Chemistry – A European Journal, EarlyView.A new silver‐catalyzed H/D exchange reaction was developed for the labelling of quinones and related compounds. Both homogeneous and heterogeneous catalytic processes were implemented using heavy water as a simple deuterium source. The corresponding deuterated compounds were obtained with high isotopic enrichment through a practical method that opens ...

Fluorescence of Naphthoquinones [PDF]
Nature, 1954 ATTEMPTS to devise a method for the identification of vitamin K1 and other naphthoquinones by filter-paper chromatography led to the chance observation that some of these compounds exhibit a characteristic fluorescence which can be used for their detection. 10 µgm.

POLYPHENOLS AND NAPHTHOQUINONES EXTRACTION FROM WALNUTS PELLICULA: THE IMPACT ON KERNELS QUALITY [PDF]
Journal of Engineering Science (Chişinău), 2020 Walnuts change their appearance during storage, becoming brown and bitter. The aim of this paper was to determine the polyphenols and naphthoquinones extraction process parameters from the pellicle of kernels, and to assess the influence of extraction on

Decolorization of Disperse Dyes in Textile Polyester Recycling Using Activated Carbon
Chemie Ingenieur Technik, EarlyView.Decolorization of disperse dyes from disodium terephthalate solutions is examined using two activated carbons with varying pore structures and surface properties. The potential impact of pore size distribution and surface charge on the adsorption process is assessed to support optimized adsorbent selection.
