1.Properties and Applications:
is a colorless and transparent liquid at room temperature.It has low ODP value and excellent chemical stability.Since its physical and chemical properties are similar to those of CFC-11,CFC-113,it can substitute CFC-11 as foaming agent for rigid or soft PU foam ,or CFC-113 as metal cleaner and solder -remover as well.
It has following characteristics:
1).Chemical Stability: It is stable while stored at roon temperature and will not decompose.
2).It can dissolve in most organic solvents, alcohol and ether.It has excellent compatibiity with grease and lubricant ,and no abvious effects on most polymers including plastic an rubbers.
3).HCFC-141b is not irritate to human skin and eyes ,but inhale HCFC-141b of high concetration eill cause anesthesia.

- Q:NH4HCO3 and so have C atoms ah, why still inorganic
- Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.
- 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:Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on
- hydrocarbon
- Q:What are the characteristics of organic compounds?
- Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
- 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).
- Inorganic matter with carbon after, as if with their own ideas, began to build their own. So slowly evolved into a complex organic matter
- Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
- The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
- Q:How the most primitive life on earth is produced under what conditions
- These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
- Q:What is the difference between organic matter and inorganic matter?
- Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.
- Q:Compare the difference between London smoke and Los Angeles photochemical smog
- Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
- Q:Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- Organic matter is an abbreviation for organic compounds. At present, human beings know more than 900 million kinds of organic matter, the number is far more than inorganic.
