can assure consumers that they will be drinking safe‚ non-chemical added water. Additionally‚ distillation removes potentially harmful contaminants and does not contain any pathogens. In the article “Why You Should Drink Distilled Water” Dr. David Williams explains that as the process is ongoing pathogens are being killed. He states‚ “The boiling action kills bacteria and other pathogens‚ and as the steam rises‚ it leaves behind waste material‚ minerals‚ heavy metals‚ and other heavier contaminants”

additives will react when mixed. Both waters are purified water. Neither is ideal as a drinking water. If choosing one over the other‚ the non-drinking use must be the primary consideration. Distilled Water The most common forms of water distillation involve cooking a source water (usually tap water) to produce a water vapour. This water vapour is captured and cooled to form a condensate. The condensate is distilled water. This process separates out pure water from disinfectants in tap water

to benzene [71-43-2] to form cumene [98-82-8]‚ which is then oxidized by air to cumene hydroperoxide‚ and cleaved in the presence of an acid catalyst like zeolite. Phenol [108-95-2] and acetone [67-64-1] produced in the process are recovered by distillation. Ratio of phenol to acetone is 1:0.6. (2) By Dehydrogenation of 2-proponal The hydration of propene [115-07-1] gives 2-propanol [67-63-0]‚ which is then dehydrogenated to acetone.

2. From the plots of the boiling point versus the volume of distillate in the simple distillation experiments‚ what can you conclude about the purity of your product? Product not very pure. No distinct line to know when one begins and one ends. Distillation of cyclohexane and toluene crossed over into the other’s range. Would need to perform more distillations to better purify the solvents. 5. What is the effect on the boiling point of a solution (e.g. water) produced by a soluble non-volatile

unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found

At the same time‚ another 80% of the CPO is pumped through another plate heat exchanger (PHE) and steam heater to increase the CPO temperature to 90 – 130°C (it is a desired temperature for the reaction between CPO and phosphoric acid). Then‚ the CPO feed is pumped to static mixers and the phosphoric acid is dosed at 0.35 – 0.45 kg/ton. Inside there
