SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

IGCSE Complete Chemistry Notes Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances‚ when mixed‚ particles bounce off in all directions when they collide. This mixing process is called diffusion. It’s also the movement of particles without a force. The smallest particle

ABSTRACT: Water is omnipresent in foodstuffs and the surrounding atmosphere. In principle‚ the moisture content of a food can therefore be determined accurately by measuring the number or mass of water molecules present in a known mass of sample. It is not possible to directly measure the number of water molecules present in a sample because of the huge number of molecules involved. A number of analytical techniques commonly used to determine the moisture content of foods are based on determinations

this lab include the following: 1. Sublimation. This involves heating a solid until it passes directly from the solid phase into the gaseous phase. The reverse process‚ when the vapor goes back to the solid phase is called deposition. 2. Extraction. This uses a solvent to selectively dissolve one component of the solid mixture. With this technique‚ a soluble solid can be separated from an insoluble solid. 3. Decantation. This separates a liquid from an insoluble solid by carefully pouring

Special Report Methyl ethyl ketone – A techno-commercial profile M ethyl ethyl ketone (MEK or 2-butanone) is an organic compound with the formula CH3C(O)CH2CH3. Its CAS number is 78-93-3. The colorless liquid ketone has a sharp‚ sweet odour of butterscotch and acetone. It is produced industrially on a large scale‚ and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent. With natural and synthetic resins‚ MEK produces solutions with low viscosity
