Method for preparing thionocarbamates and co-producing 2-mercaptoethanol or O-alkylthioethyl xanthogenate

The invention belongs to field of mineral flotation collecting agent materials and in particular discloses a method for preparing thionocarbamates. The method comprises the following steps: carrying out esterification reaction on xanthogenate and 2-halogenated ethanol to obtain O-alkyl-S-hydroxyethyl xanthogenate; carrying out ammonolysis reaction on the O-alkyl-S-hydroxyethyl xanthogenate and fatty amine to obtain a mixture of the thionocarbamates and 2-mercaptoethanol; after carrying out alkali washing on the mixture of the thionocarbamates and the 2-mercaptoethanol, carrying out oil-water separation, wherein an oil phase is the thionocarbamates and a water phase is 2-hydroxyethanethiol salt; carrying out acid washing on the 2-hydroxyethanethiol salt to obtain 2-mercaptoethanol. The invention further provides O-alkylthioethyl xanthogenate which is prepared by enabling the 2-hydroxyethanethiol salt and alkyl halide to react to obtain 2-alkylthioethyl ethanol and enabling the 2-alkylthioethyl ethanol to react with carbon disulfide and alkali. According to the method provided by the invention, the yield of the prepared thionocarbamates, 2-mercaptoethanol and O-alkylthioethyl xanthogenate is high and the purity is high; a product is easy to separate and purity and co-production is realized; the cost is saved and the reaction efficiency is also improved; the method is green and environmentally friendly.

Method for preparing thionocarbamate and trithiocarbonate

The invention discloses a method for preparing thionocarbamate and trithiocarbonate. The method comprises the following steps: carrying out an esterification reaction on alkyl xanthate salt and a halogenation reagent to obtain alkyl xanthate ester; carrying out an aminolysis reaction on the alkyl xanthate ester and fatty amine to obtain a thionocarbamate and mercaptan compound mixture; and carrying out an addition reaction on the thionocarbamate and mercaptan compound mixture and carbon disulfide in the presence of caustic alkali, and carrying out solid-liquid separation to obtain a liquid phase which is the thionocarbamate product and a solid phase which is the trithiocarbonate product. The products prepared through the preparation method have high yield and high purity, and the method allows the two high-efficiency collectors comprising thionocarbamate and trithiocarbonate to be simultaneously produced, and has the advantages of easiness in separation of the products, high atom economy property, low production cost, and easiness in realization of industrial production.
