A Novel Stereospecific Synthesis of Glycosyl Cyanides from 1,2-O-Sulfinyl Derivatives
, 2016 An efficient synthesis of 1,2-trans-glycosyl cyanides via 1,2-O-sulfinyl monosaccharides is described. Such SN2-type displacements at the anomeric center are stereospecific and are best performed with sodium cyanide in the presence of ytterbium triflate.

Removal of Cyanide in Gold Cyanide Residues through Persulfate-Advanced Oxidation Process
Minerals, 2023 The toxic cyanides in gold cyanide residues produced in the cyanidation process of gold extraction threaten environmental safety and inhibit the recovery of valuable metals. In this study, the removal of cyanide through the persulfate-advanced oxidation process was investigated, and heat activation and ultrasonic activation were tested for cyanide ...

The cyanide sensitivity of the residual respiration inSchizosaccharomyces japonicus [PDF]
FEMS Microbiology Letters, 1984 Abstract Schizosaccharomyces japonicus, a highly respiratory deficient yeast species, contains two terminal oxidase systems. One is highly sensitive to cyanide like the main terminal oxidase system of respiratory sufficient yeasts. The alternative system is hardly sensitive to cyanide like the usual terminal oxidase system of other respiratory ...

Fermentation, 2023 Cyanide is a strong toxin in many tropical forage plants that can negatively affect ruminants. The aim of this study is to determine the cyanide removal efficiency, silage quality, and in vitro rumen fermentation of fresh cassava roots ensiled without an additive (control) and with Acremonium cellulase (AC), two cyanide-utilizing bacterial inoculants ...

Test of Comprehensive Recovery of Cyanide Residue
Kuangchan zonghe liyong, 2023 This is an essay in the field of mineral processing engineering. Cyanide tailings of a gold mine contain gold 0.45 g/t, and the gold mainly exists in the form of vulcanized gold and is mainly distributed in coarse particles. After the classification treatment, for the +0.037 mm ore sample, under the condition of grinding fineness -0.037 mm content of ...

Experimental Study on Removing Cyanide and Fixing Arsenic from Cyanide Residue of a Gold Mine
Kuangchan zonghe liyong, 2022 The total cyanide and arsenic in a cyanide residue of a gold mine exceed the standard requirements. The process of hydrogen peroxide oxidation decomposition cyanide and ferrous sulfate complexation fixation arsenic is studied. The results showed that in the cyanogen removal section, the amount of hydrogen peroxide added was 2 ml/L, the reaction time ...
