I-1,4 i-butynediol eyomeleleyo imveliso ephezulu
CAS:110-65-6
Iimpawu zeMichiza ye-butynediol: ikristale emhlophe ye-orthorhombic.Indawo yokunyibilika 58 ℃, iqondo lokubila 238 ℃, 145 ℃ (2KPa), i-flash point 152 ℃, i-refractive index 1.450.Inyibilika emanzini, isisombululo se-asidi, i-ethanol kunye ne-acetone, i-soluble kancinane kwi-chloroform, ayinyibiliki kwi-benzene kunye ne-ether.
Ukusetyenziswa: i-butynediol ingasetyenziselwa ukuvelisa i-butene glycol, i-butynediol, i-n-butanol, i-dihydrofuran, i-tetrahydrofuran γ- Uluhlu lweemveliso ezibalulekileyo ze-organic ezifana ne-butyrolactone kunye ne-pyrrolidone zingasetyenziselwa ukuvelisa iiplastiki zokwenziwa, ii-synthetic fibers (nylon-4), yesikhumba eyenziweyo, iyeza, i-pesticides, i-solvents (i-N-methyl pyrrolidone) kunye ne-preservatives.I-Butynediol ngokwayo sisinyibilikisi esilungileyo kwaye sisetyenziswa njengento ekhanyayo kwishishini le-electroplating.

Ulwelo olumthubi olumthubi oluyityhefu kakhulu 1,4-butynediol
I-1,4-butynediol eqinileyo, i-chemical formula C4H6O2, i-crystal orthorhombic emhlophe.Inyibilika emanzini, iasidi, i-ethanol kunye ne-acetone, ayinyibiliki kwi-benzene kunye ne-ether.Inokucaphukisa i-mucous membrane, ulusu kunye nomphezulu wokuphefumla wamehlo.Kumashishini, i-1,4-butynediol eqinile ilungiselelwe ngokukodwa yindlela ye-Reppe, i-catalyzed yi-butynediol copper okanye i-copper bismuth catalyst, kwaye ilungiswe ngokusabela kwe-acetylene kunye ne-formaldehyde phantsi koxinzelelo (i-1 ~ 20 bar) kunye nokufudumeza (110 ~ 112 ° C) .I-butynediol ekrwada ifumaneka ngokusabela, kwaye imveliso egqityiweyo ifunyenwe ngokugxininiswa kunye nokucocwa.

Ulwelo olunetyhefu ephezulu lugqwesileyo kwimveliso yotywala bepropargyl
Ulwelo olungenambala, oluguquguqukayo olunevumba elinukayo.Kulula ukujika tyheli xa ibekwe ixesha elide, ngakumbi xa ibekwe ekukhanyeni.Ixubene namanzi, benzene, chloroform, 1,2-dichloroethane, ether, ethanol, acetone, dioxane, tetrahydrofuran kunye nepyridine, i-soluble kancinane kwi-carbon tetrachloride, kodwa ayinyibiliki kwi-aliphatic hydrocarbons.
Zonke iimveliso
Ubungcali kwimveliso yotywala bepropargyl, 1,4 butynediol kunye ne-3-chloropropyne
