1,3 Butadiene (C4H6)

Imingcele yezobuchwepheshe

I-1,3-Butadiene iyinhlanganisela ephilayo enefomula yamakhemikhali ye-C4H6. Kuyigesi engenambala enephunga elincane elimnandi futhi kulula ukuyincibilika. Ayinabuthi obuncane futhi ubuthi bayo bufana ne-ethylene, kodwa inokucasuka okunamandla esikhumbeni kanye nolwelwesi lwamafinyila, futhi inomphumela wokubulala izinzwa ekugxilweni okuphezulu. 1,3 I-Butadiene iyavutha futhi ingakha ingxube eqhumayo lapho ixutshwe nomoya; kulula ukuyishisa futhi iqhume lapho ibhekene nokushisa, izinhlansi, amalangabi noma ama-oxidants; uma ihlangabezana nokushisa okuphezulu, ukusabela kwe-polymerization kungase kwenzeke, ukukhulula ukushisa okuningi futhi kubangele ukuphuka kweziqukathi kanye nezingozi zokuqhuma; Isinda kunomoya, ingasakazekela ebangeni elikhulu endaweni ephansi, futhi izobangela ukuqubuka komlilo lapho ihlangana nelangabi elivulekile. I-1,3 butadiene iyashiswa futhi iboliswe ibe yi-carbon monoxide ne-carbon dioxide. Ayincibiliki emanzini, iyancibilika ku-ethanol ne-methanol, futhi incibilika kalula kuzincibilikisi eziningi eziphilayo njenge-acetone, i-ether ne-chloroform. I-1,3 i-Butadiene iyingozi emvelweni futhi ingabangela ukungcola emanzini, inhlabathi kanye nomkhathi. I-1,3 i-Butadiene ingumkhiqizi oyinhloko werabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, i-neoprene) nama-resin ahlukahlukene anezinhlobonhlobo zokusetshenziswa (njenge-ABS resin, i-SBS resin, i-BS resin, i-MBS resin) impahla, i-butadiene nayo inokusetshenziswa okuningi ekukhiqizeni amakhemikhali amahle. I-1,3 butadiene kufanele igcinwe endaweni epholile, nengena umoya ukuze kutholakale amagesi avuthayo. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-halogen, njll., futhi igweme isitoreji esixubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

①Ukukhiqizwa kwerabha yokwenziwa:

I-1,3 i-Butadiene iwumthombo oyinhloko wokukhiqizwa kwerabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, ne-neoprene)

②Izinto zokusetshenziswa zamakhemikhali eziyisisekelo:

I-Butadiene ingaphinde icutshungulwe ukuze ikhiqize i-hexamethylene diamine ne-caprolactam, ibe enye yezinto zokusetshenziswa ezibalulekile zokulungiswa kwenayiloni.

③Ikhemikhali enhle:

Amakhemikhali amahle enziwe nge-butadiene njengezinto zokusetshenziswa.
