Definitions

  • the present invention relates to the production Example 2 of artificial silk and similar artificial products In a Similar manner and with the same including ribbons films r especially m zle a. similar solution ofv cellulose triacetate was cellulose esters of carboxyhc acids, and one of its precipitated in toluene objects is the production of products of this kind,
  • Example 1 Dames A fibriform cellulose triacetate washed and 3;, ⁇ g5 50 dried in the usual manner was dissolved in a fig mixture formed of 95 parts by volume methylene '15 chloride and 5 parts alcohol, the concentration -10 1111 2.45 13 1.92 of the solution used in the difierent tests being shown in the following schedule in cubic centi- Example 4 .15 of the solvent j fi of the i k The A cellulose diacetate dissolved in the same solu long 9 m e manner We f vent mixture was precipitated in ether.
  • cellulose esters mentioned above also other simple cellulose esters, such as the formates, propionates or butyrates or mixed cellulose esters, such as the acetoformates, acetopropionates or acetobutyrates, as well as the products obtained by subjecting the primary esters to a more or less far reaching hydrolytic decomposition may be subjected to the new process, the most suitable solvents being used in each individual case.
  • the precipitating liquors can be used much longer without being regenerated, than can be done in a process operating at higher temperature, because the precipitating efiect is preserved at the low temperatures even if the liquor is highly diluted by the solvents.
