Vidallon‚ Mark Louis P. Date Performed: February 20‚ 2012 CHEM44.1 2L Date Submitted: March 12‚ 2012 MIXED-ALDOL CONDENSATION Synthesis of Cinnamaldehyde I. 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

environmental problems. Waste plastic disposal and excessive use of fossil fuels have caused environment concerns in the world. Both plastics and petroleum derived fuels are hydrocarbons that contain the elements of carbon and hydrogen. The difference between them is that plastic molecules have longer carbon chains than those in LPG‚ petrol‚ and diesel fuels. Therefore‚ it is possible to convert waste plastic into fuels. The non-catalytic pyrolysis process is the nearest technique to commercialization considering

functional group containing OH- when it is a substituent in an organic compound. It is also known as the characteristic functional group of alcohols and phenols. On the other hand‚ carbonyl group refers to a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. It is known as the characteristic functional group of aldehydes and ketones instead. In this experiment‚ hydroxyl- or carbonyl- containing samples were given to the group for examination. The samples

163 CHAPTER 13 HYDROCARBON Hydrocarbons are composed of Carbon and hydrogen. The important fuels like Petrol‚ kerosene‚ coal gas‚ CNG‚ LPG etc. are all hydrocarbons or their mixture. Sources: Petroleum and natural gas are the major sources of aliphatic hydrocarbon while coal is an important source of aromatic hydrocarbons. The oil trapped inside the rocks is known as petroleum. PETRA – ROCK‚ OLEUM – OIL. The oil in the petroleum field is covered with a gaseous mixture known as natural

density. PEM fuel cells also promise to become an alternative to batteries in portable electronics‚ such as laptop computers‚ cellular phones‚ and other hand-held devices. The catalysts currently used in PEM fuel cells are Pt nanoparticles supported on carbon black. Pt as a precious metal is expensive‚ and there have been tremendous efforts made to reduce its usage. One way is to make Pt nanoparticles as small as possible to maximize the catalyst dispersion and thus its utilization. Smaller nano particles

functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol); if bonded to three other carbons‚ it is a tertiary alcohol (eg. 2-methyl-2-propanol). Due to the placement of the hydroxyl functional group in each of the degrees of alcohol‚ the reactivity of each should
