Aplication
A long-term non-ozone depleting replacement for R-502 and R-22 in low- and medium-temperature commerical refrigeration systems.R404A is made up of the components HFC125,HFC143a and HFC134a.The stability of R404A can be characterized based on the stability of its refrigerant components,in this case,by the known stability of R134a.
Retrofit:
R404A can be used to retrofit many existing R502 systems. The physical and thermodynamic properties of the blend cause it to behave much like R502 when used as a retrofit but it is not intended to be a direct “dropin” for R502 systems. Due to higher operating pressures associated with the use of R404A as opposed to R502, OEM product specific retrofit recommendations should be consulted for any and all pressure relief modifications and/or requirements.
- Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.
- Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
- The covalent compound is a compound molecule composed of a common electron pair between atoms. When two nonmetallic elements (or inactive metal and nonmetallic elements) are combined, one or more electrons are formed between the atoms, and the electron pair is attracted by two nuclei, and the two atoms are common , So that two atoms form compound molecules. For example, hydrogen chloride is a hydrogen atom and chlorine atoms each with the outermost layer of electrons to form a common pair of compounds composed of compounds. Non-metallic hydrides (such as HCl, H2O, NH3, etc.), non-metallic oxides (such as CO2, SO3, etc.), anhydrous acids (such as H2SO4, HNO3, etc.), most organic compounds (such as methane, Are covalent compounds. Most covalent compounds in the soli
- Q: Is carbon monoxide an organic gas?
- The organic compound contains carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen, etc. Any kind of organic compounds, its molecular composition contains carbon, the vast majority also contains hydrogen Elements. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, resulting in a lot of other organic compounds, so modern people generally believe that hydrocarbons and their derivatives known as organic compounds, referred to as organic matter.
- 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?
- The traditional FT synthesis method of the product of heavy hydrocarbon content is high, the composition is complex, so the combustion efficiency is not optimistic. Germany is in view of the supply of oil is less than consumption (loss of production areas and lack of refined production capacity) was forced to take the FT technology to add (Germany's local coal reserves larger). So the FT fuel in the World War II Germany's energy system accounted for little, the specific data is still controversial, there are 15% and 25% said.
- Q: Is not organic matter must not hydrogen ah?
- Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
- Q: The role of aromatic hydrocarbons
- Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
- Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
- Benzene is a hydrocarbon that is also the simplest aromatics
- Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
- Other hydrocarbon derivatives are not necessarily, such as halogenated hydrocarbons containing odd halogen molecules, containing an odd number of N atoms containing C, H. O, N four elements of the compound, their number of hydrogen atoms are odd.
- 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 ... ...
- Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
- Is a hydrocarbon derivative.
