  • Installation for the preparation of emulsion and suspensions

    Installation for the preparation of emulsions and suspensions refers to devices intended for the preparation of disperse systems. It can be used in the synthesis of polyhydric alcohols and other organic and organometallic compounds, where the immiscible liquids interact. The installation comprises a hydraulic jet mixer pump connected to the outlet of a hydromechanical dispersion pump. The installation comprises one or more components of the dispensing systems, each of which consists of a supply container and the dispenser. Technical result of the installation is created by intensifying the process of mixing and improving the quality of the final products.

  • Synthesis of sodium and potassium alkoxides using electrochemical methods

    The present work is devoted to development of methods for the synthesis of alkoxides of alkali metals. The main factors determining the rate of reaction of sodium with alcohols is a contact surface area solid and liquid phases and the power of the appropriate alcohol as acids. We studied the dependence of the rate of interaction of sodium metal with a variety of alcohols from their acid dissociation constant pKa. To slow the rates of interaction of sodium and potassium with alcohols were used their amalgams. Amalgam was obtained by electrolysis of sodium hydroxide and potassium hydroxide. The interaction process alkali metal amalgam flows quietly enough, even in the case of methyl alcohol and potassium amalgam. Technological scheme involves three stages: the electrolysis of sodium hydroxide at ordinary electrolytic with flowing mercury cathode; an anodic dissolution of the amalgam in an alcohol solution and recovering the sodium or potassium alkoxides. The proposed method allows the synthesis of sodium and potassium alkoxides in soft and controlled conditions.
