Ụfọdụ ihe ọmụma gbasara AIBN (CAS:78-67-1)

1.Aha Bekee:2,2′-Azobis(2-methylpropionitrile)

2.Njirimara kemịkalụ:

Kristal ọcha ma ọ bụ kristal ntụ ntụ ọcha. A naghị agbaze na mmiri, a naghị agbaze na ihe mgbaze organic dịka methanol, ethanol, acetone, ether, petroleum ether na aniline.

3. Ebumnuche:

Dịka ihe mmalite maka imepụta polymerization nke vinyl chloride, vinyl acetate, acrylonitrile na monomers ndị ọzọ, yana ihe na-eme ka roba na plastik jupụta, usoro ọgwụgwọ ahụ bụ 10% ~ 20%. Enwere ike iji ngwaahịa a mee ihe dị ka ihe na-eme ka ihe dị nro, ọgwụ kemịkalụ ọrụ ugbo, na ihe dị n'etiti na mmepụta organic. Ngwaahịa a bụ ihe na-egbu egbu nke ukwuu. LD5017.2-25mg/kg nke ọnụ na òké nwere ike ibute nnukwu nsí nye ụmụ mmadụ n'ihi ntọhapụ nke cyanide organic n'oge okpomọkụ na-ere ọkụ.

4. Usoro mmepụta:

A na-eji Acetone, hydrazine hydrate na Sodium cyanide eme ihe dị ka ihe eji emepụta ihe: okpomọkụ mmeghachi omume Condensation dị n'elu bụ 55 ~ 60 ℃, oge mmeghachi omume bụ awa 5, wee jụọ oyi ruo 25 ~ 30 ℃ maka awa 2. Mgbe okpomọkụ dara n'okpuru 10 ℃, a na-ewebata chlorine ma mmeghachi omume ahụ na-eme n'okpuru 20 ℃ na Chemicalbook. Oke ihe onwunwe bụ: HCN: acetone: hydrazine=1L: 1.5036kg: 0.415kg. Acetone cyanohydrin na-emeghachi omume na hydrazine hydrate, wee oxidizes na mmiri mmiri chlorine ma ọ bụ aminobutyronitrile na Sodium hypochlorite.

5. Okpomọkụ mmalite nke onye na-ebido

AIBN bụ ihe na-akpali Radical nke ọma. Mgbe a na-ekpo ọkụ ya ruo ihe dị ka 70 Celsius, ọ ga-agbaze ma wepụta nitrogen ma mepụta free radical (CH3) 2CCN. Free radical ahụ kwụsiri ike n'ihi mmetụta nke otu cyano. Ọ nwere ike imeghachi omume na ihe ndị ọzọ dị ndụ ma gbanwee ghọọ free radical ọhụrụ ebe ọ na-ebibi onwe ya, si otú a na-akpali mmeghachi omume Chain nke free radicals (lee Free Radical Reaction). N'otu oge ahụ, enwere ike ijikọ ya na molekul abụọ site na Chemicalbook iji mepụta tetramethyl Succinonitrile (TMSN) nwere nsí siri ike. Mgbe ọ na-ekpo ọkụ AIBN ruo 100-107 ° C, ọ na-agbaze ma na-agbaze ngwa ngwa, na-ewepụta nitrogen gas na ọtụtụ ihe ndị na-egbu egbu organic nitrile, nke nwekwara ike ibute mgbawa na ọkụ. Jiri nwayọ gbazee na okpomọkụ ụlọ ma chekwaa ya n'okpuru 10 ° C. Debe ya na ọkụ na isi iyi okpomọkụ. Nsí. A na-agbanwe ya ka ọ bụrụ hydrocyanic acid n'ime anụ ahụ anụmanụ dịka ọbara, imeju, na ụbụrụ.

6. Njirimara nchekwa na njem:

① Nkewa nke ihe ndị na-egbu egbu: Nsị

② Àgwà ihe egwu mgbawa: nwere ike ịgbawa mgbe agwakọtara ya na ihe ndị na-eme ka ihe dị n'ime ya dị ọcha; Ọ dị mfe ịgbawa, ọ naghị eguzosi ike, ọ na-agbawa nke ọma n'okpuru okpomọkụ, ma na-agbawa mgbe ejiri heptane na acetone kpoo ya ọkụ.

③ Àgwà ihe ize ndụ nke ire ọkụ: Ọ na-ere ọkụ n'ihu ọkụ mepere emepe, okpomọkụ dị elu, na ihe ndị na-eme ka oxidation dị; Ọ na-agbaze gas ndị na-ere ọkụ mgbe a na-ekpughere ha na okpomọkụ; Ọkụ na-emepụta anwụrụ ọkụ nitrogen oxide na-egbu egbu

④ Njirimara nchekwa na njem: ikuku ikuku n'ụlọ nkwakọba ihe, ihicha obere okpomọkụ; Debe iche na ihe ndị na-eme ka ihe dị n'ime ya ghara ịdị

⑤ Ihe na-eme ka ihe gbanyụọ: mmiri, ájá akọrọ, carbon dioxide, ụfụfụ, ihe na-eme ka ihe gbanyụọ 1211
