ABSTRACT:
Dinitro alkyl phenols are produced free of tar when the precursor orthoalkylphenol is contacted with a molecular sieve prior to sulfonation, nitration, and air drying. The dinitro alkylphenols produced are free of tars or similar resins and avoid processing problems that are shown in impure prior art products.
