scale while fruits of Alphonso variety are used for squash in coastal western zone. The wood is used as timber‚ and dried twigs are used for religious purposes. The mango kernel also contains about 8-10% good quality fat which can be used for saponification. Its starch is used in confectionery industry. Mango also has medicinal uses. The ripe fruit has fattening‚ diuretic and laxative properties. It helps to increase digestive capacity. Among internationally traded tropical

1.0 SUMMARY: The reactor test rig (RTR) experiment is purposely done to compare the performance of single stage CSTR‚ 3-stages CSTRs and PFR. The solutions that been used in this experiment is dilution of 0.1M of sodium hydroxide‚ NaOH and 0.1M of ethyl acetate‚ Et(Ac) to 60L. There are four common measures of reactor performance and the most important one is conversion. Then the speed is set to be at 300rpm and reading is taken every 5 minutes till the outlet conductivity remains constant. From

Another word for "fats." Lipids can be more formally defined as substances such as a fat‚ oil or wax that dissolves in alcohol but not in water. Lipids contain carbon‚ hydrogen and oxygen but have far less oxygen proportionally than carbohydrates. They are found in places as diverse as egg yolks and the human nervous system and are important component of plant‚ animal and microbial membranes A fatty or waxy are organic compound that is readily soluble in nonpolar solvent (e.g. ether)

to remove excess moisture from the clothes. Soap and laundry detergent is also used to remove the dirt from the clothes. No matter what the brand‚ all soaps function the same way. These alkali materials remove the grime through the process of saponification‚ in which the soap suspends the dirt until it becomes loose during the tumbling action of the washing machine. Other materials that are generally found in a laundry service’s establishment would include ironing equipment such as steam irons and

Synthesis of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant ------------------------------------------------- Abstract The purpose of the study is to synthesize salicylic acid from the ester‚ methyl salicylate‚ and determine the acid’s dissociation constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized‚ to ensure maximum purity‚ and filtered‚ dried‚ and weighed. The melting point
