Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

of sand was added to the top of the silica. More eluent was added and drained until it was level with the top of the sand. Extraction of pigments 3-4 baby spinach leaves were gathered and placed into a mortar with a small amount of sand. 8mL of methanol was measured out and added to the mortar. A stemmed funnel lined with a filter was clamped and placed into a 125mL separatory funnel (with stopcock closed). The spinach was crushed with a pestle until it turned a dark green

moving surfaces to reduce friction between them. E.g. Motor oil‚ Greases‚ Graphite‚ Glasses. Three different types of lubricant and the purpose they serve: Glasses: Glass is used as a Lubricant for having high viscosity. Usually glass is solid but in high temperature it becomes viscous. Viscosity is a function of temperature but not of pressure which depends on the type of glasses. In addition having poor heat conductivity makes glass useful. Glass works as a thermal bar between hot components. Usually

AIM: I am carrying out an investigation to see which alcohol is the best fuel. I will do this by experimenting with different alcohols and setting them alight and measuring different factors. I will analyse all my results and try to discover patterns‚ which should help me to conclude which alcohol is the best fuel. PLAN ==== This is how my experiment will be set out: ========================================== Keeping this experiment a fair test ===================================
