accomplish the task? What techniques were used to purify and identify the product(s) of the reaction? In this experiment, an acid-base extraction was done to separate a mixture of an unknown acid and fluorene, a neutral compound. The possible unknown acids were 2-chlorobenzoic acid, 3-chlorobenzoic acid, and 3-methylbenzoic acid. The purification of the isolated unknown acid was performed by recrystallization and its identity was established by analyzing the melting point range of the pure product
unknown liquid compounds and one mixture of two unknown solid compounds were separated, isolated, purified, and characterized by boiling point. Two liquid unknowns were separated, isolated, and purified via simple distillation. Then, the process of an acid-base extraction and washing were used to separate two unknown compounds into two crude compounds: an organic acid and a neutral organic compound. Each crude compound was purified by recrystallization, resulting in a carboxylic acid (RCO2H) and a
Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined
to serve as internal messengers for the plant host, releasing chemicals to aid in allelopathy, to serve as defense compounds against insects and animals, and to protect the plant with their antiviral, antibacterial and antifungal properties (9). A typical essential oil is often comprised of more than 100 different chemical compounds and depending on its combination of the compounds have a broad biological and antimicrobial activity spectrum (2). The chemistry of an essential oil can be complex,
that harm such a balanced environment can potentially destroy thousands of organisms that live there. Since phosphates are common pollutants of lakes, in this project I investigate the effect of phosphates on the growth of aquatic plants. a. Objectives My objectives are to determine the effects of different amount of phosphate on the growth of aquatic plants, to know if it can damage the growth of aquatic plants to the ecosystem and to identify whether using different amount
& F2b) SABALDICCA, VENZ (F2c & F2d) INTRODUCTION Lipids are organic compounds found in living organisms that are insoluble or slightly soluble in water but soluble in non-polar organic solvents. Lipids can be classified into four groups which are -fats, oils, and waxes, -compound lipids, -steroids, and -derived lipids. Various experiments are done on lipids. Some tests are for saturation, presence of certain compounds, or for the different chemical reactions that lipids undergo. Lipids

chain compound, also of anhydroglucose units. Because plastics are made of polymers, starch is a very favorable raw material in plastic-making. The study was limited to one species of cassava, Manihot esculenta. The plastic produced was treated with different amounts of starch, polyvinyl alcohol (binder), epoxidized soya bean oil (stabilizer), and glycerol(plasticizer). The finished product was expected to be comparable to commercial plastics in terms of clarity, reaction to acids and bases, water
burning oil, kerosene and paraffin oil and, and the other 40% can be used for another purpose, such as lubrication. In the nineteenth century, the United States and Russia were the countries that produced oil which led to many developments in oil extraction. In the twentieth century, different regions in the world started to produce oil productions, such as Indonesia, Mexico and Middle Eastern countries. Since then, the oil industry has grown by more technological research and developments in improving
desireable.2 Extraction: The process of extracting Camptothecin from Camptotheca acuminate leaves (as this is where the highest concentration of Camptothecin resides) is achieved by using homogenate extraction therapy. Originally the majority of the common extraction processes were used to extract CPT, including reflux extraction, shaking extraction and ultrasonic extraction, however these methods lacked time efficiency and also produced a low yield of CPT.(5) In one particular extraction process carried
