  Triphosgene (CAS NO.32315-10-9) is prepared by exhaustive chlorination of dimethyl carbonate. The preparing process is the chlorination of methyl carbonate in the presence of fluorescence, ultraviolet ray and mixed medium and low temperature initiator in the amount of not more than 2 % of the material. The whole chlorination is completed in three stages at 15-50 deg.c, 50-70 deg.c and 70-90 deg.c separately. The said technological process obtains product of high purity and smelting point of 80-83 deg.c at a yield over 90 %.

  Triphosgene , with CAS number of 32315-10-9, can be called Bis(trichloromethyl)carbonate ; Bis(trichloromethyl) carbonate ; Methanol, trichloro-, carbonate(2:1) (9CI) ; Carbonicacid, bis(trichloromethyl) ester (6CI,8CI) . It is a white solid. Triphosgene (CAS NO.32315-10-9) is a chemical compound that is used as a safer substitute for phosgene, because at room temperature it is a solid crystal, as opposed to phosgene which is a gas, the crystals decompose at around 130 °C, although, the decomposition temperature of impure samples can be much lower. It is used in organic synthesis to bond one carbonyl group to two alcohols, as in the synthesis of octalactin B.
