摘要:
A process for producing an organic trisulfide compound comprises contacting, in the presence of a catalyst, a mercaptan with an organic polysulfide compound to produce a product mixture and optionally contacting the product mixture with an acid wherein the catalyst comprises a base and optionally a surfactant and the organic polysulfide contains about 4 or more sulfur atoms per molecule.
摘要:
A composition, useful for dissolving sulfur, which comprises a major amount of a disulfide or polysulfide and a catalyst comprising one or more polyalkyleneoxyamines or polyamines, and methods for using the composition in a system to prevent sulfur-plugging, are disclosed.
摘要:
A process for preparing a fluorine-substituted alicyclic diol comprising hydrogenating in the presence of a catalyst a fluorine-substituted aromatic diol represented by formula (I): wherein Ph represents a divalent organic group containing at least one aromatic group, to obtain the fluorine-substituted alicyclic diol represented by formula (II): wherein Ph(H) represents a divalent organic group containing at least one perhydroaromatic group.
