Abstract

The invention relates to an introduction device for chlorine measurement, belonging to accurate measuring addition device. It is characterized in that it comprises chlorine bottle, continous measuring scale for chlorine bottle, chloride outlet valve, chlorine pipe, chlorine measuring device, chlorine adjusting valve and chlorine distributorp; chlorine bottle is set on said continous measuring device, one end of chlorine pipe is connected with chlorine bottle and connected with chlorine outlet valve, chlorine measuring instrument, chlorine adjusting valve in sequence; the other end is equipped with chlorine distributor that inserts into chlorination reaction kettle. The device enables chlorine to be fed into chlorination reaction kettle continuously, safely and quantitatively, makes the chlorination easy to realize and chlorine content in resin can be controlled accurately. The device can be widely used in phenylethylene high temperature-resistance resin chlorination process.

Description

technical field [0001] The invention belongs to a device for accurately metering and adding gaseous chlorine in a chlorination process, in particular to a chlorine gas metering and introducing device in a chlorination process for a styrene-based high-temperature-resistant resin. Background technique [0002] Styrene-divinylbenzene polymer white balls are widely used in organic synthesis industries such as etherification, hydration, esterification, and alkylation as high-temperature-resistant strong acid cationic resin catalysts. It has the advantages of low corrosion to equipment and high product purity. . At present, the method to improve the high temperature resistance of the resin is mainly to introduce electron-withdrawing groups such as halogens (F, Cl, Br) on the aromatic ring. In the industrial production process, the temperature resistance of the resin catalyst is not only determined by the halogenation temperature, but more importantly, the speed and amount of halo...
