Abstract: A number of substituted 1,8-naphthalimides and naphthalic anhydrides have been prepared and their absorption and fluorescence properties in absolute ethanol have been determined. In the absence of an alkylamino substituent in the naphthalene ring, the compounds are colourless and weakly fluorescent. In the presence of such a substituent they become yellow and frequently fluoresce strongly with quantum yields of the order of 0.8.

TL;DR: In the two-stage recovery of natural cashew nut-shell liquid by solvent extraction, the overall yields from half-shells obtained by mechanical cutting and from chilled fragmented shells (to solidify the phenols) by manual processing are identical, indicating that no physical loss of phenolic material occurs in the mechanical process as mentioned in this paper.

TL;DR: In this article, polyethoxylates from cardanol and from cardol, the main component phenolic lipids in technical cashew nutshell liquid derived from the replenishable source Anacardium occidentale, were obtained by reaction with ethylene oxide under base-catalyzed conditions.

TL;DR: In this article, the surface tension of aqueous solutions of cardanol and cardol polyethoxylates derived from technical cashew nut-shell liquid were examined to determine their relative surfactancy.

TL;DR: In this paper, the synthesis and characterisation of a series of novel 4-acylamino and 4-alkylamino-N-1,8-naphthalimides is described.
