specific Embodiment approach

[0013] The specific implementation method is as follows, trimethylamine and epichlorohydrin with a molar ratio of 1:4 are combined in a synthesis reactor after weighing to form a primary solid cationic etherifying agent;

[0014] Feeding: Before injecting the primary solid cationic etherification agent, adjust the rotating gear 6 to make the reactor 1 in a vertical state through the rotating bearing 5 and the rotating shaft 4, and check whether the equipment is normal. Turn on the vacuum pump 16, adjust the three-phase rotary joint 11, through the air inlet 17 and the air outlet 18, vacuumize for 15 minutes, the negative pressure is greater than 0.07 MPa, open the feed inlet 19, put the primary solid cationic etherification agent into the filter screen 7 above;

[0015] Pressure filtration: connect the dry nitrogen pipe at the nitrogen inlet 14, adjust the three-phase rotary joint 11, and blow in nitrogen through the nitrogen inlet 14, and when the pressure in the reactor 1 is...

Abstract

The invention discloses an integrated reaction kettle for uniform pressure filtration, washing and drying of a solid cationic etherifying agent. Through pressure filtration, washing and drying integrated arrangement, the integrated reaction kettle solves the problems that at present, the production process of the solid cationic etherifying agent is cumbersome, the human labor intensity is high, and the granular solid cationic etherifying agent is molten once being attached to a wall; the integrated reaction kettle is simple in operation, reduces the labor cost, improves the production efficiency, and can produce a uniform granular high-purity and high-quality solid cationic etherification agent.

Description

technical field [0001] The invention is designed for fine chemical industry, specifically a solid cationic etherification agent, which integrates pressure filtration, washing and drying into one reaction kettle. Background technique [0002] Solid cationic etherifying agent (EPTAC for short) is a multifunctional fine chemical product, which can react with various substances such as starch, cellulose, guar gum, polyacrylamide, etc. to produce a variety of products, and is widely used in the paper industry, Daily chemical industry, petroleum industry and water treatment industry and other fields. In its production process, in order to obtain a uniform granular, high-purity solid cationic etherification agent, it needs to be filtered, washed and dried. At present, it is treated separately, which is cumbersome, labor-intensive, and inefficient; and the applied filter press adopts a jacket combination, which easily melts the iron wall of the granular solid cationic etherificatio...
