Domestic producers of naphthalene are increasing their output, and they state that continued prices of 2.5 to 3 cents per pound for naphthalene solidifying at about 75° C. or slightly higher will stimulate production sufficiently to meet all present and near-future requirements. Estimates obtained in the summer of 1936 from the large tar distillers and a petroleum refiner indicate that production was appreciably greater in 1937 than in 1935. These estimates included the potential output of two new tar distillation plants under construction, the topping of large quantities of tar (hitherto used as fuel without removing any of the products), the recovery of appreciable quantities of naphthalene by several petroleum refiners, and increased output by other producers. Imports of crude naphthalene in 1937 amounted to 52,664,277 pounds valued at $1,133,157, or 2.2 cents per pound. World production. The output of naphthalene in the principal producing countries, in 1933 and 1935, is shown in table 35. Most of these statistics were estimated from the output of tar or of other distillation products given in official reports of the countries or in consular reports. The figures in table 35 indicate that the output in 1935 was an increase of about 100 million pounds over 1933 or 41 percent. Notwithstanding this sharp increase in world production, consumers had difficulty in obtaining their requirements. It is believed that the world output in 1937 substantially exceeded that in 1935.
