Abstract

8684. Cosway, H. C., and United Alkali Co. April 12. Nitrohydrocarbons which are liquid at ordinary temperature, are prepared by nitrating the coal-tar hydrocarbons referred to in Specification 13,861/11 with a mixture of nitric and sulphuric acids. The limits of concentration and composition are an acid of specific gravity 1-7, containing approximately 1 part of nitric acid, 2 parts of sulphuric acid, and 2¢ parts of water, and an acid of specific gravity 1-5, containing approximately 1 part of nitric acid, 2 parts of sulphuric acid, and 1-4 parts of water.
