smc 51294 In time critical Analysis In time‚ written‚ produced and directed by Andrew Niccol‚ released October 28‚ 2011‚ is a science fiction film. It opens up the mind’s eye to the term “time is money”. The stars‚ Justin Timberlake and Amanda Seyfried‚ brings this across showing two different sides to life. Time zones separate the rich ‚who have time to burn and can live for centuries and the poor ‚who scramble around day-to-day‚ trying to find enough time to stay alive. The rich hike up

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1 ‚‚which represents and OH functional group. The second step of the reaction was to oxidize benzoin to form benzil; this reaction yielded 27.04% benzil. The MP of the benzil was 91O-93O C and the IR spectra revealed no OH functional groups. The last step of the synthesis was a double aldol condensation reaction to form

properties of dibenzalacetone make it a great substance to be used when protecting the skin from the sun. In the experiment performed‚ dibenzalacetone was created from an aldol condensation of 2 portions of benzaldehyde and acetone in sodium hydroxide. The reaction that occurred in this experiment is known as a specific aldol condensation called Claisen-Schmidt. In the reaction‚ the carbonyl of benzaldehyde reacts quickly with the acetone anion to create a hydroxyketone that dehydrates in the presence

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be
