trinitroresorcimol from picric acid
Today i´m going to make estyfnic acid from picric im not sure if what i´m going to do is corrrect but i´m going to try it anyway..
idea is to make de TNP react with sulfuric acid:
C6H4(NO2)3+H2SO4->H20+C6H4(OH)(NO2)3(HSO3) and then make it react with NaOH:
C6H4(OH)(NO2)3(HSO3) +2NaOH->Na2SO4+C6H4(OH)2(NO2)3
i´d like to put here the pictures of it but i dont know how....
well if you think that something is wrong let me know before i became an enormous hole in the ceiling.....

H2SO4 directs in meta of NO2 groups and in ortho and para of OH; thus there is no possible way to make it hold to the benzenic ring since all possible
positions are already taken by NO2 or OH!
You will simply end with:
NaHSO4, Na2SO4 and NaO-C6H2(NO2)3

Ethers orientate the same way as HO- (ortho and para)!
The bst you can do is to use sanger substitution:
metadichlorobenzene -HNO3/H2SO4-> TriNitroDiChloroBenzene
TNDCB = Cl2C6H(NO2)3
Cl2C6H(NO2)3 + NaOH (aq) --> (HO)2C6H(NO2)3 + 2 NaCl

I thought that dichlorobenzene was impossible to nitrate because of the highly deactivating afect of the halogens? So how would you nitrate it to
trinitrodichlorobenzene, let alone the mononitro compound?

HNO3 100% and H2SO4 96%! Cold the first half hour and then reflux boiling for 2 hours!
