    (실험개요, 목적, 필요성 등을 서술)
    본 실험의 핵심 키워드는 saponification, acid-base titration, rate constant, rate law 등이 있다. 구체적으로 CSTR에서 수산화나트륨(NaOH)과 초산에틸(Ethyl Acetate)의 비누화 반응을 진행한다. 반응 완결 후 titration을 통해 rate constant, rate law를 계산한다. 또한, reaction temperature를 다르게 하여 Arrhenius equation을 통해 반응의 activation energy와 pre-exponential factor(혹은 frequency factor)를 구한다. Chemical reactor를 operating 하는데, 엔지니어로서 화학 반응에 대한 이해는 필수불가결하다. 본 실험을 수행함으로 위에서 언급했던 키워드 이외 실제 CSTR을 operating 해보며 화학공학 엔지니어로의 첫걸음을 내딛을 수 있다.

    2.실험방법
    (1) 0.1M의 NaOH를 제조하기 위해 필요한 NaOH의 무게를 계산한다.
    ※ 우리는 NaOH 8.25g을 사용했으며 계산과정은 3. 실험 결과에 작성하였다.

    (1)번 과정에서 계산한 양을 저울을 이용해 양을 잰 뒤, 증류수가 들어있는 용기에 넣는다

    • 1. saponification
      Saponification is a fundamental chemical reaction in which a fat or oil is reacted with a strong base, such as sodium hydroxide or potassium hydroxide, to produce glycerol and a salt of a fatty acid, commonly known as soap. This process is widely used in the production of various soap products, including bar soaps, liquid soaps, and detergents. The saponification reaction is an important topic in chemistry as it demonstrates the principles of acid-base chemistry, organic reactions, and the production of useful consumer products. Understanding the mechanism and factors that influence the saponification reaction, such as the choice of reactants, reaction conditions, and the properties of the resulting soap, is crucial for both academic and industrial applications. The study of saponification provides valuable insights into the chemical properties of fats and oils, the behavior of organic compounds in the presence of strong bases, and the practical applications of these reactions in the manufacturing of personal care and cleaning products.
    • 2. acid-base titration
      Acid-base titration is a fundamental analytical technique in chemistry that is used to determine the concentration of an unknown acid or base solution by reacting it with a standardized solution of a known concentration. This process involves the gradual addition of one solution to another until the reaction is complete, as indicated by a change in the pH or color of the solution. Acid-base titrations are widely used in various fields, including analytical chemistry, environmental science, and pharmaceutical analysis, to quantify the amount of a specific substance in a sample. Understanding the principles of acid-base equilibria, the selection of appropriate indicators, and the interpretation of titration curves is crucial for accurate and reliable results. The study of acid-base titrations not only provides valuable insights into the behavior of acids and bases but also develops essential skills in experimental design, data analysis, and problem-solving, which are highly applicable in both academic and professional settings.
    • 3. rate constant
      The rate constant is a fundamental parameter in chemical kinetics that quantifies the speed or rate at which a chemical reaction occurs. It is a measure of the probability of a successful collision between reactant molecules, leading to the formation of products. The rate constant is influenced by various factors, such as temperature, pressure, the presence of catalysts, and the nature of the reactants. Understanding the rate constant and its relationship to other kinetic parameters, such as the reaction order and the activation energy, is crucial for predicting the progress and outcome of chemical reactions. The study of rate constants is essential in fields like organic chemistry, biochemistry, and chemical engineering, where the optimization of reaction conditions and the development of efficient catalysts are of paramount importance. Mastering the concept of rate constants and the factors that affect them enables chemists to design and control chemical processes more effectively, leading to improved efficiency, productivity, and sustainability in various industries.
    • 4. rate law
      The rate law is a mathematical expression that describes the relationship between the rate of a chemical reaction and the concentrations of the reactants. It is a fundamental concept in chemical kinetics that allows for the prediction and analysis of the progress of a reaction over time. The rate law typically takes the form of a power function, where the rate is proportional to the concentrations of the reactants raised to specific exponents, known as the reaction orders. Understanding the rate law and its components, such as the rate constant and the reaction orders, is crucial for understanding the mechanism of a chemical reaction, designing experiments to determine the rate law, and predicting the behavior of complex chemical systems. The study of rate laws is essential in fields like organic chemistry, biochemistry, and chemical engineering, where the optimization of reaction conditions, the development of catalysts, and the prediction of product yields are of great importance. Mastering the concept of rate laws enables chemists to design and control chemical processes more effectively, leading to improved efficiency, productivity, and sustainability in various industries.
    • 5. CSTR
      A Continuous Stirred-Tank Reactor (CSTR) is a type of reactor commonly used in chemical engineering and industrial processes. It is characterized by the continuous flow of reactants into the reactor, where they are thoroughly mixed and undergo a chemical reaction, and the continuous removal of the resulting products. The CSTR is a well-mixed system, meaning that the composition and properties of the fluid within the reactor are uniform throughout. This uniform mixing is achieved through the use of an agitator or impeller, which ensures efficient mass and heat transfer within the reactor. The CSTR is widely used in a variety of industries, including chemical, petrochemical, and pharmaceutical, due to its ability to maintain a constant product composition and its suitability for reactions that require good mixing and temperature control. Understanding the principles of CSTR design, operation, and analysis is crucial for chemical engineers and process scientists to optimize the performance of these reactors, improve product quality, and ensure the safety and efficiency of industrial processes. The study of CSTRs provides valuable insights into the fundamental concepts of chemical reaction engineering, fluid dynamics, and process control, which are essential for the development and optimization of various chemical and industrial systems.
