Three, summary of the invention
The purpose of this utility model is for problem above, it is provided that a kind of stablize the attemperating unit of key node in controlled high-quality cationic etherifying agent production procedure.
The purpose of this utility model is achieved through the following technical solutions:
The attemperating unit of key node in a kind of high-quality cationic etherifying agent production procedure, it includes trimethylamine, hydrochloric acid, mixing dosing still, epoxychloropropane, synthesis reaction vessel, rear reactor, etherifying agent intermediate products tank, first cooling system, the second cooling system, first temperature elevation system and the second temperature elevation system, it is characterized in that mixing dosing still, synthesis reaction vessel, rear reactor and etherifying agent intermediate products tank arrange according to this, pipeline connection forms production line, trimethylamine is connected mixing dosing still by unified entrance respectively with hydrochloric acid, first cooling system accesses mixing dosing still, epoxychloropropane accesses the connecting pipeline between mixing dosing still and synthesis reaction vessel, the second cooling system and the first temperature elevation system are respectively connected to synthesis reaction vessel, reactor after second temperature elevation system access.
The attemperating unit of key node in high-quality cationic etherifying agent production procedure of the present utility model, compared with prior art, cationic etherifying agent production procedure is respectively provided with the most controlled cooling system of many sets and temperature elevation system on key node extremely sensitive to temperature.Make etherificate overall process all locate the optimum temperature environment of reaction, make reaction more fully and completely, be more convenient for and high-quality cationic etherifying agent can be produced, additionally there is following remarkable advantage:
1, to the mixing dosing of trimethylamine and hydrochloric acid in mixing dosing still, pre-cooling preparation is carried out by the first cooling system, remove natural excessive temperature and the heat energy of generation in both mixed processes of material, enter synthesis reaction vessel for dosing and lower the temperature rapidly, provide for the reserved adequate reaction time and ensure premise.
2, synthetic reaction is carried out in the range of synthesis reactor temperature being set and maintains 9-12 DEG C, than 15-18 DEG C commonly used in prior art, 12-15 DEG C of temperature-control range all closer to the lower limit critical point of reaction, the crystallization temperature making product is down to-8 DEG C by-4 DEG C, synthetic reaction process is not only made to produce impurity few, and improve product function activity, expand range of application, produce and more preferably apply effect.
3, the setting of the second temperature elevation system, makes the product in liquid ether agent insulation still more stable, for realizing reacting completely in rear reactor under higher temperature environment creating favorable conditions.Improve making full use of of etherifying agent raw materials for production, also reduce the impurity content of etherifying agent product, provide guarantee for producing high-quality resistance ion etherifying agent.
Four, accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the attemperating unit of key node in high-quality cationic etherifying agent production procedure.
Five, detailed description of the invention
The technical solution of the utility model is implemented in newly-built No. two lines of Dongying Guo Feng fine chemistry industry Co., Ltd of Dongying city:
As shown in Figure 1, the synthetic reaction flow process producing liquid cation etherifying agent CHPTAC (3-chloro-2-hydroxypropyl-trimethyl ammonium chloride) is respectively provided with on key node and stablizes controlled the first cooling system, the second cooling system, the first temperature elevation system and the second temperature elevation system device.
As a example by producing liquid cation etherifying agent technique, detailed description of the invention is as follows: by 1:1 molar ratio, dosing still is got in hydrochloric acid metering, trimethylamine vaporization is squeezed into continuously, mixing dosing still is got in hydrochloric acid metering, starts the first cooling system, hydrochloric acid cools to less than 30 DEG C, trimethylamine vaporization is squeezed into continuously, makes course of reaction temperature control between 20-60 DEG C；Trimethylamine hydrochloride transfers the epoxychloropropane of example 1.05:1 equivalent addition in molar ratio during synthesis reaction vessel, in synthesis reaction vessel, stirring starts the second cooling system while being mixed and carrying out synthetic reaction, making its course of reaction control temperature and maintains extremely reaction to be basically completed below 11 DEG C, before the liquid ether agent output that reaction generates, start the first temperature elevation system pre-heating temperature elevation to 12-15 DEG C, the primary liquid etherifying agent of reacted generation is after input after reactor, start the second temperature elevation system, liquid ether agent is heated, it is warming up to 30-35 DEG C and maintains 3 hours, continue to start the second temperature elevation system, it is warming up to 50-55 DEG C, add hydrochloric acid regulation pH value, material is turned to etherifying agent intermediate products tank after a period of time.
