B) For Purification: Thitima Sarachat et al (2009) worked on Pseudomonas aeruginosa SP4 and cultivated to produce a rhamnolipid biosurfactant from a nutrient broth with palm oil. The foam fractionation technique in batch mode was used for the recovery of the excreted biosurfactant from the free-cell culture medium. The effects of air flow rate, initial foam height, the pore size of the sintered glass disk, initial liquid volume, and operation time on the process performance were studied. The results

Steam Distillation is the process of distilling a mixture wherein one of the immiscible phases is a steam. It is a mild method for separating and purifying volatile liquid or solid organic compounds that are immiscible or insoluble in water. This technique is not applicable to substances that react with water, decompose on prolonged contact with steam or hot water, or have a vapor pressure of less than about 5 torr at 100°C. One way to perform steam distillation is through the live steam method

Tetraphenylcyclopentadienone Introduction The purpose of this experiment was to synthesize tetraphenylcyclopentadienone by reacting dibenzyl ketone with benzil in the presence of a base. The reaction proceeded via an aldol condensation reaction with dehydration, and then the product crystals were isolated by vacuum filtrations using a Buchner funnel. Experiment Scheme Equation 1. Aldol condensation reaction between benzil and dibenzyl ketone in the presence of a base To begin the experiment

Mass-Mass Relationships Observations: 1. 2.8g of zinc acetate was added to a clean 250ml beaker 2. 50ml of distill water was added and the zinc acetate dissolved 3. 4.0g of sodium phosphate was added to a clean 150ml beaker and 50ml of distilled water was added. The solution was stirred until dissolved 4. I then poured the sodium phosphate solution into the beaker containing the zinc acetate solution. A white precipitate of zinc phosphate was formed in the beaker. 5. I then

4500–NH3 H. Prior to analysis, ammonia is buffered to pH 9.5 and distilled into a solution of boric acid. Cyanate, which may be encountered in certain industrial effluents, hydrolyzes to some extent, even at the pH of 9.5 at which distillation is carried out. #Distillation - adding excess base to the acid digestion mixture to convert NH4+ to NH3, followed by boiling and condensation of the NH3 gas in a receiving solution. #Titration - to quantify the amount of ammonia in the receiving solution.

4.3.2.3.2 Simultaneous Injection Two channel technique: The two channel method, developed by Battenfeld in the mid-1970s, includes a phase of simultaneous injection. The process sequence can vary but a typical example would be: • Injection of skin to a pre-set switch point • Injection of core material begins so both skin and core flow together • Injection of just core • Injection of just skin • Part packing and cooling followed by ejection. This co-injection moulding process entails the injection

A number of things affect the soap-making process and the quality of this soap produced. The characteristics of this soap depend on the quality of oil, and the amounts of the caustic soda and water used to make it. The speed of the reaction between the oil and the caustic soda is influenced by free fatty acid content of the oil, the heat of the components before mixing, and how vigorously the mixing is to be done. Free fatty acid contents, vigorous mixing, and heat, speed up the given soap-making

more detailed information and insight in that proposal. History of Absolut Distilled for the first time as Absolut Rent Branvin (or Absolute Pure Vodka) in 1879 by Swedish entrepreneur Lars Olsson Smith and produced using a revolutionary new distillation method. The method was called rectification, a method we still use today. For years to come Lars Olsson Smith was engaged in a trade war against the state and the city of Stockholm because of the monopoly of distilled spirits. He opened a shop
