Medea is a tragic play written by the ancient Greek playwright Euripides, which tells the story of a woman named Medea who takes revenge on her ex-husband, Jason, and his new wife by killing their children. The play is set in Corinth, a city in ancient Greece, and it explores themes of love, loyalty, and betrayal.

Medea is a complex and multifaceted character who is driven by her deep love for her children and her desire to protect them at all costs. She is also motivated by a sense of betrayal and anger towards Jason, who has abandoned her and their children in order to marry a wealthy princess. Medea is torn between her love for her children and her desire for revenge, and ultimately chooses to take the latter path, killing her children in order to hurt Jason and his new wife.

The play explores the theme of love and its consequences, as Medea's love for her children ultimately leads her to commit a horrific act. It also delves into the theme of loyalty, as Medea must choose between her loyalty to her children and her loyalty to her husband. The play ultimately suggests that loyalty and love can sometimes be at odds with one another, and that the choices we make in the name of love can have devastating consequences.

The play also touches upon the theme of betrayal, as Jason betrays Medea by leaving her and their children for another woman. Medea's reaction to this betrayal is extreme, but it is a clear expression of the depth of her love for her children and her desire to protect them.

In conclusion, Medea is a tragic play that explores themes of love, loyalty, and betrayal. It tells the story of a woman who is torn between her love for her children and her desire for revenge, and ultimately chooses to take a violent and tragic path. The play serves as a cautionary tale about the dangers of love and the consequences of our actions.

Green Oxidation of Borneol to Camphor using Oxone

The solution was stirred andOxone 1. Table Full size table Quality loss test Measurements of the mass loss of antifouling resins were carried out and the release rate of camphor from antifouling coating was tested by using UPLC. Thesynthesis involved the use of sodium chloride as a catalyst. Google has not performed a legal analysis and makes no representation or warranty as to the accuracy of the list. Preview text Green Oxidation of Borneol to Camphor with Oxone Mercedes Erpelding TA Maetzin Cruz Chemistry 2311 Section 4 November 6, 2017 Purpose: The experiment demonstrated the oxidation of 1s -borneol to camphor. Contact angles of 4 different spots on the surface were measured and the final value of contact angle was the average of contact angles at these 4 spots. Modern approaches to marine antifouling coatings.

Seal the culture container with an aseptic sealing film with air vent on the surface. The experiment also demonstrated the efficiency, ease, and costeffectiveness of sublimation as a means of purification. Boca Raton FL : CRC Press. Three slides of each coating were used to get an average value and deviation. The by products of chromium salt from the oxidation of chromic acid have been known to be harmful to the environment and humans. However, the release rate of 3c is still slightly higher than that of other samples, although this advantage is not obvious. Sensory Characteristics of Camphor.

It has a balsamic odour type with pine, woody and camphoraceous facets. Functional polymer brushes via surface-initiated atom transfer radical graft polymerization for combating marine biofouling. Observations from the IR spectrum, H NMR Spectrum and melting point supported the conclusion that the synthesis of 1s -camphor was achieved and the reaction was successful. Therefore, there are various methods available to synthesize camphor. This study highlighted the environmentally friendly antifouling coating as a potential candidate and efficient strategy to prohibit biofouling in seawater.

The starting material 1s -borneol is a renewable feedstock because it is naturally occurring and i can be synthesized by reduction of camphor in the reverse reaction. The same experiments yielded an average yield of about 70% for the pure product1. Measurements of mass loss of antifouling resin were also carried out and the release rate of camphor from antifouling coating was tested by using UPLC. The reaction mechanism is shown below. The changes of TIPSA content have no significant effect on the release rate and antifouling performance of the resin system.

Oxidation of Borneol to Camphor Using Oxone and Catalytic Sodium Chloride: A Green Experiment for the Undergraduate Organic Chemistry Laboratory. In the second stage, compared with sample 3c, basically it continued the trend of the first stage, and the weight loss was still the lowest, which indicated that the resin might have a certain delay effect on the weight loss of coating system. Assymetric SynthesisThe Reaction of Turpentine with Oxalic Acid, and Its Application to a Camphor SynthesisI. Pacific Affairs 1932, 5, 797-801 3 Green, B. Green Oxidation of 1S -Borneol to 1S -Camphor with Oxone Scheme Mechanism: The green agent used in the experiment, oxone, oxidizes the chloride ion from the NaCl into a molecular chloride. The purpose of he experiment was to efficientlysynthesize camphor in an environmentally friendly way. The attachment area of algae is calculated by image processing software and the data of 10 points are averaged.

Standard Practure for the Preparation of Substitute Ocean Water. This procedure was repeated on day 14, 30, 48, 56, and 64. Although camphor can be easily steam-distilled from a specific tree, that tree is not always readily available. Carefully move the container into an illuminating incubator. This experiment successfully produced only environmentally benign waste by only producing excess salt in the aqueous solution, which in the end of lab was neutralized and washed with water down the drain. The sublimation caused white crystal product to be observed on the bottom of a round bottom flask and the inner walls of the beaker of the sublimation apparatus. The content of IBOMA decreased from 50% to 16.

Thepurification was made possible by the compact and symmetrical structure of camphor, resulting in itstendency to sublime when heated. Inhibition of biofilm formation on silicone rubber samples using various antimicrobial agents. Fanning 2 Scheme 1 : Possible Mechanism of Oxone and catalytic sodium chloride oxidation of borneol 1 The mechanism for the synthesis of camphor involves the oxidizer formation using chloride and Oxone to produce chlorine hydroxide and release sulfate. The Sublimation performed took advantage of camphors very low vapor pressure. Thepercent recovery from the purification was 42%. Camphor is a very eco-friendly and easily obtained compound that shows about 50% efficiency in the production of carbon nanotubes 4. As showed in Table Full size image Controlled release of camphor In order to optimize the antifouling performance of an antibiofouling system, it is necessary to study the controlled-release performance of antifoulant camphor in detail.

GC, GC-MS,1H NMR, IR, and melting point were all used to determine confirm the efficiency of the synthesis andpurification of camphor by the oxidation of borneol. Each glass slide used was weighted before and after the coating to determine the initial dry weight W 0 of each sample. Full size image Fig. This could be positively changed by involving a reaction at the end to restore the active state of the oxone. Recently, oxone has been used as an oxidizing agent which offers a safe alternative to the commonly used chromium reagents. This indicated that the proportion of TIPSA in the whole system was limited, which was not enough to change the weight loss effect of the whole system. The second green chemistry principle present in the experiment was the use of safer reagents.
