compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two phases‚ which will allow for their separation. Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases are a solid‚ stationary phase and a liquid‚ mobile phase. The solid phase you will be using in today’s

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed

CHAPTER 6 PRETREATMENT AND CLEANING Pretreatment and cleaning are two independent processes that could also be related to each other at the same time. Such methods are crucial for seawater reverse osmosis for what they bring from cost and residence time reductions to the increase in the production quality. 6.1. Pretreatment Various pretreatment methods are used and they include: biofilter‚ subsurface intake systems‚ conventional treatment‚ biological activated carbon‚ and chlorine injection.

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

Conversion of Alcohols to Alkyl Halides Ankita Patel August 6‚ 2013 Introduction This lab consisted of the conversion of alcohols into alkyl halides through common substitution methods. These methods include SN1 and SN2 mechanism‚ both of which can occur for this type of reaction. For both reactions‚ the first step of protonation will be to add hydrogen to the –OH group and then the rest of the reaction will proceed according to the type of mechanism. SN1 reactions form a cation intermediate

Imbibition in Kidney Beans * Aim of Experiment: * To investigate the effect that emersion in salt solutions has on imbibition in kidney beans. * Safety Considerations: * One must use extreme caution when working with chemicals. Always wear protective goggles and gloves when handling them. KCl is slightly hazardous in case of skin contact‚ eye contact‚ ingestion‚ or inhalation. In case of eye contact‚ immediately flush eyes with plenty of water for at least 15 minutes. Seek
