        Various potentialities are presented for obtaining from both gaseous and liquid hydrocarbons the intermediates for representative polyhydric alcohol-polycarboxylic acid resins.  The preparation of phthalic anhydride, intermediate for alkyd resins, from o-xylene secured by the aromatization of paraffinic naphthas is already relieving an acute shortage of naphthalene, formerly the principal charging stock for phthalic anhydride manufacture.  Possibilities are seen and discussed for synthesizing drying or semidrying oil fatty acids from a synthetic petroleum oil produced by the Fischer-Tropsch synthesis.
