Source: Compiled from official statistics of the United States Department of Commerce. United States exports. Exports are not shown separately; it is doubtful if any naphthalene is exported. Demand in the United States has exceeded domestic production. Competitive conditions. The commercial development and widespread application of surface coatings and finishes made from alkyd resins, in which phthalic anhydride and glycerin are the principal components, has resulted in a world-wide shortage of naphthalene, which is a raw material used in making phthalic anhydride. In recent years about one-half of domestic requirements of crude naphthalene have been imported (see table 46) from Europe, principally Germany and the United Kingdom. Increased demand for the same purposes, in these countries, has so reduced the quantities available for export as to create a serious shortage in the United States. Germany placed an embargo on exports late in 1935 and continued it until late in 1937.
