Embodiment 1
[0110] Embodiment 1 has the preparation of the compound of structural formula 2 (c=0)
[0111] 51.06g (0.30mol) o-phenylphenol (abbreviated as OPP) and 0.41g zinc chloride are dropped into the 100ml there-necked flask equipped with constant pressure dropping funnel, Claisen tube, condenser tube, thermometer and magnetic stirring bar, Nitrogen. When the temperature in the system rises to 78°C and turns into a transparent liquid phase, start to add 45.33g of PCl dropwise 3 . During the dropwise addition, the reaction temperature was gradually increased to 165°C. PCl 3 After the dropwise addition was completed in 7.5 hours, the temperature was raised to 172° C. and kept warm until no HCl was generated. Then add 100g xylene to the system, and distill off excess PCl 3 . The crude product was obtained, and the product was denoted as DOPO-Cl. Take DOPO-Cl (33.41g, 142.5mmol) and 14ml of xylene into a three-necked flask equipped with a thermometer, a water separator, a magnetic...
Embodiment 2-15
[0112] Embodiment 2-15 has the preparation of the composition of structural formula 2 (c≠0)
[0113]The pure 6H-dibenzo[c,e[[1,2]oxaphosphorinane, 6,6'-(1,2-(1-phenyl)ethanediyl)bis -, 6,6'-dioxide and different organic compounds are mixed according to a certain ratio, and after stirring to make them fully mixed, the excess free solvent is evaporated at room temperature, and then dried in a vacuum oven at 150°C until the quality is constant . It was found that the obtained samples were all solid at 150°C, indicating that the melting point of these samples was higher than 150°C. Afterwards, the melting point of each sample was measured (referred to as melting point 1), and the content of organic compounds therein was determined by NMR (referred to as c1). After carrying out these tests, heat them to melting (the melting temperature is much higher than the boiling point of the organic compound), keep the heat for a certain period of time, until the organic compound is complete...
Embodiment 16
[0125] Preparation of embodiment 16 flame retardant polycarbonate
[0126] The American GE 141R PC polycarbonate plastic raw material (referred to as PC), Ciba antioxidant 1010 (the main chemical composition is tetrakis [3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid] quaternary Amyl alcohol ester), and the sample obtained from the above examples are mixed in plastic bags in advance according to the weight ratio of 94.75 / 0.25 / 5.0, and then extruded and granulated in a Brabender twin-screw extruder. The twin-screw extruder temperature was set at 270°C. Record whether the extrusion process is smooth or not, as shown in Table 2.
[0127] Table 2
[0128]
[0129] As can be seen from the table above, processing is smoother with the high melting point double DOPO (ie composition) containing the organic compound.
