What reading level is Some New Condensations With Para Para Bis Dimethylamino Benzohydrol Michler book?
To quickly assess the difficulty of the text, read a short excerpt:
, 233. 5 fcorr. ).
A solution of 10 g. Of phthalimide (1 mole) and 18 g. ( 1 mole) of the hydrol, in 300 cc. Of alcohol, was boiled gently for 10 hours, and then cooled. Seventeen g. Of greenish- yellow leaflets separated from the cold solution, and 4 g. More was recovered by con- centrating the mother liquor, making the total yield 80%. The purified compound melted at 186. 7 (corr. ), and crystallized in greenish-yellow prisms or leaflets.
Analyses. Calc. For C^H^N, : C, 75. 18; H, 6. 27; N, 1...0. 52. Found: C, 74. 88, 75. 30; H, 6. 21, 6. 36; N, 10. 70, 10. 70.
The substance is soluble in cold acetone, difficultly soluble in ether or ligroin, and dissolves in alcohol, ethyl acetate, carbon disulfide, or benzene, at their boiling-points. As phthalimide is difficultly soluble in either carbon disulfide or benzene, it may be separated thus from its hydrol condensation product. When dry hydrogen chloride is passed into an anhydrous ether solution of the new compound, a greenish precipitate separates which is probably the mono-hydrochloride.
