Usage

General Description

Bianthronyl is a synthetic organic compound that belongs to the family of polycyclic aromatic hydrocarbons. It is a highly stable and non-reactive chemical with a molecular formula of C28H14. Bianthronyl is widely used in the production of dyes, pigments, and optical brighteners. Its unique chemical structure and properties make it a valuable component in a variety of industrial applications, including inks, textiles, and plastics. However, due to its potential to be harmful to human health and the environment, strict regulations and guidelines are in place for the handling and disposal of bianthronyl-containing products.

Electrolysis at an Anthracene Crystal/Aqueous NO3- Solution Interface: The Role of Crystal Defects

The electrolysis of a 1 M solution of NaNO3 by means of an anthracene crystal electrode results in the production of many surface reaction products, including 9-nitroanthracene (9NA), bianthronyl (BA), and anthraquinone (AQ).The production of 9NA and BA have been shown to depend on the square of the current density.This dependence was rationalized by hypothesizing the need for the simultaneous discharge of two carriers at adjoining lattice defect sites.By annealing the crystals, it was found that the efficiency of producing 9NA was reduced by a factor of as much as 6; this supports the hypothesis.

Direct Exploitation of the Ethynyl Moiety in Calcium Carbide Through Sealed Ball Milling

Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC2 with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing α-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.
