         2 . The thermoplastic resin according to  claim 1  which has a content of acetaldehyde represented by the following formula (2) of 200 ppm or less. 
       
         
           
           
               
               
           
         
       
     
     
         3 . The thermoplastic resin according to  claim 1  which has a content of fluoren-9-one represented by the following formula (3) of 200 ppm or less. 
       
         
           
           
               
               
           
         
       
     
     
         4 . The thermoplastic resin according to  claim 1  which is at least one selected from the group consisting of polycarbonate resin, polyester resin and polyester carbonate resin. 
     
     
         5 . The thermoplastic resin according to  claim 1 , wherein the b value of a pellet thereof is −10.0 to 10.0. 
     
     
         6 . The thermoplastic resin according to  claim 1  which is used in at least one selected from the group consisting of an optical film, optical disk, optical prism and optical lens. 
     
     
         7 . A process for producing a thermoplastic resin by reacting a dihydroxy component containing 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene with at least one component selected from the group consisting of a dicarboxylic acid component and a carbonic acid ester component, wherein
 the purity of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene is 99 wt % or more, and the content of phenoxyethanol is 1 to 500 ppm.   
     
     
         8 . The production process according to  claim 7 , wherein the content of fluoren-9-one represented by the following formula (3) in 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene is 500 ppm or less.
