Production device and production method of liquid sodium dimethyl dithiocarbamate

Abstract

The invention discloses a production device and a production method of liquid sodium dimethyl dithiocarbamate. The production device comprises a reaction kettle, wherein the upper part of the reaction kettle is respectively communicated with a dimethylamine head tank, a sulfur dioxide head tank and a sodium hydroxide head tank by pipelines; the lower part of the reaction kettle is connected with a reaction kettle dump valve; and the reaction kettle dump valve is sequentially communicated with a filter, a finished product allocation tank and a finished product storage tank sequentially by pipelines. The production method comprises the following steps of: measuring carbon bisulfide, a 30% sodium hydroxide solution and 40% dimethylamine at a mass ratio, placing a dimethylamine solution into the reaction kettle, mixing, supplying a cooling medium to a reaction kettle jacket and an internal cooling coil tube, pressing carbon bisulfide into a synthetic kettle when the temperature of the kettle drops to 10-20 DEG C, then pressing the 30% sodium hydroxide solution into the synthetic kettle, slowly opening a synthetic kettle dump valve, and pressing a material in the reaction kettle into the filter and then into the finished product allocation tank.

Description

technical field

[0001] The invention relates to a production device and a synthesis method of liquid formex sodium, belonging to the technical field of chemical products. Background technique

[0002] Forma sodium (scientific name sodium dimethyl dithiocarbamate) is one of the important dialkyl dithiocarbamate. In the rubber industry, it is used as a terminator for emulsion polystyrene butadiene rubber and styrene butadiene latex, as a vulcanization accelerator for rubber products, as a bactericidal algae and slime preventive agent in industrial water treatment, and as a bactericide in petroleum and paper industries. Algaecide, used in agriculture to produce insecticides such as thiram, thiram, etc., used in mining as a beneficiation agent for manganese ore, copper ore, gold and silver ore, etc., and also used as a wood preservative. It is a large amount used at home and abroad. Dialkyl dithiocarbamate species.
