Abstract

The invention discloses a production device of potassium dimethyldithiocarbamate and a preparation method thereof. The production device comprises a reaction kettle, wherein a dimethylamine overhead tank, a sulfur dioxide overhead tank, a potassium hydroxide overhead tank and a soft water overhead tank are respectively communicated to the upper part of the reaction kettle through pipelines; and a filter and an end product storage tank are sequentially and respectively communicated with a reaction kettle discharging valve through pipelines. The production method comprises the steps of: respectively metering carbon disulfide, concentration potassium hydroxide solution with the concentration of 40%, concentration dimethylamine solution with the concentration of 50% and softened water in proportion by mass, firstly putting the concentration dimethylamine solution with the concentration of 50% into the reaction kettle, starting stirring, and introducing cooling media into a reaction kettle jacket and an inner cooling coil by utilizing a cooler; when the kettle temperature decreases to 5-20 DEG C, respectively adding the carbon disulfide and concentration potassium hydroxide solution with the concentration of 40% into the reaction kettle, then adding the softened water, after reacting for 100-150min, slowly opening the reaction kettle discharging valve, and sequentially pressing materials in the reaction kettle into a filter and the end product storage tank.

Description

technical field [0001] The invention relates to a production device and a production method of liquid thiram potassium, belonging to the technical field of chemical product production. Background technique [0002] Potassium thiocarbamate (scientific name potassium dimethyl dithiocarbamate) is a light green liquid with an irritating ammonia odor. Its main uses are: industrial wastewater treatment; heavy metal sinking tablets; paper industry; chemical industry, daily chemical industry, coating and Disinfectant and bactericide in other industries; polymerization inhibitor for some polymer synthesis; rubber vulcanization accelerator, styrene-butadiene rubber polymerization terminator, etc. [0003] In industrial water treatment, the excessive reproduction of bacteria and algae will reduce the heat transfer efficiency, and accelerate the corrosion and perforation of equipment. Excessive bacteria and algae in oilfield water will produce a large amount of slime to block equipment...
