Polymerization can be divided into the two types of reactions, such as chain-growth and step-growth polymerization. Cationic polymerization is the step-growth type of polymerization. Otherwise, it is called as addition polymerization since the reaction requires addition of the substance of a certain initiator or a catalyst. In the cationic polymerization, the catalyst is cationic and it transfers the charge to the monomer in reac-tion. Cationic polymerization of biological oils occurs in presence of superacids. The re-search under consideration is going to study the process of cationic polymerization in the soybean oil with the help of the superacids as the catalyst.
This type of polymerization is not widespread in industry and therefore the mech-anism of such reaction has not been studied in detail (16). The purpose of the current re-search is to investigate how the process of cationic polymerization in the vegetable oils occurs. Soybean oil is taken as the resource for the research since it has around 4.6 double bonds / triglyceride that make it potentially polymerizable. It is suggested that the re-action under consideration may involve conjugation of double bonds in polyunsaturated fatty acids (linoleic and linolenic).
Ene reactions also supposedly may be faced in the process of reaction. The pas-sage of the ene reaction in the soybean oil is not a new phenomenon as it was reported in the experiment of Biswas et al. (23). The occurrence of the crosslinking ene reactions in the soybean oil, which was mixed with diethyl azodicarboxylate at the average room temperature, was the outcome of the experiment. It is suggested that ene reactions also can occur during the process of polymerization of the soybean oil with the superacids...

... distinguish the properties such as weight. In the research under consideration the identification, quantification, and purifi-cation of the necessary compounds can be performed. The method is able to determine polymerized triglycerides in the vegetable oils (29) and thus it is highly beneficial for the research. Liquid chromatography is applicable in the variety of the practical spheres, such as medicine and legal study, so it has high reliability.
The discussed methods are of high value for the research’s outcome. With the combination of the analyses of different type, the process of formation of the oligomers in polymerized oils can be analyzed. The products of splitting will be analyzed during the research and the methods of linking of the triglyceride units in the polymerized oils will be studied. The conclusions will be based upon the empirical investigation.

Click Chemistry Reaction Types Essay

- Click chemistry was created by taking cues from how nature naturally reacts. 1 The goal of Sharpless and colleagues was to create a number of selective blocks that could be connected in many different ways with the ability to work in many various applications. 1 For a reaction to be defined as click chemistry: “the reaction must be modular, wide in scope, give very high yields, and generate only inoffensive by products that can be easily removed” and it must have undemanding reaction conditions....   [tags: nucleophilic opening of rings, cycloaddition]

Chemical Reactions Essay

- Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances during combustion....   [tags: science]

Essay Radiation Pressure Effect on Polymerization Reactions

- A laser trap, or an optical trap, is created by tightly focusing a laser beam with an objective lens of high numerical aperture (NA).1 The trap is formed at the focal point of the objective, which is able to hold a small particle at its center. In other words, a dielectric particle near the focus will experience a force due to the transfer of momentum from the scattering of incident photons. The resulting optical force has two components: a scattering force in the direction of light propagation and a gradient force in the direction of the spatial light gradient....   [tags: Laser Beams, Chemistry, Molecules]

Polymerization of Soybean Oil with Superacids Essay

- Polymerization of oil has been reviewed in different sources of literature, since it has various theoretical aspects as well as the practical applications. Ionescu and Petrović discussed the process of polymerization of oils in the work Soybean - Applications and Technology: Polymerization of Soybean Oil with Superacids. They proving that polymer-ization of oil can be carried out at the temperature of 90 °C. In the work, it is stated that soybeans have great economic importance and thus the processes of polymerization, which can be conducted with lower energetic expenses, are crucial to investigate (13)....   [tags: dimer acids, dimer esters]

Reaction Rates Of Chemical Reactions Essay

- Introduction Kinetics is the discovery and study of the reaction rates of chemical reactions. These reaction rates involve the pace or rate at which a reaction progresses. Many specific conditions can affect the reaction rate value; furthermore, the factors include the concentration of the reactants, the polarity of the solvent, and temperature1. The rate of reaction can be determined and studied using a rate law, an equation that correlates the rate with concentrations and a rate constant. This experiment’s reaction involving t-butyl chloride has a first order reaction rate, which means that the reaction’s rate law equation is the first order equation shown below....   [tags: Chemical reaction, Chemical kinetics]

The two compounds used were Magnesium Hydroxide and Citric Acid. Both compounds were in there solid states in powder form. Magnesium Hydroxide was mixed with water and the change in heat was measured using a thermometer. The next reaction combined citric acid and magnesium hydroxide in water. The change in heat was measured as well. For the third reaction citric acid was placed in water to measure the change in heat....   [tags: Energy, Chemical reaction, Temperature, Chemistry]

ROP Mechanism: Cyclic Ester Polymerization by Tin(II) Octoate Essay

- Introduction Polymerization of cyclic esters has attracted a lot of interest for the synthesis of biodegradabale/ biocompatible polymeric materials, such as polylactide, polyglycolide and also other polymer compound such as linear polycarbonate. Ring opening polymerization of cyclic ester compounds is better than step polymerization for obtaining high Mw polymers in a controlled “living” fashion, while avoiding the formation of by-products. Tin octoate (tin(II) bis(2-ethyl hexanoate)), Sn(Oct)2) is one of the most used initiator in the polymerization of cyclic esters....   [tags: Research Analysis]

- Lab Report Kinetics of Chemical Reactions Kinetics of chemical reactions is how fast a reaction occurs and determining how the presence of reactants affects reaction rates. In this experiment the rate of reaction for Fe+3 and I- is determined. Because the rate of chemical reactions relates directly to concentration of reactants, the rate law is used to find the rate constant, and calculated with specified temperatures.
