Abstract

The invention discloses a continuous production technique for ethoxyl ethylene diamine, which comprises the following steps: the raw material ethylene diamine is thrown into a high order metering tank so that the ethylene diamine naturally flows into an ethylene diamine heater through level difference, the ethylene diamine is heated to 100-120 DEG C, and the ethylene diamine enters a reactor after controlling the flow rate to 1000-1600 L / H by a flowmeter; the raw material oxirane enters the reactor after controlling the flow rate to 10-30 L / H by an oxirane storage tank; and the raw materials react in the reactor to generate the reactant liquor. The invention also discloses a reactor for continuous production of ethoxyl ethylene diamine. The technique realizes continuous production of ethoxyl ethylene diamine, has the advantages of simple and convenient production technique, and easy operation, and ensures production safety and stable product quality.

Description

technical field [0001] The invention relates to a production process for continuous production of hydroxyethylethylenediamine and a reaction device for continuous production of hydroxyethylethylenediamine. Background technique [0002] The kettle reactor is a reactor widely used in production. It can be used for homogeneous reactions, and can also be used for heterogeneous reactions dominated by liquid phases. The structure of the tank reactor is mainly composed of four parts: the shell, the stirring device, the shaft seal and the heat exchange device. The shell structure of the kettle reactor includes a cylinder, a bottom, a cover (or a head), a hand hole or a manhole, a sight glass and various process nozzles, etc. The kettle-type reactor in the prior art is mainly used in the instant reaction process of the gas and liquid two phases in the chemical reaction engineering, realizes the full contact of the gas and the liquid two phases and generates a reaction product in a ...
