INTRODUCTION TO BAMBOO CHARCOAL Bamboo charcoal is made up from pieces of bamboo‚ which are taken from plants three to four years old‚ and burned inside an oven at temperatures over 800° C. It not only provides a new way to utilize bamboo‚ but also benefits to environment protection by reducing the residues pollution. Bamboo charcoal is an environmentally functional material which has excellent absorption properties. Bamboo charcoal is made of bamboo by pyrolysis process. According to the types

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation. An examination of the porphyrin structure

Abstract Acetaldehyde is produced throughout the world primarily from ethylene‚ although some is still derived from ethanol and acetylene. Demand for acetaldehyde worldwide has continued to decrease primarily as a result of less consumption for acetic acid manufacture‚ as the industry continues to move toward the more efficient and lower-overall-cost carbonylation-of-methanol process. For example‚ all manufacture of acetic acid from acetaldehyde in North America has been discontinued and in

Karmini Mondal Chemistry 245- 061 Biosynthesis of Ethanol from Sucrose Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g
