Uketshezi oluphuzi oluphaphathekile olunobuthi obuphezulu 1,4-butynediol

Incazelo emfushane:

I-1,4-butynediol eqinile, ifomula yamakhemikhali engu-C4H6O2, ikristalu emhlophe ye-orthorhombic.Incibilika emanzini, i-asidi, i-ethanol ne-acetone, ayincibiliki ku-benzene ne-ether.Ingacasula ulwelwesi lwamafinyila, isikhumba kanye nomgudu wokuphefumula ongaphezulu wamehlo.Embonini, okuqinile kwe-1,4-butynediol kulungiselelwe ngokuyinhloko indlela ye-Reppe, eyenziwe nge-butynediol yethusi noma i-copper bismuth catalyst, futhi ilungiswa ngokusabela kwe-acetylene ne-formaldehyde ngaphansi kwengcindezi (1 ~ 20 bar) kanye nokufudumeza (110 ~ 112 ° C) .I-butynediol engahluziwe itholakala ngokusabela, futhi umkhiqizo oqediwe utholakala ngokugxila nokucwengisiswa.

Incazelo Yomkhiqizo

1, 4 ukusetshenziswa okuyinhloko kwe-butynediol:ye-organic synthesis, esetshenziswa njenge-electroplating brightener.

I-1,4-butynediol ingasetshenziselwa ukukhiqiza i-butene glycol, i-butanediol, i-n-butanol, i-dihydrofuran, i-tetrahydrofuran γ- Uchungechunge lwemikhiqizo ebalulekile ye-organic efana ne-butyrolactone ne-pyrrolidone ingasetshenziswa futhi ukukhiqiza amapulasitiki okwenziwa, imicu yokwenziwa (inayiloni-4 ), isikhumba sokwenziwa, imithi, izibulala-zinambuzane, ama-solvents (N-methyl pyrrolidone) kanye nezivimbelakuvunda.

Ukubukeka:i-rhombic crystal emhlophe noma ephuzi ephuzi emhlophe (ophuzi okhanyayo ngemva kokumuncwa komswakama)_ iphuzu:58℃Boiling_ point 238℃，145℃(2kPa）flash_ Point 152 ℃ refractive index 1.450 solubility encibilika emanzini, isixazululo se-asidi, ethanol kancane, ethanol I-chloroform, engancibiliki ku-benzene nakwezinye izakhiwo i-ether eqinile i-butynediol kulula ukuyidla emoyeni eku-25 ° C, inezici zamakhemikhali zotshwala obuyisisekelo obunambambili, futhi ingakwazi ukwenza ukusabela okwengeza.

Izingozi ezingokomzimba namakhemikhali:uma kuba nokushisa okuphezulu, umlilo ovulekile noma kuxutshwe ne-oxidant, kunengozi yokusha nokuqhuma ngenxa yokungqubuzana nomthelela.Emazingeni okushisa aphezulu, uma kungcoliswe usawoti we-mercury, i-asidi eqinile, i-alkaline earth metal, i-hydroxide ne-halide, ukuqhuma kungase kwenzeke.

Imithetho yesitoreji:gcina endaweni epholile nengena umoya.Gcina kude nomlilo nomthombo wokushisa.Ukuvalwa kwephakheji.Izogcinwa ngokuhlukana nama-oxidants, ama-alkali namakhemikhali adliwayo, futhi isitoreji esixutshiwe ngeke sivunyelwe.Kuzokwamukelwa izibani ezivikela ukuqhuma kanye nezindawo zokungenisa umoya.Akuvunyelwe ukusebenzisa imishini namathuluzi alula ukukhiqiza izinhlansi.Indawo yokugcina kufanele ifakwe izinto ezifanele ukuqukatha ukuvuza.

Izindawo zokuhlala ezengeziwe e-Henan Haiyuan Fine Chemical Co., Ltd.:I-1,4-butynediol eqinile, entsha ngaphandle kobuthi, ikhwalithi enhle kakhulu.

Okwedlule: 1,4 butynediol umkhiqizo oqinile ophakeme

Olandelayo: 3-chloropropyne uketshezi oluvuthayo olungenambala olunobuthi obuphezulu
