Commonly used devices for organic chemistry experiments
In order to facilitate access and comparison of the basic operations commonly performed in organic chemistry experiments, Rebaud Intermediate Research Center concentrates here on the instrumentation for reflux, distillation, gas absorption and stirring operations.
The use of common laboratory glassware and the use of specifications
The most contacted and used glass instruments in the laboratory is the most, if the correct cleaning and maintenance of glass instruments? (1) After washing the glass instruments upside down when the wall should not hang water beads, and then use a small amount of distilled water or deionized water to shabu-shabu several times. (2) glass instruments to pay attention to the use of a variety of different nature of the washing solution, be sure to remove the previous washing solution before using the next washing solution to avoid mutual influence. (3) Measurements of standard substances or samples of glass instruments can not be used to dry at high temperatures, should be inverted to dry.
Common analytical classifications in analytical chemistry and their principles
Today we will learn together the common analytical classifications and their principles in analytical chemistry. So, first let's understand what analytical chemistry is. Analytical chemistry is the study of obtaining information about the chemical composition and structure of substances, analytical methods and related theories. It addresses the problems of determining which components are contained in a substance, how these components are present in the substance, what the relative content of each component is, and how to characterize the chemical structure of a substance.
How to protect yourself while working in organic synthesis
First of all; do not be paralyzed! Do not think that this organic material toxicity is small can be negligent, because some toxic substances can accumulate over time! If you want to engage in this work for a long time it is best to minimize the opportunity to contact with them, so in the laboratory to pay attention to the following points.
