Sulfonation reaction kettle for sulfonated tobias acid

Abstract

The invention discloses a sulfonation reaction kettle for sulfonated tobias acid. The sulfonation reaction kettle comprises a kettle body; the kettle body is fixedly connected with a bracket; a feeding port and an acid liquor box are arranged on the upper side of the kettle body; a discharging valve is arranged on the lower side of the kettle body; a temperature regulator and a mother liquor headare arranged on the outer surface of the kettle body; a screw driven by a driving component is arranged in the kettle body; the screw is meshed with a sliding drum fixedly connected with a stirring blade; the screw is fixedly connected with a support pillar through a bearing; the support pillar is connected with the kettle body through a connecting plate; a temperature sensor is arranged on the lower part of the support pillar. The acid liquor box filled with acid liquor is arranged on the upper end of the reaction kettle, the acid liquor is added into the reaction kettle by an atomizing sprayer through a switch valve, and then the screw is driven to rotate by a motor and moves up and down together with the meshed sliding drum with the stirring blade, so that physicochemically treated acidliquor is in full contact with raw materials and the sulfonated tobias acid in ultrahigh purity can be prepared.

Description

technical field [0001] The invention relates to the technical field of chemical processing equipment, in particular to a sulfonated tunic acid sulfonation reaction kettle. Background technique [0002] Sulfonated Tuidelic acid can be used as an intermediate in the synthesis of reactive dyes, photosensitive materials and organic dyes. Reactive dyes, photosensitive materials and organic dyes are widely used in the textile industry, plate making industry, and dye industry, and the application fields are further expanding. Therefore, the demand for salt-free sulfonated turezic acid as an intermediate is also constantly increasing. Large, with broad market prospects and development space. [0003] The traditional processing steps of sulfonated tunic acid are: 1. acidification, 2. sulfonation, 3. acid analysis, 4. pressure filtration, 5. pulverization. In the process of processing, traditionally, the acid solution is directly added to the reaction kettle, and then stirred for pr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the acid solution is directly added to the reaction kettle in the traditional technology, and the acid solution cannot fully contact the raw materials, so that the processed sulfonated tunic acid has an impure composition. Proposed a sulfonated tunic acid sulfonation reactor
