A side stream hydrocarbon product of narrow boiling range that, after passing through the stripper, may be suitable for the aliphatic solvent Varsol. 3. An overhead hydrocarbon product that is sent the secondary (vacuum) tower where the overhead product from the primary tower is divided into an...
Naphthamides - substituent chemical shifts - reverse substituent effect - π-polarisationSubstituent induced 13 C NMR chemical shifts of side chain carbonyl carbons of several 4-substituted 1-naphthamides have been measured in DMSO- d 6 solvent. Analysis of the substituent induced chemical shifts by...
The naphthoquinones of this invention may also be formulated as topical ointments. A "classical" ointment is a semisolid anhydrous composition which may contain mineral oil, white petrolatum, a suitable solvent such as a glycol and may include propylene carbonate and other pharmaceutically suitable add...
