BIS TRICHLORO METHYL CARBONATE

Specifications: APPEARANCE:WHITE CRYSTALASSAY: 99% MIN. ODOR: IRRITATING ODOR BOILING POINT:203-206 MELTING POINT:79-81 LOSS ON DRY: 0.1% MAX. Concrete Application Methods of BTC: It depends on concrete reaction system. Generally speaking, if it contains matter initiating its decomposition (organic amine, activated carbon, organic alkali), it is not necessary to add any initiators and reaction will go smoothly. If there is no such kind of matter in the system, organic alkali of 0.5-2% (weight of Triphosgene) DMF or pyridine will be added to another phase (usually two phases of reaction: one is Triphosgene solution, another is matter reacted with carbonyl chloride), controlling speed of one phase drip to another phase in order to reaction speed. Solution from Triphosgene include benzene, dichlorolurene, cyclohexane, chloroform, etc.. The solution for Triphosgene is not the matter of triggering its decomposition. The solution from another phase is that of triggering its decomposition.
