With acetic acid; for 16h;Heating / reflux;Product distribution / selectivity; |
A three liter, four neck flask equipped with an overhead stirrer, a thermometer, a condenser, an argon inlet and outlet, was charged with: 104.10 grams of BPA-dianhydride (200mmol.) from the Ultem plant93 grams of 2-(4-Aminophenyl)-2-4'-Hydroxyphenyl)-propane (96%), and1000 ml of glacial acetic acid. The resulting mixture was refluxed for 16 hours under a flow of argon. By the time reflux started, all the reactants had passed into solution and no precipitation was observed throughout the reflux period. After 16 hours, the reaction was cooled to room temperature and quenched by pouring the reaction mixture into two 4L beakers each filled with water. A white precipitate formed. After stirring, the precipitate was isolated by filtration. The precipitate was then oven dried at 50C. The dried crystals were further purified by refluxing in 500 mL of ODCB for about 5 hours, subsequently re-precipitating by the crystals adding 100 mL of Xylene. The crystal composition was confirmed by 1H, 13C NMR. |

With triethylamine; In 1,2-dichloro-benzene; toluene; at 130℃; for 4.5h;Product distribution / selectivity; |
A 500 ml three-neck flask equipped with a mechanical stirrer and condenser was charged with 20 g (0.088 mol) of amino-BPA, 22.9 g (0.044 mol) of BPA dianhydride, 160 g of OBCB, 10.7 g of toluene, and 330 ppm triethyl amine. The flask was then purged with nitrogen and the reaction mixture heated to 130C and allowed to stir for 2 hours. An additional 10 ml of toluene was then added and the reaction allowed to continue for an additional 2.5 hours. The macromer was precipitated by adding 30 g of O-xylene while allowing the reaction mixture to cool. The macromonomer was filtered and dried at 50C for 10 hours. This product was soluble in tetrahydrofuran (THF), anisole, ODCB, dimethyl sulfoxide (DMSO), acetonitrile, and warm chlorobenzene. It was insoluble in diethyl ether, chloroform, and methylenechloride. An alternative "melt" route polymerization was as follows. A 100 ml three-neck flask equipped with a mechanical stirrer and condenser was charged with 11.45 g (0.050 mol) BPA dianhydride and 10.0 g (0.044 mol) amino-BPA. This mixture was then heated to 200C, and allowed to react for 1 hour under a nitrogen blanket. The product was then cooled and ground into a fine powder. |

With hydrogenchloride; aniline; In methanol; toluene; |
A. Preparation of 4-(1-(4-aminophenyl)-1-methylethyl) phenol A mixture of 134.0 grams (1.0 mole) of p-isopropenylphenol and 186.0 grams (2.0 moles) of aniline was stirred and heated to 150C. To the mixture was added 5.0 grams of a solution obtained by adding 1.28 grams of 10% hydrochloric acid to 93 grams of aniline and stirring the mixture well. The reaction was carried out for 3.0 hours at the 150C reaction temperature. The reaction product was cooled to 120C then 350 milliliters of toluene was added. The product was then cooled to 25C and the solid precipitated product was recovered by filtration. The crude product was slurried into 350 milliliters of methanol and heated to a reflux then maintained for 15 minutes. After cooling, the product was recovered by filtration and dried under vacuum to yield 4-(1-(4-aminophenyl)-1-methylethyl)phenol as a white powder. |
