Tert-butyl peroxybenzoate yog feem ntau siv cov organic peroxide thiab dav siv los ua tus thawj coj hauv cov txheej txheem polymerization xws li ethylene, styrene, propylene, vinyl acetate, diallyl phthalate, thiab isobutylene. Nyob rau hauv cov txheej txheem curing ntawm unsaturated polyester, nws yog dav siv nyob rau hauv molding txheej txheem xws li SMC, BMC, DMC rub cov neeg ua hauj lwm, thiab kuj yuav siv tau nyob rau hauv ob lub ntsiab curing systems nrog ntau dua kev ua si xws li MEPK, BPO, los yog TBPO. Hauv qab no yog cov lus qhia luv luv rau cov txheej txheem tsim khoom ntawm Tert-butyl peroxybenzoate.
Kauj Ruam 1: Sodium ntsev synthesis
1) Npaj 10% diluted alkali nrog ionic membrane alkali thiab dej huv;
2) Nyob rau hauv nplawm thiab khov, ntxiv crude tert butyl hydrogen peroxide (feem ntau hu ua tert lossis crude tert) dropwise, tswj qhov kub hauv lub hwj kom tsawg dua 30 degree, txuas ntxiv stirring rau ib nrab ib teev, nres stirring, thiab cia. nws sawv ntsug li 1 teev ua ntej cais tawm sodium ntsev rau thaub qab; Cov txheej sab saud ntawm sodium tert tuaj yeem raug muag raws li cov khoom tiav tom qab ntxuav alkaline.
Kauj ruam 2: Synthesis ntawm crude Tert-butyl peroxybenzoate
1) Ntxiv sodium ntsev ncaj qha mus rau lub reactor, do thiab khov;
2) Pib ntxiv benzoyl chloride dropwise thaum qhov kub ntawm cov tshuaj tiv thaiv hluav taws xob tsawg dua lossis sib npaug li 20 degree;
3) Tswj lub tee dej acceleration raws li qhov kub thiab txias ntawm cov tshuaj tiv thaiv kettle, thiab tswj qhov kub hauv lub hwj kom tsawg dua los yog sib npaug li 30 degree;
4) Tom qab dripping benzoyl chloride, txuas ntxiv stirring rau 2 teev, nres stirring, cia sawv ntsug rau 1 teev, thiab ces cais lub qis niam cawv rau kev kho dej khib nyiab; Cov txheej sab saud yog cov khoom nyoos ntawm Tert-butyl peroxybenzoate.
Kauj Ruam 3: Ntxuav thiab ziab
1) Pib nplawm thiab khov, tswj qhov kub ntawm tag nrho cov txheej txheem ntxuav thiab ziab kom tsawg dua lossis sib npaug li 30 degree thoob plaws tag nrho cov txheej txheem;
2) Npaj 10% dilute alkali tov thiab ntxuav nws hauv 1: 1 piv rau cov khoom nyoos ntawm tTert-butyl peroxybenzoate rau 1 teev. Cia nws sawv ntsug rau 30 feeb thiab txheej los ntawm txheej. Cais cov txheej hauv qab ntawm kev ntxuav alkali thiab pov tseg ntawm peb qhov pov tseg;
3) Txuas ntxiv tawm cov crude Tert-butyl peroxybenzoate nyob rau hauv lub reactor, ntxuav nws nrog ib tug 5% baking soda tov ntawm li 1/2 ratio rau 1 teev, cia nws sawv ntsug rau 30 feeb, thiab txheej los ntawm txheej. Cais cov txheej txheej sab saud ntawm cov tshuaj ntxuav tes rau kev kho peb cov khib nyiab;
4) Cov khoom nyoos ntawm Tert-butyl peroxybenzoate yog qhuav nrog txog 20 kilograms ntawm anhydrous magnesium sulfate, thiab tom qab ntawd lim kom tau cov khoom tiav ntawm Tert-butyl peroxybenzoate.
