Product Description:

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.

4).HCFC-141b is flammble ,and should be stored in well-ventilated place without flame.

Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
Q:What is carbohydrate? What is organic? What is it?
Organic compounds contain hydrogen, oxygen, carbon three elements, and the proportion of hydrogen and oxygen in accordance with the composition of the water called carbohydrates. Organic matter is a compound containing carbon, but does not include carbon elements and their allotypes and carbon dioxide and carbonates. The inorganic matter is a carbon-free compound
Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong
Q:What cells are composed of compounds
Water, various inorganic salts, sugars (mainly glucose and sugar), nucleotides, amino acids, lipids
Q:What are the inorganic compounds
The inorganic compound is a compound other than an organic compound. Organic compounds are organic matter containing C (carbon), in addition to CO2, carbonated, carbonate-containing.
Q:Why not ah?
Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2
Q:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC
Q:Is it possible to understand that organic matter is contained in the heat of inorganic matter?
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:Why is the chemical name in the uncommon word so much?
China's chemical name may be the best of both Latin and English
Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?
Organic carbon can be used in various architectures (ring, chain, short or long chain, twisted or planar aromatic or heterocyclic or naphthenes containing N / S / X halogen / P, etc.) Reaction mechanism (electrophilic addition, nucleophilic substitution, carbon positive ion intermediates, etc.). Due to the large negative carbon power is not great, the number of hybrid tracks can be 2 to 4 and not too much. For silicon, because of the electronegativity is less than hydrogen, resulting in silane hydrogen bonds in the biased hydrogen to make it easy to break, so silane in the air can be spontaneous combustion (not to mention disilane and above) The formation of compounds (similar to the alkyl) between the basic and hydrogen is so unstable that other similar compounds are difficult to stabilize.
