Which solvent is used for reaction with soda cellulose in the production of regenerated cellulose?

Which solvent is used for reaction with soda cellulose in the production of regenerated cellulose? Correct Answer carbon disulphide

Soda cellulose is transformed into sodium cellulose xanthate by reacting it with CS2 i.e. carbon disulphide. The xanthate formed is soluble in dilute aqueous alkali, which on acidification decomposes; the xanthate structure is broken and cellulose is regenerated.

The given bar graph represents data of the production of paper (in ten lakh tonnes) by three different companies X, Y and Z during the years 2008 to 2012. The x-axis shows the 'years' and the y-axis represents the 'production of paper (ten lakh tonnes)'. (Note: The data shown is only for mathematical exercise. They do not represent actual figures.)  The total production of Company Y during 2008 and 2009 and Company X for 2011 and 2012 taken together is p% (p is correct to the nearest integer) more than the total production of Company Z during 2010, 2011 and 2012. The total production of Company Z during 2008 and 2009 taken together is q% (q is correct to the nearest integer) less than the total production of Company X during 2008, 2009 and 2012 and Company Y during 2010 and 2011 all together.  What is the positive difference between p and q ?
