On the other hand, from a structural point of view but also to clarify the various chemical and chemical properties of macroscopic materials (including chemical reactivity) and a variety of macroscopic non-chemical properties (including various physical properties of a number of new technologies and applications, technical performance, etc.) the relationship between microstructure and its regularity. On this basis, it is possible to continue to use the known laws of isopropyl alcohol, trying to synthesize a more innovative, more unusual structural features new material quality of isopropanol in the chemical bonds of combining theoretical and experimental chemical process creation of a new theory of structural chemistry. At the same time, but also continue to strive to establish a new physical substance to clarify the microscopic structure and chemistry of the experimental method. Like other branches of chemistry, structural chemistry generally from macro to micro, from static to dynamic, from qualitative to quantitative variety of different levels to understand the objective of chemicals. Deductive and inductive thinking remains a fundamental structural chemistry research. Knowledge of the chemical structure of the material can be said about the early composition and chemical properties of the elements for the study material from. At that time people of chemical substances (several compounds including elemental and one of the few), only from the understanding of the laws of the substance, such as scaling law, Law of multiple proportions, etc. to be summarized. With the determination of the chemical reaction equivalent, people put forward the concept of "valence" and for describing the laws of matter. Then, for the synthesis of molecules causes atoms and atomic arrangement in the molecule can be said to be ignorant of the way. Nigeria made a metal frog leg muscles shrink to make "animal electricity" phenomenon is generally believed that this is the origin of electrochemistry. 1799 Volta Galvani work on the basis of the invention of the "stack" of isopropanol offer different metal composition of wet paper holder that nowadays called "voltaic pile." This is the prototype of chemical power. Before the invention DC Beijing isopropanol, various chemical supply is only able to provide a constant current power supply stable. 1834 discovery of Faraday's law of electrolysis for the electrochemical laid a quantitative basis. 19 th century, Helmholtz and Gibbs work assigned battery "from the power" (now called "EMF") to clarify the meaning of thermodynamics; 1889 Nernst derived using thermodynamics involved in the electrode relationship with the electrode potential substance concentration of the reaction, known Nernst equation; 1923 Debye and Huckel made strong electrostatic dilute electrolyte solutions generally accepted theory, greatly contributed to the electrochemistry in theoretical and experimental methods development of. Beijing Baoding isopropanol isopropanol _ _ Xiang dry chemical (View) provided by the Jinan Chemical Co., Ltd., Cheung dry. Jinan Cheung Dry Chemical Co. (www.xiangqianhuagong.com) (www.dilunyierchun.com) is a professional, "glycol" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "chemical universe" brand has a good reputation.
