Introduction The purpose to of this experiment is to carry out the alkylation of sodium saccharin with iodo-ethane and analyze the product mixture to determine the structure of the major product. Sodium saccharin is made from the base catalyzed de protonation of saccharin. This nucleophilic reaction is special because the nucleophilic atom can be oxygen or nitrogen and the leaving group is iodide ion. The solvent used in this reaction is very important for determining the rate of nucleophilic

(Bhasin‚ 2012). Among over 150 basil species belonging to the genus Ocimum‚ two most widely grown species for essential oil production are holy basil (Ocimum sanctum L.) and sweet basil (Ocimum basilicum L.). Ocimum basilicum‚ an erect highly branched aromatic perennial herb of family Lamiaceae is well known for its sweet basil oil and is widely distributed throughout India. This species is believed to be originated in India and some neighbouring countries. In the plains of north India‚ south India and

and taste sodium benzoate‚ then any potential link between those traits could never be established by this experiment‚ as all of the data that would have connected those traits would have been mixed in with other information from other students. To keep that from happening in future experiments‚ each student should mark what they tasted on independent charts‚ so as to allow the data to be interpreted more closely. There were some inconsistencies in the data. In the sodium benzoate testing‚ there were

composed of sucrose (10%)‚ aspirin (40%)‚ and Tylenol (50%). Although this information is reported‚ the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification of the unknown component‚ as well as the true percent composition of each component of Panacetin. This experiment involves two parts‚ covering

Aromatic hydrocarbon was presence in both sample petrol and unknown. Alkanes hydrocarbon was presence in other sample. Objective The objectives of this experiment are to perform sample preparation by SPME and to identify the components of hydrocarbon

CHAPTER II RELATED LITERATURE Blumea balsamifera(sambong) A Phytochemical and Pharmacological Review Sambong (Blumea balsamifera) is a native flowering or weed that is endemic in the Philippines and other tropical countries. It is a popular herb especially for its healing properties including antidiarrhetic‚ antigastralgic‚ expectorant‚ stomachic‚ and antispasmodic‚ among others. Aside from these‚ sambong is also popular for being emmenagogues‚ or for stimulating menstruation or the blood flow
