Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared

design will be using a single central reservoir cylindrical in shape which will be stored approximately 50 feet underground. The transfer of heat to or from the central reservoir will be achieved through a piping system connected to a special Freon evaporator installed above around in conjunction with glycol working fluid media. A directional valve will be provided to reverse the movement of the refrigerant to create the heating and cooling cycles. The proposed geothermal energy system is basically

Sufficient Homemade Air Conditioner Introduction and Background of the Study As day time is starting to become more and more unbearable‚ as fans would only constantly stir the hot sticky air S around‚ so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed

PRODUCTION OF OLIVE OIL INTRODUCTION Olive oil is a pale yellow to greenish oil extracted from the fruit of the European olive tree (Olea europaea L.)‚ which originated in the Mediterranean area. The olive is originally native to the eastern Mediterranean region but the cultivated form is now grown throughout that area and in other parts of the world with Mediterranean-type climates. It hardens at refrigerator temperatures - around 10 degrees F. Today a market certainly exists for olive oil

the essential oil and bioactive compounds of this plant was obtained by macerating‚ filtrating and evaporating by using rotary evaporator. During maceration process‚ the grounded B. rotunda with its solvent has been occasional shaking to increase diffusion for more extraction yield purposes. After 4 days‚ the mixture were filtered and evaporated with rotary evaporator at 40oC. The grounded B. rotunda was extracted for thrice times. It is because an appreciable amount of active compounds may be left
