Abstract

109,836. Heyl, G. E. Sept. 25, 1916. Tar oils, purifying.-Naphthalene is removed from coal-tar oils and other hydrocarbons by treating them first with dilute caustid alkali solution, and cooling to separate the bulk of the naphthalene; and then with solid or concentrated caustic alkali, sufficient to neutralize the tar acids remaining in the oil, either before or during distillation. The treatment before distillation may be carried out at ordinary or raised temperature, and the naphthalene separates on cooling or standing. A small quantity of concentrated alkali is added to the oil during distillation to cause retention in the still of darkcoloured substances. In the treatment during distillation, the naphthalene separates in the condenser.
