摘要：

The dissolution behaviour of cellulose in low temperature molten salts was investigated. Depending on the chosen anions in the melt, cellulose shows different reaction behaviour in different Li+-containing melts. Dissolution of the polymer was observed in molten LiClO4. 3H(2)O and molten LiI . 2H(2)O. In the hydrated melts of LiCH3COO . 2H(2)O and LiNO3. 3H(2)O a fine distribution of cellulose was stated. Cellulose can be regenerated by cooling the melt and removing the salt by dissolution in water. The structure of the recrystallized product is determined by the used low temperature molten salt.
