| titleOfInvention | Method for extracting low boiling point component from high-polymer stock |
| abstract | PURPOSE: To make exact quantitative analysis of the low boiling point component contained in a high polymer stock by heating a liquid reservoir part to the temp. higher than the b.p. of a solvent (≤25°C) and lower than the b.p. of the low boiling point component and cooling a cooling part to ≤0°C. n CONSTITUTION: For example, a trichloromonofluoromethane CCl 3 F 23.8°C b.p.) is put as the solvent into the liquid reservoir part 11 and is heated by a heater 14 to 30W40°C. Then the CCl 3 F in the liquid reservoir part 11 evaporates and the vapor thereof is conducted to a side pipe 15 to the cooling part 13 where the vapor is cooled to about 0°C by ice 18 and is condensed. The condensate drops to an extraction part 12 and contacts with the high polymer stock, for example, silicone rubber and elutes a low molecular siloxane. The CCl 3 F is returned to the liquid reservoir part 11 when the height of the liquid level thereof exceeds the top end of a side pipe 16. The low molecular siloxane contained in the silicone rubber is migrated to the CCl 3 F in the liquid reservoir part 11 and is thereby extracted. Since the b.p. of the siloxane is higher by about 10°C than the b.p. of the CCl 3 F, the evaporation of the siloxane from the liquid reservoir part 11 hardly arises. The extraction at a high yield is, therefore, possible and the low boiling component contained in the high polymer stock is exactly quantitatively analyzed. n COPYRIGHT: (C)1987,JPO&Japio |
