Bis(2,6-diisopropylphenyl)carbodiimide Use and Manufacturing
To a stirring solution of DippN(H)C(S)N(H)Dipp (7.93g, 20.0mmol) and NEt110 g of Stabaxol 1 was mixed with 50.5 g of hexamethylene diisocyanate trimer (HDI trimer). The mixture was placed in a dried sample container, then sealed and heated to 110 C. under continuous stirring for 7 hours. After the reaction was completed, the mixture was cooled to room temperature to produce Precursor 10 with a yield of about 98%. Precursor 10 was characterized by FT-IR spectroscopy and the result is shown in FIG. 10. According to FIG. 10, Precursor 10 has a characteristic absorption peak (C'O or C'N) at 1716 cm-1, and the absorption peaks observed at 2270 cm-1 and 2154 cm-1 are assigned to remaining unreacted isocyanate and carbodiimide residue respectively.73.2 g of Stabaxol 1 was mixed with 22.3 g of isophorone diisocyanate (IPDI). The mixture was placed in a dried sample container, then sealed and heated to 110 C. under continuous stirring for 7 hours. After the reaction was completed, the mixture was cooled to room temperature to produce Precursor 9 having the following structure with a yield of about 98%. Precursor 9 was characterized by FT-IR spectroscopy and the result is shown in FIG. 9. According to FIG. 9, Precursor 9 has a characteristic absorption peak (C'O or C'N) at 1720 cm-1, and the absorption peaks observed at 2270 cm-1 and 2154 cm-1 are assigned to remaining unreacted isocyanate and carbodiimide residue respectively.73.2 g of Stabaxol 1 was mixed with 26.5 g of 4, 4?-dicyclohexylmethane diisocyanate (H12MDI). The mixture was placed in a dried sample container, then sealed and heated to 110 C. under continuous stirring for 7 hours. After the reaction was completed, the mixture was cooled to room temperature to produce Precursor 8 having the following structure with a yield of about 96%. Precursor 8 was characterized by FT-IR spectroscopy and the result is shown in FIG. 8. According to FIG. 8, Precursor 8 has a characteristic absorption peak at 1715 cm-1, and the absorption peaks observed at 2270 cm-1 and 2154 cm-1 are assigned to remaining unreacted isocyanate and carbodiimide residue respectively.73.2 g of Stabaxol 1 was mixed with 25.6 g of methylene diphenyl diisocyanate (MDI). The mixture was placed in a dried sample container, then sealed and heated to 110 C. under continuous stirring for 7 hours. After the reaction was completed, the mixture was cooled to room temperature to produce Precursor 6 having the following structure with a yield of about 99%. Precursor 6 was characterized by FT-IR spectroscopy and the result is shown in FIG. 6. According to FIG. 6, Precursor 6 has a characteristic absorption peak (C'O or C'N) at 1720 cm-1, and the absorption peaks observed at 2270 cm-1 and 2154 cm-1 are assigned to remaining unreacted isocyanate and carbodiimide residue respectively.73.2 g of Stabaxol 1 was mixed with 16.8 g of HDI. The mixture was added into a 500 mL three-neck flask, and toluene was then added thereto under dry nitrogen. The reaction system was heated to 110 C. under continuous stirring for 22 hours. After the reaction was completed, the mixture was cooled to room temperature. Finally, toluene was distilled out under reduced pressure to produce Precursor 4 having the following structure with a yield of about 99%. Precursor 4 was characterized by FT-IR spectroscopy and the result is shown in FIG. 4. According to FIG. 4, Precursor 4 has a characteristic absorption peak (C'O or C'N) at 1728 cm-1, and the absorption peaks observed at 2268 cm-1 and 2154 cm-1 are assigned to remaining unreacted isocyanate and carbodiimide residue respectively
