Stearic Acid Powder

Q: Is carbon monoxide an organic gas?: Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.

Q: Simply talk about hydrocarbons: Hydrocarbon oil is a substitute for petrochemical diesel bio-liquid fuel, is a substitute for oil energy. It is a kind of liquid fuel produced by the lipid exchange reaction under the action of the catalyst, which is made of various kinds of lipid compounds (rapeseed oil, cottonseed oil and various vegetable oil waste) and methanol as raw materials. Burning, no black smoke, no smell, no harmful gas discharge. After testing the physical and chemical indicators have reached the national standard. Is a renewable energy source of biomass, the required wide range of raw materials, cheap.

Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).: Understand enough messy

Q: Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid: In the carbonyl R-COOH carbon, one of the O can only form a double bond with C, that is, a sigma bond and a Pi bond, and also with R and OH each form a sigma key, a total of four keys, C on the most The outer layer and no electrons to form solitary electrons. According to the principle of hybrid, because there are only three sigma, need to participate in the hybrid track can only be three, that is, sp2 hybrid.

Q: What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?: Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.

Q: How to do it? Solve Inorganic Chemistry: Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization

Q: Organic intermediates in the synthesis, what is the chemical choice: Choose the first reaction that is easy to react quickly

Q: Organic chemistry, carboxylic acid derivatives are not acid?: According to acid-base ionization theory and proton theory, not; according to acid-base theory, some is

Q: How to distinguish between inorganic chemicals and organic chemicals: Organic chemicals is probably the organic, organic concept you can see Encyclopedia details

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Stable, then it will not be 60 degrees that is broken down, there is no need for rectal administration ... ...
