Embodiment 1

[0056] 1).Suspension polymerization to generate product 1

[0057] The ratio is as follows (unit: gram)

[0058] Styrene 330 Divinylbenzene (content 55.4%) 70 Benzoyl peroxide 3 liquid wax 150 gelatin 5 Sodium chloride 10 pure water 1000

[0059] First add the water phase to a 2000ml reaction kettle, stir for 1 hour, raise the temperature to the reaction temperature, add the components of the oil phase, heat up to 95°C after setting, keep it warm for 10 hours, lower the temperature, wash with water, dry, extract wax, and dry to obtain product 1.

[0060] 2). Acylation reaction produces product 2

[0061] Swell 150 grams of product 1 in dichloroethane. After swelling for 2 hours, add sulfuryl chloride (molecular formula: S02Cl2) for acylation reaction. The molar ratio of white balls to sulfuryl chloride is 1:2, and the temperature is raised to 60°C , keep warm for 6h, cool down, wash with dichloroethane repeatedly for 3 times,...

Embodiment 2

[0069] Other steps are exactly the same as embodiment 1, only the amount of amine added in step 3 is different,

[0070] 3). Amination produces product 3

[0071] Swell 100 grams of product 2 with ethylene dichloride, add 10 grams of N,N'-dimethyl-1,6-hexanediamine, carry out amination reaction at 60°C, react for 40 hours, filter and wash , and dried to obtain the product 3.

[0072] Finally, a quaternary ammonium salt type strongly basic anion exchange resin, sample number A2 was obtained.

Embodiment 3

[0074] Other steps are exactly the same as embodiment 1, only the amount of amine added in step 3 is different,

[0075] 3). Amination produces product 3

[0076] Swell 100 grams of product 2 with ethylene dichloride, add 20 grams of N,N'-dimethyl-1,6-hexanediamine, carry out amination reaction at 60°C, react for 40 hours, filter and wash , and dried to obtain the product 3.

[0077] Finally, a quaternary ammonium salt type strongly basic anion exchange resin, sample number A3 was obtained.

Abstract

The invention discloses a manufacture method for high temperature resistance strong basicity anion exchange resin. Styrene / divinylbenzene crosslinked polymer micro-balls are used as the framework of the resin; acylation reaction is carried out between the styrene / divinylbenzene crosslinked polymer micro-balls and sulfuryl chloride (molecular formua: SO2CI2); -SO2CI function group is drawn into benzene ring of cinnamene; and then tertiary amine resin is synthesized by amination reaction between the styrene / divinylbenzene crosslinked polymer micro-balls and long carbochain diamine with N, N-dialkyl and further quaternized into Nalcite SAR. The thermal stability evaluation on quaternary ammonium resin shows that compared with the conventional Nalcite SAR, the thermal stability of the quaternary ammonium resin is obviously increased; the usage temperature can reach about 90-100 DEC C; the application field of the Nalcite SAR is expanded; thereby the high temperature resistance Nalcite SAR is obtained; the structural formula of the high temperature resistance Nalcite SAR is as follows: wherein, m equals to 1-12, n equals to 2m, P is styrene / divinylbenzene crosslinked polymer framework and R is alkyl.

Description

technical field [0001] The invention relates to a preparation process of an ion exchange resin, in particular to a preparation process of a high temperature resistant strong alkali anion exchange resin. technical background [0002] Strong base anion exchange resins can be used in water treatment, substance purification, concentration, separation, transformation of ionic composition of substances, decolorization of substances and catalysts, etc., but the use temperature of strong base anion exchange resins, especially hydroxyl resins, is limited to 60°C Below, this limits the scope of application of strong base anion exchange resins. [0003] There have been some announcements on the technology of developing high-temperature resistant strong basic anion exchange resins at home and abroad. In 1979, Soviet patent SU 675056 declared that 2% 2-mercaptobenzimidazole (antiaging agent B) was introduced into chloromethyl polystyrene resin. ), and then react with trimethylamine to p...
