4,4′-Oxybis(benzoyl Chloride)/DEDC cas:7158-32-9

Inkcazelo emfutshane:

I-4,4-chloroformylphenylene etha, ekwabizwa ngokuba yi-CFPE, yikhompawundi yemichiza efumana usetyenziso olumandla kuluhlu olubanzi lwezicelo zoshishino.Ingumgubo ophuzi kunye ne-molecular formula ye-C8H4Cl2O kunye ne-molecular weight of 191.03 g / mol.CFPE ikakhulu isetyenziswa njenge intermediate reactive in ezahlukeneyo syntheses, eyenza ukuveliswa iipholima eliphezulu-ukusebenza kunye copolymers.

Iinkcukacha zeMveliso

Iithegi zeMveliso

1. Imbonakalo kunye neePropati:

I-ether yethu ye-4,4-chloroformylphenylene ibonisa iimpawu ezibonakalayo ezibonakalayo.Kubonakala ngathi ngumgubo omthubi, unozinzo olubalaseleyo lwe-thermal kunye nokumelana nokuthotywa kweekhemikhali.I-CFPE inendawo yokunyibilika emalunga ne-180°C kunye nendawo yokubilisa malunga ne-362°C. Iyanyibilika kwizinyibilikisi ezifana neehydrocarbon ezikloriniwe, iialkoholi, kunye ne-ethers.

2. Usetyenziso:

I-4,4-chloroformylphenylene ether isetyenziswa ngokubanzi njengebhloko yokwakha engundoqo ekuhlanganiseni kweepolymers ezahlukeneyo eziphezulu zokusebenza, ezifana ne-polyphenylene sulfide (PPS) kunye ne-polyether ether ketone (PEEK).Ezi polymers zifunwa ngenxa yozinzo lwazo olukhethekileyo lwe-thermal, amandla omatshini, kunye nokumelana neekhemikhali, zizenza zilungele usetyenziso lwemizi-mveliso.

3. Iimpawu ezongezelelweyo kunye neeNzuzo:

- High reaction ukusebenza kakuhle: Ulwakhiwo imichiza CFPE kaThixo ivumela ukufakwa esebenzayo kumatyathanga polymer, kubangele ukusebenza imveliso eyandisiweyo.

- Ukomelezwa idangatye-retardancy: CFPE-eziqulathe iipholima umboniso egqwesileyo ukumelana idangatye, ibenza ilungele izicelo ezifuna imithetho yokhuseleko umlilo.

- Inertness Chemical: Iipropati ezizodwa CFPE yenza ukuba ukumelana imichiza ezininzi ezonakalisayo, ukwandisa ubomi imveliso ekupheleni.

4. Ukupakishwa kunye nokuphatha:

I-ether yethu ye-4,4-chloroformylphenylene ifakwe kwiibhotile ezingenawo umoya ukuze kuqinisekiswe ukuzinza kwayo ngexesha lokuthutha kunye nokugcinwa.Kunconywa ukugcina imveliso kwindawo epholileyo, eyomileyo kude nelanga elithe ngqo kunye nezinto ezingahambelaniyo.Iinkqubo zokuphatha ezifanelekileyo kufuneka zilandelwe ngexesha lokuthutha kunye nokusetyenziswa ukuqinisekisa ukhuseleko oluphezulu kunye nokuthintela umngcipheko wosulelo.
