What reading level is Researches On Modern Brisant Nitro Explosives book?
To quickly assess the difficulty of the text, read a short excerpt:
There is thus obtained a white solid which melts in a sluggish manner between 240 and 265; its recrystallization is attended with great loss (50%); it is best to use nitric acid, sp. Gr. 1. 49, at first, and then glacial acetic acid. Melting point, 278, cor. (after 200, 10 per minute). However, the purest product begins to soften about 265 . 1 When the filtrate from the recrystallization in nitric acid, sp. Gr. 1. 49, is poured into water, a precipitate is obtained which melts in a sluggish man...ner between 215 and 250; this was at first believed to consist of the 2, 4, 6, 3', 4 /, 6 / -hexanitrodiphenylether, contaminated with 2, 4, 6, 3', 4 / -pentanitrodiphenylether. But if this product is nitrated as directed above, that is to say with nitric acid of 1. 49 sp. Gr. And 30% oleum during four hours at 90, the melting point does not vary appreciably. This mixture is then probably composed of 2, 4, 6, 3', 4 /, 6 / -and 2, 4, 6, 2', 3', 4'-hexanitrodiphenylether. 2 A de- termination of nitrogen shows that this mass is composed almost entirely of hexanitro derivatives.
