1,4 butynediol ibicuruzwa bisumba byose
CAS: 110-65-6
Imiterere yimiti ya butynediol: kirisiti yera ya orthorhombic.Gushonga ingingo 58 ℃, ingingo itetse 238 ℃, 145 ℃ (2KPa), flash point 152 ℃, indangagaciro yo kwanga 1.450.Gushonga mumazi, umuti wa aside, Ethanol na acetone, gushonga gake muri chloroform, kudashonga muri benzene na ether.
Imikoreshereze: butynediol irashobora gukoreshwa mugukora butene glycol, butynediol, n-butanol, dihydrofuran, tetrahydrofuran γ- Urukurikirane rwibicuruzwa byingenzi kama nka butyrolactone na pyrrolidone birashobora gukoreshwa mugukora plastike yubukorikori, fibre synthique (nylon-4), uruhu rwubukorikori, ubuvuzi, imiti yica udukoko, imiti (N-methyl pyrrolidone) hamwe nuburinda.Butynediol ubwayo nigisubizo cyiza kandi ikoreshwa nkurumuri mumashanyarazi.

Umuhondo wijimye wijimye cyane 1,4-butynediol
1,4-butynediol ikomeye, imiti ya C4H6O2, kirisiti yera ya orthorhombic.Gushonga mumazi, aside, Ethanol na acetone, kudashonga muri benzene na ether.Irashobora kurakaza ururenda, uruhu hamwe nubuhumekero bwo hejuru bwamaso.Mu nganda, 1,4-butynediol ikomeye itegurwa cyane cyane nuburyo bwa Reppe, igatangizwa na butynediol y'umuringa cyangwa umuringa wa bismuth, kandi igategurwa na reaction ya acetylene na formaldehyde munsi yigitutu (1 ~ 20 bar) no gushyushya (110 ~ 112 ° C) .Butynediol itaboneka iboneka binyuze mubitekerezo, kandi ibicuruzwa byarangiye biboneka binyuze mubitekerezo no gutunganya.

Uburozi bukabije bwamazi arenze ibicuruzwa propargyl alcoho
Ibara ritagira ibara, rihindagurika rifite impumuro mbi.Biroroshye guhinduka umuhondo iyo ushyizwe umwanya muremure, cyane cyane iyo uhuye numucyo.Ntibishobora gukoreshwa namazi, benzene, chloroform, 1,2-dichloroethane, ether, Ethanol, acetone, dioxane, tetrahydrofuran na pyridine, bigashonga igice muri tetrachloride ya karubone, ariko ntibishobora gushonga muri hydrocarbone ya alifatique.
Ibicuruzwa byose
Inzobere mu gukora inzoga za propargyl, 1,4 butynediol na 3-chloropropyne
