1999 Adipic Acid (98/99-3) Currently operating commercial production processes for adipic acid depend on the production or purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA

The primary objective in the lab is to determine the molecular formula of Copper Oxide through synthesis of copper oxide. In the first procedure‚ an empty crucible‚ Bunsen Burner‚ and electronic scale were placed onto the workbench. The electronic scale was zeroed before the crucible was placed on it. The total mass of the empty crucible was 88.000g. Afterwards‚ 10 grams of copper powder was placed into the crucible and weighed to be 98.000 g. The crucible with the copper was placed onto the Bunsen

Eric McKenzie Geophysical Science Honors February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly

Determine the Activation Energy of the Reaction between Br— and BrO3— in Acid Solution S.6 ( ) Name: [ ] ( ) Time allowed: 55 minutes Introduction: The reaction can be represented by 5Br—(aq) + BrO3—(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(l) The progress of the reaction may be followed by adding a fixed amount of phenol together with some methyl red indicator. The bromine produced during the reaction reacts very rapidly with phenol. Once

Victoria MacDonald SCH3U Zegil Due May 5th‚ 2017 Magnesium Oxide Lab Purpose: To determine the composition by mass of magnesium oxide‚ the percentage composition‚ and the percentage yield. Hypothesis: The law of definite proportions states that a chemical compound always contains the same amount of proportions of elements by mass. Based on the law of definite proportions‚ the percentage composition of magnesium oxide should be 60.3% magnesium and 39.7% oxygen. Prediction: Based on the law of

Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers
