a halogenoalkane Objective: To synthesis 2-cholo-2-methylpropane by using corresponding alcohol and HCl(aq). The reaction is via SN1 of tertiary alcohol. Techniques: i) Distillation of the reactant and the product ii) Purification by separating funnel Theory: In the experiment‚ SN1 reaction take place‚ HCl is added to initiate the reaction. The R-OH attack the H+ with the lone pair on O. Then the R-O+H2 bond breaks the release a water molecule and a carbonium ion. The Cl- will then

Background National Cranberry Cooperative (NCC) had faced operational problems at Receiving Plant #1 (RP1) during the peak harvest season in the fall of 1995‚ which had resulted in unhappiness of the owners of the Co-operatives and high labour cost‚ despite the purchase of an additional dumper. To avoid the same problems in the coming peak season‚ it is important to analyse the plant operations based on predicted demands and make recommendations if new equipment should be purchased before the fall

mixture and the flask was shaken until it dissolved. The flash was rinsed with 15 mL dichloromethane and it was added to the separating funnel. 10 mL of water was added to the funnel and shaken to mix the layers. The lower organic phase was drained into the Erlenmeyer flask and the aqueous phase out of the funnel. After that‚ the organic layer was returned to the separating funnel and washed with 15% NaCl solution. Anhydrous sodium sulfate was used as the drying agent and allowed the solution to

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

used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system‚ thus separating them. Chromatography is necessary in chemical industries‚ as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler forms) in a mixture. Example- analyte 1: analyte 2
