Nws kuj tseem siv tau los tsim cov tshuaj tua kab ua liaj ua teb uas muaj cov qauv chlortetracyclic acid.Raws li cov ntsiab lus chlorine hauv HET acid yog li 54.4%, nws ruaj khov heev rau dej, cawv, alkali, thiab lwm yam, yog li cov khoom siv hluavtaws muaj qhov zoo tiv thaiv corrosion thiab nplaim retardancy.Nws tau dav siv nyob rau txawv teb chaws nyob rau hauv chlor alkali los yog kub ntub dej chlorine, hydrochloric acid, ntsev dej thiab lwm yam sij hawm nyob rau hauv lub pulp kev lag luam, raws li zoo raws li cov dej phwj tuaj, khib nyiab roj, pov tseg residue, isopropanol, sulfur dioxide thiab lwm yam teb.Appearance: dawb , tsis muaj plua plav me me Crystal Purity: siab dua 99.0% Cov ntsiab lus chlorine: 54.4% ± 0.2% Xim: qis dua 50 (Heinstein xim tus nqi) Cov teeb meem tsis zoo: qis dua 1.0% |
| Chlorendic anhydride | 115-27-5 ib | Chlorine bridged anhydride yog cov organic compound nrog cov tshuaj formula C9H2Cl6O3.CAS tus lej sau npe: 115-27-5 Suav lub npe: chlorobridged anhydride;1,4,5,6,7,7-Hexachloro-5-norbornene-2,3-dicarboxylic anhydridePhysicochemical khoom kho cov tshaj tawm cov ntsiab lus melting: 235-240º C Dej solubility: insoluble khoom piav qhia dawb siv lead ua.Melting point 231-235 ℃.Solubility (g / 100g): benzene yog 40.4, hexane yog 4.5, acetone yog 127.0, carbon tetrachloride yog 6.7, me ntsis soluble hauv dej thiab hydrolyzed rau chlorobridge acid.Ob qho tib si chlorobridged anhydride thiab chlorobridged acid yog cov nplaim hluav taws kub nyhiab, haum rau cov tsis muaj polyester, polyurethane thiab epoxy resin, nrog rau kev kho tus neeg sawv cev rau epoxy resin.Lub thermal deformation kub ntawm epoxy resin kho los ntawm cov khoom yog hais txog 180 ℃, thiab cov tshuaj tiv thaiv yog zoo.Chlorobridge acid kuj tseem siv los ua cov xim nruab nrab thiab tshuaj tua kab.Nws kuj yog siv los ua cov nplaim hluav taws kub nyhiab rau cov ntaub.Lwm cov ntaub ntawv yog muab tso ua ke los ntawm cov tshuaj tiv thaiv ntawm hexachlorocyclopentadiene thiab maleic anhydride.Sib tov hexachlorocyclopentadiene thiab maleic anhydride hauv cov kuab tshuaj chlorobenzene ntawm molar piv ntawm 1: 1.1.Tom qab 7-8h cov tshuaj tiv thaiv ntawm 140-145 ℃, ntxiv cov tshuaj tiv thaiv rau dej rau hydrolysis.Cov chlorobridge acid tau los ntawm hydrolysis ntawm 70 ℃ dhau los ua kua roj.Thaum rhuab mus rau 96-97 ℃, nws yog miscible nrog dej.Tom qab txias, nws dhau los ua chlorobridge acid uas muaj ib qho dej siv lead ua (Hetacid [115-28-6]).Yog tias cov khoom siv tshuaj tiv thaiv yog crystallized nrog dej kub thiab dilute acetic acid, cov monohydrate qhuav ntawm 100-105 ℃ kom tau chlorobridged anhydride. |
