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.

Vast quantities of naphthalene potentially available in this country were not recovered because of the low prices prevailing until 1936. Since then an increase in the price of crude naphthalene from 1.55 cents to 2.5 cents and 3 cents per pound has stimulated production and has led to additional recovery.
