Organic anthracene carboxylate

Many organic compounds react with carboxylic acids, acyl halides, or anhydrides in the presence of certain metallic halides, metallic oxides, iodine, or inorganic acids to form carbonyl compounds. The reaction is generally applicable to aromatic hydrocarbons. Benzene, alkylbenzenes, biphenyl, fluorene, naphthalene, anthracene, acenaphthene, phenanthrene, higher aromatic ring systems, and many derivatives undergo the reaction. 

Silver oxide, easily prepared from silver nitrate and sodium hydroxide, is probably the best reagent for the preparation of pure acids from aldehydes. An additional advantage is that it does not attack other easily oxidizable groups in the molecule. Typical examples are 3-thiophene-carboxylic acid (97%), palmitic acid (98%), and anthracene-9 carboxyIic acid (72%). Its use in the preparation ol olefinic acids from olefinic aldehydes is illustrated by the preparation of 2-methyI-2-pentenoic acid (60%). Organic peracids have also been used in the oxidation of aldehydes to carboxylic acids. ... 

PO can be made degradable by means of additives. The types of additives include aromatic ketones (benzo-phenone and substituted benzophenones [47], qui-none), aromatic amines (trisphenylamine), polycyclic aromatic hydrocarbons (anthracene, certain dyes such as xanthene dyes), or transition metal organic compounds. The transition metal compounds of Fe, Co, Ni, Cr, Mn are widely used. Organo-soluble acetyl acetonates of many transition metals are photooxidants and transition metal carboxylates are also thermal pro-oxidants. Co acetylacetonate appears to be an effective catalyst for chemical degradation of PP in the marine environment. The preferred photoactivator system is ferric dibutyldithiocarbamate with a concentration range of 0.01. 1%. Scott has patented the use of organometallic compounds hke iron (ferric) dibutyldithiocarbamate or Ni-dibutyl-dithiocarbamate [48]. Cerium carboxylate [49] and carbon black are also used in such materials [50].
