Related Products of 1806-29-7, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.1806-29-7, Name is 2,2-Biphenol, molecular formula is C12H10O2. In a patent, introducing its new discovery.

The invention discloses a synthesizing method and a synthesizing device of phosphonitrilic chloride trimer as well as a preparation method of terphenyl cycloposphazene. The synthesizing method of the phosphonitrilic chloride trimer comprises the following steps: A1, adding powdered ammonium chloride and phosphorus pentachloride into a ceramic reaction kettle in a weight ratio of (900-1500):3000; A2, adding zinc chloride, heating and stirring to react, constantly dripping an acid-binding agent during stirring, wherein the weight ratio of zinc chloride to phosphorus pentachloride is (20-35):3000, the weight ratio of the acid-binding agent to the phosphorus pentachloride is (30-50):3000, the reacting temperature is 65-150 DEG C, and the reacting time is 1.5-2.5 hours; and A3, feeding to sublimation purifying equipment by adopting a closed screw rod, heating to 125-135 DEG C, and sublimating to obtain the phosphonitrilic chloride trimer.
