Name: David Kennedy Date: 11/5/14 Project No: 131 Title: Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate Abstract: The targeted trisubstituted ethylene compound Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate and its copolymer with styrene was prepared in this lab. The base catalyzed Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure

Introduction: Dealing with chemicals is an essential part of a chemical engineer’s job. It is therefore crucial to be able to accurately identify the composition of a chemical to be able to work with it. Indeed‚ different species have different physical and chemical properties which dictate their uses and applications. Furthermore‚ this kind of analysis is important in quality control since the detection of unwanted chemicals may lead to the rejection of a product for example. In addition to qualitative

Using orange (Citrus sinensis) as an airfreshener Review of related literature: Octyl acetate Octyl acetate‚ or octyl ethanoate‚ is an ester that is formed from octanol (octyl alcohol) and acetic acid. It is mostly found in oranges and other citrus products. Octyl acetate can be synthesized by a condensation reaction: C8H17OH + CH3COOH → C10H20O2 + H2O Uses Because of its fruity odor‚ octyl acetate is used as the basis for artificial flavors and in perfumery. It is also as a solvent for

Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

While in Lucas Test which was used to differentiated the primary‚ secondary‚ and tertiary alcohols had turned tert-butyl alcohol into a cloudy solution afterwards. In Chromic Acid Test which was a test for oxidizable compounds or any compounds that possess reducing property would yield to a blue green solution if it reacted positively. This was seen in all the sample

its major application is for cellulose acetate‚ a synthetic textile. Acetic anhydride is also a reagent for the production of heroin. Ester production Acetic acid can be used for synthesis of various esters like ethyl acetate‚ propyl acetate‚ n-butyl acetate‚ isobutyl acetate etc. These esters are commonly used as solvents for inks‚ paints and coatings. The esters are produced by acid catalyzed reaction of acetic acid with the corresponding
