14 H. E. Williams — Action of Neutral Salts on Cellulose 



P. von Weimarn in a German patent claims the action of 

 the aqueous solutions of all neutral salts on cellulose, such, 

 for example, as sodium sulphate, potassium chloride, and 

 also such sparingly soluble compounds as calcium sulphate 

 and calcium hydroxide ; he also mentions the thiocyanates 

 amongst the numerous examples he gives. 



Neither of these investigators mentions any specific con- 

 centration, or viscosity, or any limiting conditions for 

 obtaining the cellulose solution.
