition. A new aromatic complex with Benzene capacity of

to prepare cyclohexene while using sulfuric acid as a catalyst. The mixture of cyclohexanol with sulfuric acid is heated in a flask equipped with a fractionating column‚ forming water. Further heating promotes the distillation of water and cyclohexene by the principle of stem distillation. A bromine test can be later done to ensure that the end product is an alkene. HYPOTHESIS The amount of cyclohexene forms will be greater than the amount of cyclohexanol prepared. PROCEDURE

Edward Cross Organic Chemistry December 10‚ 2012 Title Steam Distillation of Cloves and Extraction of Eugenol Authors Edward J. Cross* Summary The isolation of Eugenol from Cloves begins with whole cloves and then using a steam distillation apparatus to obtain the cloves oil substance. Then with the mixtures of water and dichloromethane to form two immiscible layers. The layers were dichloromethane substance and aqueous The entire substances that are separated into two individual

isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction and distillation. Isopentyl acetate was analyzed by infrared spectroscopy and 1H NMR spectroscopy. Reaction Scheme: Mechanism: Key features of the Fischer Esterification mechanism are: a. protonation of the carbonyl group‚ b. the formation of the tetrahedral

4) Describe methods of separation and purification: filtration‚ crystallisation‚ distillation‚ fractional distillation. Filtration: A way of separating Insoluble Solids from Liquids. With Filter Paper and a Funnel. Crystallisation: Separating Liquids from soluble Solids. Done in Petri dish. Distillation: Separating Liquids depending on their Boiling points. Fractional Distillation: Same as Distillation but separating more than two Substances with different Boiling Points. 5) Understand

Benzene is a special case of conjugation that leads to an especially stable bonding arrangement. The benzene ring consists of six sp2 hybridized carbon atoms in a regular hexagon. Each carbon forms two σ-bonds with adjacent carbons‚ and a third σ-bond with a hydrogen atom. The 2p orbital on each atom is available for π-bonding. Interaction between the p orbitals on the six carbon atoms forms a conjugated system of π-electrons. Molecules with this bonding arrangement are called aromatic molecules

Isolation of the Major Component of Clove Oil Pre-Lab Questions: 1.) Briefly explain the concept of steam distillation. What is the difference between a simple distillation and a steam distillation? When a mixture of two immiscible liquids are distilled it is referred to as codistillation. This process is referred to as steam distillation when one of the liquids is water. This distillation is used to separate organic liquids from natural products and reaction mixtures in which the final product
