2 Phenyl 2-hydroxyethane 1 sulfonate

N 18-58%, OB to C02 -70.8%. Pale yel crysts, mp 213-218°. Will(Ref 2) claimed that he prepd the compd with mp 212° either by nitration of dinitro-bibenzyl or by oxidation of a-TNT, but he gave no detailed procedures. Rinkenbach Aaronson(Ref 3) obtained it in a very small quantity [together with a large amt of 2,4,2 ,4 ,6 -pentanitro-a-hydrox-ybibenzil, (02N)3CeH,.CH2.CH(0H).C6H3(N02), also called a-2,4,6-trinitrophenyl-jS-2,4-dinitro-phenyl-hydroxyethane] when they nitrated the previously sulfonated tetranitrobibenzyl by a rather complicated procedure. Mecir(Ref 3a) claimed to have prepd the hexanitro-compd by treating a-TNT with an aq soln of Na sulfite... 

Further crops may be taken, but the recovery of pure material from them is not worth the time required. They consist mainly of sodium 2-phenyl-2-hydroxyethane-l-sulfonate along with some sodium sulfate.
