Special Report Methyl ethyl ketone – A techno-commercial profile M ethyl ethyl ketone (MEK or 2-butanone) is an organic compound with the formula CH3C(O)CH2CH3. Its CAS number is 78-93-3. The colorless liquid ketone has a sharp‚ sweet odour of butterscotch and acetone. It is produced industrially on a large scale‚ and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent. With natural and synthetic resins‚ MEK produces solutions with low viscosity

GAS CHROMATOGRAPHY EXPERIMENT The purpose of this experiment is for the student: 1) to learn the general theoretical aspects of gas chromatography as a separation method‚ 2) to learn how to operate gas chromatographs specific to COD‚ 3) to become familiar with using the gas chromatograph (GC) to qualitatively identify components of mixtures‚ 4) to be introduced to and to interpret the quantitative data available via gas chromatography‚ 5) to gain insight into how the GC technique is used

In this paper‚ tin(II) chloride dihydrate (SnCl2·2H2O)‚ an inexpensive Lewis acid‚ was evaluated as catalyst on the ethanolysis of oleic acid‚ which is the major component of several fat and vegetable oils feedstocks. Tin chloride efficiently promoted the conversion of oleic acid into ethyl oleate in ethanol solution and in soybean oil samples‚ under mild reaction conditions

yields‚ whereas the first trial of microwave synthesis or one-pot synthesis had a yield of 40-70%. However‚ this synthesis was found to be inconsistent and exceeded the pressure limit in microwave. To overcome the pressure problem‚ a base potassium tert-butoxide was added to dicyclopentadiene in diglyme and microwaved for 10 in @ 185oC to obtain cyclopentadienyl anion. This anion was added to a solution FeCl2.4H2O in DMSO and ferrocene was obtained in 5 minutes with a yield of 86%. To further

Chapter I INTRODUCTION Plastics found everywhere. Bottles‚ utensils‚ food packagings are some examples of plastics that we use and see in our daily lifestyle. We can easily have plastics for our convience because it was sold in our market directly thus spending a little of our money. Behind these things our typical perception about plastic is just a bit of what plastics really are. For those people who are concious about our environment ‚ they say that plastics cause a wide environmental problem

Market and Nonmarket Environments Market environment includes those interactions (which involve voluntary economic transactions and the exchange of property) between firms‚ suppliers and customers that are governed by Markets and Contracts. Nonmarket environment is composed of the social‚ political and legal arrangements that structure interactions (between the firm and individuals‚ interest groups‚ govt. entities‚ and the public which are intermediated not by markets but by public and private
