Essential oils are volatile components associated with the aromas of seeds‚ bark‚ or roots of plants. In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation

Crude‚ a documentary by Joe Berlinger‚ provides an eye-opening look into the highly controversial battle between Texaco and the Amazon Jungle of Ecuador. The film follows the lawyers’s fight to improve the jungle’s living environment and restore the original beauty of the Amazon. Texaco has been contaminating the rainforest for around three decades‚ poisoning the water‚ air and land. The pollution has created a ‘death zone’ that has been increasing the rates of cancer‚ leukemia‚ birth defects‚ and

This also includes various oil reserves that were found in the year of 1964 along with the Texaco Company that is completely controlled by another company known as Texaco Petroleum Company. This was given by the government to inquire into oil production‚ which is in the region along with a partnership that is done with the government.

Distillation of Alcoholic Beverages Pamela Mallari*‚ Symon Manuel‚ Katherine Merene and Charlene Mondelo Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Distillation is a physical process used to separate chemicals from a mixture by the difference in how easily they vaporize. This experiment aims to (1) compare the efficiency of simple and fractional distillation‚ (2) distill and calculate the % of ethanol and (3) determine the % loss in distillation. Two

Comparing between the simple and fractional distillation‚ the fractional distillations for both n-propanol and acetone provided a better distillation. The data and graphs support the statement since the fractional graphs provided a steeper slope than the simple distillation. The steeper slope represent how fast the mixture are separated throughout the distillations. For example‚ the simple distillation for acetone the slope initially started at about 20 mL at about 65.5℃ and ended at about 30 mL

Car vs. A Crude Awakening: The Oil Crash Who Killed the Electric Car directed by Chris Paine and A Crude Awakening: The Oil Crash directed by Basil Gelpke and Ray McCormack are similar documentary films in several aspects including their target audiences and viewpoints. Both documentaries choose to approach their messages differently concerning their use(s) of pathos‚ logos‚ and ethos. Who Killed the Electric Car relies much more on the use of pathos to relay its argument‚ while A Crude Awakening:

CRUDE OIL REFINING OR PETROLEUM PRODUCTS IMPORTATION: WHICH IS ECONOMICAL FOR NIGERIA? ABSTRACT: One of the most crucial challenges facing Nigeria is being able to meet the energy need of the energy hungry populace; the exponential population growth makes it even more challenging. The approach adopted to meeting this need has impacted severely on the economy of the nation as reflected in the year-on-year economic figures. This can be attributed to her choice of net importer
