Daim ntawv thov:

Chloropontic anhydride thiab chloropontic acid yog reactive nplaim retardants haum rau unsaturated polyesters, polyurethanes thiab epoxies, thiab kuj yog siv los ua epoxy curing agents. Lub thermal deformation kub ntawm cov khoom epoxy resin kho los ntawm cov khoom yog hais txog 180 degree, thiab cov kuj yog zoo, thiab chloropontic acid kuj yog siv los ua ib tug dye intermediate thiab tshuaj tua kab. Nws kuj yog siv los ua cov nplaim hluav taws xob rau cov ntaub. Siv los ua cov nplaim hluav taws retardant curing tus neeg saib xyuas rau epoxy resins. Cov resin yog kho thaum ua kom nws refractory. Refractory epoxy resin yog siv los ua ib lub sealant rau semiconductors. Siv los ua tus neeg sawv cev kho ntawm epoxy resin, siv ntau npaum li 100 ~ 110 qhov loj. Kev kho mob 2 h + 100 degree / 160 degree lossis 120 degree / 4 h / 2 h + 180 degree lossis 100 degree / 1/4 hhh + 200 degree rau + 160 degree / 4/1 h. Cov khoom siv kho mob muaj cov nplaim hluav taws zoo heev, hluav taws xob thiab khoom siv hluav taws xob, thiab cov tshuaj tiv thaiv zoo heev. Thermal deformation kub 181 degree. Chloropneumatic anhydride thiab chloropneumatic acid kuj tseem siv tau los ua cov nplaim hluav taws kub nyhiab, haum rau polyester, polyurethane thiab unsaturated polyester. Chloroponic acid yog ib qho dyestuff nruab nrab thiab nplaim taws retardant rau tshuaj tua kab thiab ntaub.

Txoj kev tsim khoom yog cov tshuaj tiv thaiv ntawm hexachlorocyclopentadiene nrog maleic anhydride. Xovxwm hexachlorocyclopentadiene thiab maleic anhydride rau 1: Cov molar ratio ntawm 1.1 yog tov nyob rau hauv cov kuab tshuaj chlorobenzene, thiab tom qab cov tshuaj tiv thaiv ntawm 140-145 degree rau 7-8h, ​​cov tshuaj tiv thaiv cov khoom yog ntxiv rau dej rau hydrolysis, thiab cov hydrolyzed chloropontic acid tau ntawm 70 degree dhau los ua cov roj zoo li cov kua dej, uas yog rhuab mus rau 96-97 degree thiab miscible nrog dej, thiab ua Het acid[115-28-6] uas muaj cov dej siv lead ua tom qab txias. Yog tias cov khoom siv tshuaj tiv thaiv yog crystallized nrog dej kub thiab dilute acetic acid, thiab cov monohydrate qhuav ntawm 100-105 degree, chloropontic anhydride tau txais.
