— The decline in the use of artificial colourants due to their toxicity in food and textile industry, put forward by international market has increased the importance of natural raw materials. From those, peanut pod (Arachis hypogaea) with solid applications is one of the most important sources of natural dyes. The major colouring component in peanut is pods, extracted from the fresh and dried peanut pod. The aim of present work is to evaluate peanut pod powder as natural textile dyestuff. The work consists of three steps, i.e. extraction, characterization and dyeing processes. The dye extraction procedure is conventional and traditional. Dyeing of cotton fabrics with the extract of peanut pod powder has been carried out and dyeing has been optimized using three mordanting agents as: Alum, Copper Sulphate and Ferrous Sulphate. Finally, dyed fabric have been subjected to different textile laboratory tests e.g., colour fastness, light fastness, washing fastness and rubbing fastness (dry and wet).

It also causes severe digestive and respiratory tract burns. Keep goggles on at all times. You may want to use gloves as well. Some properties of solutions do not depend on the nature of the solute: they only depend on the number of solute particles (ions or molecules) relative to the number of solvent particles. We call these properties colligative properties. In these experiments we will focus on one particular colligative property, the freezing point depression. It has been observed that the freezing point of a solution (solvent and non- volatile solute) is lower than the freezing point of the pure solvent. Quantitatively, for a solute that is not an electrolyte, the lowering of the freezing point is described by the following equation: where ΔTf represents the lowering of the freezing point (Tf), m stands for the molality of the solution and Kf is the molal freezing point depression constant that depends only on the solvent. When the solute is an electrolyte it is necessary to include the van’t Hoff i factor in the equation (more about this later) The plot below represents a typical cooling curve of a pure solvent. It illustrates a very common phenomenon, supercooling, where the temperature of the solvent gets lower than its freezing point. This can be avoided by careful stirring of the liquid. ΔTf = Kf x m Background Cooling curve (pure substance) Safety Hazards BC Chemistry 162 Laboratory Manual Name__________________________ Section______ Page 2 of 10 The next plot illustrates a standard cooling curve for a solution. Besides the phenomenon of supercooling one notices that the freezing temperature changes with time (see the slope of the line CB). A solution does not have a sharply defined freezing point. This is because as the solvent freezes, solvent molecules are removed from the liquid and deposited on the solid, changing the con.

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment.
