Xanthate salts of alkali metals are produced by the treatment of an alcohol, alkali, and carbon disulfide.The process is called xanthation. [2] In chemical terminology, the alkali reacts with the alcohol to produce an alkoxide, which is the nucleophile that adds to the electrophilic carbon atom in CS 2. [3]
The intermediate is a xanthate. It is named for its discoverer, the Russian chemist Lev Aleksandrovich Chugaev (1873–1922), who first reported the reaction sequence in 1899. In the first step, a xanthate salt is formed out of the alkoxide and carbon disulfide (CS 2). With the addition of iodomethane, the alkoxide is transformed into a methyl ...
Process tracing methods in psychology are defined as observations which are made before the participant has come to a decision. These observations are used to present us with information regarding the psychological processes occurring within a participant, while they are weighing their choices. [ 1 ]
Background Chlorine and caustic soda are produced at chlor-alkali plants using mercury cells or the increasingly popular membrane technology that is mercury free and more energy-
Sodium ethyl xanthate (SEX) [3] is an organosulfur compound with the chemical formula CH 3 CH 2 OCS 2 Na. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. [4] A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt.
In terms of mechanism, an ideal RAFT polymerization has several features. The pre-equilibrium and re-initiation steps are completed very early in the polymerization meaning that the major product of the reaction (the RAFT polymer chains, RAFT-P n), all start growing at approximately the same time. The forward and reverse reactions of the main ...
Potassium amyl xanthate (/pəˈtæsiəm ˌæmɪl ˈzænθeɪt/) is an organosulfur compound with the chemical formula CH 3 (CH 2) 4 OCS 2 K. It is a pale yellow powder with a pungent odor that is soluble in water. It is widely used in the mining industry for the separation of ores using the flotation process.
Metapsychology (Greek: meta 'beyond, transcending', and ψυχολογία 'psychology') [2] is that aspect of a psychological theory that discusses the terms that are essential to it, but leaves aside or transcends the phenomena that the theory deals with.
