about currency symbol
value symbol is also called "currency symbol". It is a kind of currency symbol that can replace metal currency to play the function of circulation means. Notes and coins of insufficient value are symbols of value. Because money, as a means of circulation, is only a medium of transaction, which is fleeting. To get it is to give it up. Therefore, traders don't care whether the medium itself has value or not, as long as it can replace value and be accepted by others. Therefore, the paper money with unlimited solvency and coins with insufficient value endowed by law can be used as currency instead of metal currency. In the history of currency, the earliest value symbol is the devalued gold coin. At first, gold coin was the original currency, that is, its nominal value was completely consistent with its actual value

Good afternoon. Aromatic hydrocarbons, aliphatic hydrocarbons and alkanes are good solvents for organotin. Esters, ethers, alcohols and ketones can also be used for limited dilution. Mbtc is similar to the catalyst lauryl dibutyltin used for ink and paint. It can use 6 ᦇ or 120 ᦇ solvent oil (6 ᦇ is ordinary white oil for cleaning mobile phone screen). If you don't care about the smell, you can also buy a bottle of AR xylene nearby. I don't know what your dilution purpose is. If it is used as crosslinking catalyst of active monomer, it can be diluted to 1% - 3%. Mbtc and lauryl tin, stannous octanoate and other uses are similar, please refer to as appropriate
triphosgene is a white crystal with a phosgene like odor
its English name is bis (triehloromethyl) carbon or triphosgene
strong stability, only a small amount of decomposition at boiling point, resulting in trichloromethyl chloroformate and phosgene
solubility: insoluble in water, soluble in ether, THF, benzene, cyclohexane, chloroform, carbon tetrachloride, 1,2-dichloroethane, dichloromethane, ethanol and other organic solvents.
triphosgene is also known as solid gas, its chemical name is bis (Trichloromethyl) carbonate, and its English name is bis (triehloromethyl) carbonate or triphosgene
triphosgene is a white crystal with a smell similar to phosgene
molecular formula c3cl6o3
molecular weight 296.75
CAS No. 32315-10-9< The melting point is 81-83 ℃< The boiling point is 203-206 ℃< The solid density is 1.759/em3< The melting density is 1.6299/em
strong stability, only a small amount of decomposition at boiling point, resulting in trichloromethyl chloroformate and phosgene
solubility: insoluble in water, soluble in ether, THF, benzene, cyclohexane, chloroform, carbon tetrachloride, 1,2-dichloroethane, dichloromethane, ethanol and other organic solvents
one molecule solid triphosgene can be decomposed into three molecule gas phosgene. Compared with gas phosgene, it has the advantages of transportation, safe use, convenient measurement, reverse dropping reaction, and the reaction is close to equal equivalence. In instry, it is only treated as a general toxic substance. It can replace phosgene or diphosgene in medicine, pesticide, organic chemical instry and polymer synthesis
the initial decomposition temperature of solid phosgene is 130 ℃, and it begins to decompose at 90 ℃ in a humid atmosphere. It should be stored in a dry and cool place, away from fire source, and separated from organic amines
its physical properties were reported in 1887, but its crystal structure was not reported until 1971. Its crystal structure is single crystal, and its crystal parameters are a = 9.824 10-om, B = 8.87 x10-om, C = 11.245xio-om. m. The crystal angle of Triphosgene is about 91.70.
when triphosgene is distilled at atmospheric pressure, a small amount of decomposition occurs, resulting in phosgene and trichloromethyl chloroformate. Studies have shown that triphosgene can be safely quantitatively decomposed into phosgene [7J] in the presence of chloride ions, which solves the problem that phosgene can not be accurately measured in the reaction process< The reaction equation is as follows:
triphosgene was synthesized by chlorination of DMC and chlorine under the initiation of light, heat or initiator. The chlorination reaction is a free radical chain reaction, NMR study showed that chlorination was carried out step by step
uses: used for synthesis of chloroformate, isocyanate, polycarbonate and acyl chloride.
